Chronic Kidney Disease: Definition with Case – Nephrology - Lecturio

The biochemical mechanisms of action of these substances have not yet been thoroughly elucidated. However, when these substances fall below their normal proportions, stones can form from an aggregation of crystals. Sufficient dietary intake of magnesium and citrate inhibits the formation of calcium oxalate and calcium phosphate stones; in addition, magnesium and citrate operate synergistically to inhibit kidney stones. Magnesium's efficacy in subduing stone formation and growth is dose-dependent.

The protective role of citrate is linked to several mechanisms; citrate reduces urinary supersaturation of calcium salts by forming soluble complexes with calcium ions and by inhibiting crystal growth and aggregation. Therapy with potassium citrate or magnesium potassium citrate is commonly prescribed in clinical practice to increase urinary citrate and to reduce stone formation rates. Diagnosis of kidney stones is made on the basis of information obtained from the history, physical examination, urinalysis, and radiographic studies. Pain in the back occurs when calculi produce an obstruction in the kidney. Calcium-containing stones are relatively radiodense , and they can often be detected by a traditional radiograph of the abdomen that includes the kidneys, ureters, and bladder KUB film.

Cystine calculi are only faintly radiodense , while uric acid stones are usually entirely radiolucent. In people with a history of stones, those who are less than 50 years of age and are presenting with the symptoms of stones without any concerning signs do not require helical CT scan imaging. Otherwise a noncontrast helical CT scan with 5 millimeters 0. Where a CT scan is unavailable, an intravenous pyelogram may be performed to help confirm the diagnosis of urolithiasis. This involves intravenous injection of a contrast agent followed by a KUB film. Uroliths present in the kidneys, ureters, or bladder may be better defined by the use of this contrast agent.

Stones can also be detected by a retrograde pyelogram , where a similar contrast agent is injected directly into the distal ostium of the ureter where the ureter terminates as it enters the bladder. Renal ultrasonography can sometimes be useful, because it gives details about the presence of hydronephrosis , suggesting that the stone is blocking the outflow of urine.

Other advantages of renal ultrasonography include its low cost and absence of radiation exposure. Ultrasound imaging is useful for detecting stones in situations where X-rays or CT scans are discouraged, such as in children or pregnant women. On the contrary, a study suggested that ultrasonography should be used as the initial diagnostic imaging test, with further imaging studies be performed at the discretion of the physician on the basis of clinical judgment, and using ultrasonography rather than CT as an initial diagnostic test results in less radiation exposure and equally good outcome. Bilateral kidney stones can be seen on this KUB radiograph. There are phleboliths in the pelvis, which can be misinterpreted as bladder stones.

Axial CT scan of abdomen without contrast, showing a 3-mm stone marked by an arrow in the left proximal ureter. Renal ultrasonograph of a stone located at the pyeloureteric junction with accompanying hydronephrosis. Measurement of a 5. Laboratory investigations typically carried out include [45] [53] [47] [56]. By far, the most common type of kidney stones worldwide contains calcium.

Oxaluria is increased in patients with certain gastrointestinal disorders including inflammatory bowel disease such as Crohn's disease or in patients who have undergone resection of the small bowel or small-bowel bypass procedures. Oxaluria is also increased in patients who consume increased amounts of oxalate found in vegetables and nuts. Primary hyperoxaluria is a rare autosomal recessive condition that usually presents in childhood. Calcium oxalate crystals in urine appear as 'envelopes' microscopically. They may also form 'dumbbells. Using the enzyme urease, these organisms metabolize urea into ammonia and carbon dioxide.

This alkalinizes the urine, resulting in favorable conditions for the formation of struvite stones. Proteus mirabilis , Proteus vulgaris , and Morganella morganii are the most common organisms isolated; less common organisms include Ureaplasma urealyticum and some species of Providencia , Klebsiella , Serratia , and Enterobacter. These infection stones are commonly observed in people who have factors that predispose them to urinary tract infections , such as those with spinal cord injury and other forms of neurogenic bladder , ileal conduit urinary diversion , vesicoureteral reflux , and obstructive uropathies.

They are also commonly seen in people with underlying metabolic disorders, such as idiopathic hypercalciuria , hyperparathyroidism , and gout. Infection stones can grow rapidly, forming large calyceal staghorn antler -shaped calculi requiring invasive surgery such as percutaneous nephrolithotomy for definitive treatment. They also may form in association with conditions that cause hyperuricosuria an excessive amount of uric acid in the urine with or without hyperuricemia an excessive amount of uric acid in the serum. A diagnosis of uric acid urolithiasis is supported by the presence of a radiolucent stone in the face of persistent urine acidity, in conjunction with the finding of uric acid crystals in fresh urine samples.

As noted above section on calcium oxalate stones , people with inflammatory bowel disease Crohn's disease , ulcerative colitis tend to have hyperoxaluria and form oxalate stones. They also have a tendency to form urate stones. Urate stones are especially common after colon resection. Uric acid stones appear as pleomorphic crystals, usually diamond-shaped. They may also look like squares or rods which are polarizable. People with certain rare inborn errors of metabolism have a propensity to accumulate crystal-forming substances in their urine.

For example, those with cystinuria , cystinosis , and Fanconi syndrome may form stones composed of cystine. Cystine stone formation can be treated with urine alkalinization and dietary protein restriction. People afflicted with xanthinuria often produce stones composed of xanthine. People afflicted with adenine phosphoribosyltransferase deficiency may produce 2,8-dihydroxyadenine stones, [64] alkaptonurics produce homogentisic acid stones, and iminoglycinurics produce stones of glycine , proline , and hydroxyproline.

Urolithiasis refers to stones originating anywhere in the urinary system, including the kidneys and bladder. Calyceal calculi are aggregations in either the minor or major calyx , parts of the kidney that pass urine into the ureter the tube connecting the kidneys to the urinary bladder. The condition is called ureterolithiasis when a calculus is located in the ureter. Stones may also form or pass into the bladder, a condition referred to as bladder stones. Stones less than 5 mm 0. Stones that are large enough to fill out the renal calyces are called staghorn stones and are composed of struvite in a vast majority of cases, which forms only in the presence of urease-forming bacteria. Other forms that can possibly grow to become staghorn stones are those composed of cystine, calcium oxalate monohydrate, and uric acid.

Preventative measures depend on the type of stones. In those with calcium stones, drinking plenty of fluids, thiazide diuretics and citrate are effective as is allopurinol in those with high uric acid levels in the blood or urine. Specific therapy should be tailored to the type of stones involved. Diet can have an effect on the development of kidney stones. Preventive strategies include some combination of dietary modifications and medications with the goal of reducing the excretory load of calculogenic compounds on the kidneys. Maintenance of dilute urine by means of vigorous fluid therapy is beneficial in all forms of kidney stones, so increasing urine volume is a key principle for the prevention of kidney stones. Fluid intake should be sufficient to maintain a urine output of at least 2 litres 68 US fl oz per day.

However, the evidence supporting these findings is uncertain. Calcium binds with available oxalate in the gastrointestinal tract, thereby preventing its absorption into the bloodstream, and reducing oxalate absorption decreases kidney stone risk in susceptible people. The preferred calcium supplement for people at risk of stone formation is calcium citrate because it helps to increase urinary citrate excretion.

Aside from vigorous oral hydration and eating more dietary calcium, other prevention strategies include avoidance of large doses of supplemental vitamin C and restriction of oxalate-rich foods such as leaf vegetables , rhubarb , soy products and chocolate. The mainstay for medical management of uric acid stones is alkalinization increasing the pH of the urine. Uric acid stones are among the few types amenable to dissolution therapy, referred to as chemolysis. Chemolysis is usually achieved through the use of oral medications, although in some cases, intravenous agents or even instillation of certain irrigating agents directly onto the stone can be performed, using antegrade nephrostomy or retrograde ureteral catheters.

In addition to acetazolamide or as an alternative, certain dietary supplements are available that produce a similar alkalinization of the urine. These include sodium bicarbonate , potassium citrate , magnesium citrate , and Bicitra a combination of citric acid monohydrate and sodium citrate dihydrate. Increasing the urine pH to around 6. Increasing the urine pH to a value higher than 7. Testing the urine periodically with nitrazine paper can help to ensure the urine pH remains in this optimal range. Using this approach, stone dissolution rate can be expected to be around 10 mm 0. It decreases urinary calcium when combined with food rich in oxalic acid such as green leafy vegetables.

One of the recognized medical therapies for prevention of stones is the thiazide and thiazide-like diuretics , such as chlorthalidone or indapamide. These drugs inhibit the formation of calcium-containing stones by reducing urinary calcium excretion. Thiazides work best for renal leak hypercalciuria high urine calcium levels , a condition in which high urinary calcium levels are caused by a primary kidney defect. Thiazides are useful for treating absorptive hypercalciuria, a condition in which high urinary calcium is a result of excess absorption from the gastrointestinal tract. For people with hyperuricosuria and calcium stones, allopurinol is one of the few treatments that have been shown to reduce kidney stone recurrences.

Allopurinol interferes with the production of uric acid in the liver. The drug is also used in people with gout or hyperuricemia high serum uric acid levels. Hyperuricemia is not necessary for the formation of uric acid stones; hyperuricosuria can occur in the presence of normal or even low serum uric acid. Some practitioners advocate adding allopurinol only in people in whom hyperuricosuria and hyperuricemia persist, despite the use of a urine- alkalinizing agent such as sodium bicarbonate or potassium citrate. Stone size influences the rate of spontaneous stone passage. The use of medications to speed the spontaneous passage of stones in the ureter is referred to as medical expulsive therapy. Extracorporeal shock wave lithotripsy ESWL is a noninvasive technique for the removal of kidney stones.

Most ESWL is carried out when the stone is present near the renal pelvis. ESWL involves the use of a lithotriptor machine to deliver externally applied, focused, high-intensity pulses of ultrasonic energy to cause fragmentation of a stone over a period of around 30—60 minutes. Following its introduction in the United States in February , ESWL was rapidly and widely accepted as a treatment alternative for renal and ureteral stones.

For a stone greater than 10 millimetres 0. Common adverse effects of ESWL include acute trauma , such as bruising at the site of shock administration, and damage to blood vessels of the kidney. On rare occasions, such cases may require blood transfusion and even lead to acute kidney failure. In addition to the aforementioned potential for acute kidney injury, animal studies suggest these acute injuries may progress to scar formation, resulting in loss of functional renal volume. In addition, a retrospective case-control study published by researchers from the Mayo Clinic in has found an increased risk of developing diabetes mellitus and hypertension in people who had undergone ESWL, compared with age and gender-matched people who had undergone nonsurgical treatment.

Whether or not acute trauma progresses to long-term effects probably depends on multiple factors that include the shock wave dose i. The task force published a white paper outlining their conclusions in They concluded the risk-benefit ratio remains favorable for many people. However, they recommended slowing the shock wave firing rate from pulses per minute to 60 pulses per minute to reduce the risk of renal injury and increase the degree of stone fragmentation. Alpha-blockers are sometimes prescribed after shock wave lithotripsy to help the pieces of the stone leave the person's body.

When compared to usual care or placebo treatment, alpha blockers may lead to faster clearing of stones, a reduced need for extra treatment and fewer unwanted effects. The unwanted effects associated with alpha blockers are hospital emergency visits and return to hospital for stone-related issues, but these effects were more common in adults who did not receive alpha-blockers as a part of their treatment. Most stones under 5 mm 0. This approach is still under investigation, though early results are favorable. Ureteroscopy has become increasingly popular as flexible and rigid fiberoptic ureteroscopes have become smaller. One ureteroscopic technique involves the placement of a ureteral stent a small tube extending from the bladder, up the ureter and into the kidney to provide immediate relief of an obstructed kidney.

Stent placement can be useful for saving a kidney at risk for postrenal acute kidney failure due to the increased hydrostatic pressure, swelling and infection pyelonephritis and pyonephrosis caused by an obstructing stone. Ureteral stents vary in length from 24 to 30 cm 9. They are designed to allow urine to flow past an obstruction in the ureter. They may be retained in the ureter for days to weeks as infections resolve and as stones are dissolved or fragmented by ESWL or by some other treatment. The stents dilate the ureters, which can facilitate instrumentation, and they also provide a clear landmark to aid in the visualization of the ureters and any associated stones on radiographic examinations.

The presence of indwelling ureteral stents may cause minimal to moderate discomfort, frequency or urgency incontinence, and infection, which in general resolves on removal. Most ureteral stents can be removed cystoscopically during an office visit under topical anesthesia after resolution of urolithiasis. More definitive ureteroscopic techniques for stone extraction rather than simply bypassing the obstruction include basket extraction and ultrasound ureterolithotripsy. Laser lithotripsy is another technique, which involves the use of a holmium : yttrium aluminium garnet Ho:YAG laser to fragment stones in the bladder, ureters, and kidneys. Specifically, the overall success rate is higher, fewer repeat interventions and postoperative visits are needed, and treatment costs are lower after ureteroscopic treatment when compared with ESWL.

These advantages are especially apparent with stones greater than 10 mm 0. However, because ureteroscopy of the upper ureter is much more challenging than ESWL, many urologists still prefer to use ESWL as a first-line treatment for stones of less than 10 mm, and ureteroscopy for those greater than 10 mm in diameter. Kidney stones affect all geographical, cultural, and racial groups. In North America and Europe, the annual number of new cases per year of kidney stones is roughly 0. In the United States, the frequency in the population of urolithiasis has increased from 3.

Men most commonly experience their first episode between 30 and 40 years of age, whereas for women, the age at first presentation is somewhat later. Contrast-enhanced computed tomography CT scanning is routinely used to determine the stage of the renal cell carcinoma in the abdominal and pelvic regions. CT scans have the potential to distinguish solid masses from cystic masses and may provide information on the localization, stage or spread of the cancer to other organs of the patient. Key parts of the human body which are examined for metastatic involvement of renal cell carcinoma may include the renal vein , lymph node and the involvement of the inferior vena cava.

Ultrasonographic examination can be useful in evaluating questionable asymptomatic kidney tumours and cystic renal lesions if Computed Tomography imaging is inconclusive. This safe and non-invasive radiologic procedure uses high frequency sound waves to generate an interior image of the body on a computer monitor. The image generated by the ultrasound can help diagnose renal cell carcinoma based on the differences of sound reflections on the surface of organs and the abnormal tissue masses. Essentially, ultrasound tests can determine whether the composition of the kidney mass is mainly solid or filled with fluid. A Percutaneous biopsy can be performed by a radiologist using ultrasound or computed tomography to guide sampling of the tumour for the purpose of diagnosis by pathology.

However this is not routinely performed because when the typical imaging features of renal cell carcinoma are present, the possibility of an incorrectly negative result together with the risk of a medical complication to the patient may make it unfavourable from a risk-benefit perspective. Magnetic Resonance Imaging MRI scans provide an image of the soft tissues in the body using radio waves and strong magnets. MRI can be used instead of CT if the patient exhibits an allergy to the contrast media administered for the test. Patients on dialysis or those who have renal insufficiency should avoid this contrasting material as it may induce a rare, yet severe, side effect known as nephrogenic systemic fibrosis.

MRI scans should also be considered to evaluate tumour extension which has grown in major blood vessels, including the vena cava , in the abdomen. MRI can be used to observe the possible spread of cancer to the brain or spinal cord should the patient present symptoms that suggest this might be the case. Intravenous pyelogram IVP is a useful procedure in detecting the presence of abnormal renal mass in the urinary tract.

This procedure involves the injection of a contrasting dye into the arm of the patient. The dye travels from the blood stream and into the kidneys which in time, passes into the kidneys and bladder. Renal angiography uses the same principle as IVP, as this type of X-ray also uses a contrasting dye. This radiologic test is important in diagnosing renal cell carcinoma as an aid for examining blood vessels in the kidneys. This diagnostic test relies on the contrasting agent which is injected in the renal artery to be absorbed by the cancerous cells.

This is imperative for surgeons as it allows the patient's blood vessels to be mapped prior to operation. The staging of renal cell carcinoma is the most important factor in predicting its prognosis. The gross and microscopic appearance of renal cell carcinomas is highly variable. The renal cell carcinoma may present reddened areas where blood vessels have bled, and cysts containing watery fluids. Gross examination often shows a yellowish, multilobulated tumor in the renal cortex , which frequently contains zones of necrosis , haemorrhage and scarring.

Sarcomatoid changes morphology and patterns of IHC that mimic sarcoma, spindle cells can be observed within any RCC subtype and are associated with more aggressive clinical course and worse prognosis. Under light microscopy, these tumour cells can exhibit papillae , tubules or nests, and are quite large, atypical, and polygonal. Recent studies have brought attention to the close association of the type of cancerous cells to the aggressiveness of the condition. Some studies suggest that these cancerous cells accumulate glycogen and lipids, their cytoplasm appear "clear", the nuclei remain in the middle of the cells, and the cellular membrane is evident.

The stroma is reduced, but well vascularised. The tumour compresses the surrounding parenchyma , producing a pseudocapsule. The most common cell type exhibited by renal cell carcinoma is the clear cell , which is named by the dissolving of the cells' high lipid content in the cytoplasm. The clear cells are thought to be the least likely to spread and usually respond more favourably to treatment. However, most of the tumours contain a mixture of cells. The most aggressive stage of renal cancer is believed to be the one in which the tumour is mixed, containing both clear and granular cells.

This system categorises renal cell carcinoma with grades 1, 2, 3, 4 based on nuclear characteristics. The details of the Fuhrman grading system for RCC are shown below: [62]. Nuclear grade is believed to be one of the most imperative prognostic factors in patients with renal cell carcinoma. The risk of renal cell carcinoma can be reduced by maintaining a normal body weight. If it has spread outside of the kidneys, often into the lymph nodes , the lungs or the main vein of the kidney, then multiple therapies are used including surgery and medications.

RCC is resistant to chemotherapy and radiotherapy in most cases but does respond well to immunotherapy with interleukin-2 or interferon-alpha, biologic, or targeted therapy. In early-stage cases, cryotherapy and surgery are the preferred options. Active surveillance or "watchful waiting" is becoming more common as small renal masses or tumours are being detected and also within the older generation when surgery is not always suitable.

The recommended treatment for renal cell cancer may be nephrectomy or partial nephrectomy , surgical removal of all or part of the kidney. This allows for more renal preservation as compared to the radical nephrectomy, and this can have positive long term health benefits. Surgical nephrectomy may be "radical" if the procedure removes the entire affected kidney including Gerota's fascia , the adrenal gland which is on the same side as the affected kidney, and the regional retroperitoneal lymph nodes, all at the same time. But it is not always appropriate, as it is a major surgery that contains the risk of complication both during and after the surgery and can have a longer recovery time.

In cases where the tumor has spread into the renal vein, inferior vena cava, and possibly the right atrium, this portion of the tumor can be surgically removed, as well. When the tumor involved the inferior vena cava, it is important to classify which parts of the vena cava are involved and to plan accordingly, as sometimes complete resection will involve an incision into the chest with increased morbidity. For this reason, Dr. Gaetano Ciancio , adapted liver mobilization techniques from liver transplant to address retrohepatic or even suprahepatic inferior vena caval thrombus associated with renal tumors. Kidneys are sometimes embolized prior to surgery to minimize blood loss.

Surgery is increasingly performed via laparoscopic techniques. Commonly referred to as key hole surgery, this surgery does not have the large incisions seen in a classically performed radical or partial nephrectomy, but still successfully removes either all or part of the kidney. Laparoscopic surgery is associated with shorter stays in the hospital and quicker recovery time but there are still risks associated with the surgical procedure. These have the advantage of being less of a burden for the patient and the disease-free survival is comparable to that of open surgery.

This may involve temporarily stopping blood flow to the kidney while the mass is removed as well as renal cooling with an ice slush. Mannitol can also be administered to help limit damage to the kidney. This is usually done through an open incision although smaller lesions can be done laparoscopically with or without robotic assistance. Laparoscopic cryotherapy can also be done on smaller lesions.

Typically a biopsy is taken at the time of treatment. Intraoperative ultrasound may be used to help guide placement of the freezing probes. As the tumor is not removed followup is more complicated see below and overall disease-free rates are not as good as those obtained with surgical removal. Surgery for metastatic disease: If metastatic disease is present surgical treatment may still a viable option. Radical and partial nephrectomy can still occur, and in some cases, if the metastasis is small this can also be surgically removed.

Percutaneous ablation therapies use image-guidance by radiologists to treat localized tumors if a surgical procedure is not a good option. Although the use of laparoscopic surgical techniques for complete nephrectomies has reduced some of the risks associated with surgery, [79] surgery of any sort in some cases will still not be feasible. For example, the elderly, people already suffering from severe renal dysfunction, or people who have several comorbidities , surgery of any sort is not warranted. A probe is placed through the skin and into the tumor using real-time imaging of both the probe tip and the tumor by computed tomography , ultrasound , or even magnetic resonance imaging guidance, and then destroying the tumor with heat radiofrequency ablation or cold cryotherapy.

These modalities are at a disadvantage compared to traditional surgery in that pathologic confirmation of complete tumor destruction is not possible. Therefore, long-term follow-up is crucial to assess completeness of tumour ablation. However, there are some cases where ablation can be used on tumors that are larger. The two main types of ablation techniques that are used for renal cell carcinoma are radio frequency ablation and cryoablation. Radio frequency ablation uses an electrode probe which is inserted into the affected tissue, to send radio frequencies to the tissue to generate heat through the friction of water molecules. The heat destroys the tumor tissue. Cryoablation also involves the insertion of a probe into the affected area, [9] however, cold is used to kill the tumor instead of heat.

The probe is cooled with chemical fluids which are very cold. The freezing temperatures cause the tumor cells to die by causing osmotic dehydration , which pulls the water out of the cell destroying the enzyme , organelles , cell membrane and freezing the cytoplasm. Cancers often grow in an unbridled fashion because they are able to evade the immune system. Other targeted therapy medications inhibit growth factors that have been shown to promote the growth and spread of tumours. For patients with metastatic cancer, sunitinib probably results in more progression of the cancer than pembrolizumab, axitinib and avelumab.

Activity has also been reported for ipilimumab [94] but it is not an approved medication for renal cancer. More medications are expected to become available in the near future as several clinical trials are currently being conducted for new targeted treatments, [96] including: atezolizumab , varlilumab , durvalumab , avelumab , LAG , MBG , TRC , and savolitinib. Chemotherapy and radiotherapy are not as successful in the case of RCC. Adjuvant therapy , which refers to therapy given after a primary surgery, has not been found to be beneficial in renal cell cancer. In some cases neoadjuvant therapy has been shown to decrease the size and stage of the RCC to then allow it to be surgically removed.

Metastatic renal cell carcinoma mRCC is the spread of the primary renal cell carcinoma from the kidney to other organs. MRCC has a poor prognosis compared to other cancers although average survival times have increased in the last few years due to treatment advances. Average survival time in for the metastatic form of the disease was under a year [] and by this improved to an average of 22 months. Options include interleukin-2 which is a standard therapy for advanced renal cell carcinoma. The drugs aim to inhibit the growth of new blood vessels in the tumors, hence slowing growth and in some cases reducing the size of the tumors. Radiotherapy and chemotherapy are more commonly used in the metastatic form of RCC to target the secondary tumors in the bones, liver, brain and other organs.

While not curative, these treatments do provide relief for suffers from symptoms associated with the spread of tumors. The prognosis is influenced by several factors, including tumour size, degree of invasion and metastasis, histologic type, and nuclear grade. The following numbers are based on patients first diagnosed in and by the National Cancer Data Base: []. For instance, younger people among 20—40 years old have a better outcome despite having more symptoms at presentation, possibly due to lower rates spread of cancer to the lymph nodes stage III.

Some people have the renal cell cancer detected before they have symptoms incidentally because of the CT scan Computed Tomography Imaging or ultrasound. Incidentally diagnosed renal cell cancer no symptoms differs in outlook from those diagnosed after presenting symptoms of renal cell carcinoma or metastasis. The 5 year survival rate was higher for incidental than for symptomatic tumours: Incidental lesions were significantly lower stage than those that cause symptoms, since For metastatic renal cell carcinoma, factors which may present a poor prognosis include a low Karnofsky performance-status score a standard way of measuring functional impairment in patients with cancer , a low haemoglobin level, a high level of serum lactate dehydrogenase, and a high corrected level of serum calcium.

Renal cell carcinoma is one of the cancers most strongly associated with paraneoplastic syndromes , most often due to ectopic hormone production by the tumour. The cleaned blood is then pumped back into your body. Two needles are inserted for every treatment. The place they are inserted is called the access. A surgeon may connect two of your blood vessels to create an access. This is called a fistula. Connecting the vessels causes the vein to get larger and stronger. The dialysis needles are inserted into that vein. Another option is to connect a plastic tube between two blood vessels. This is called a graft. The needles are inserted into this artificial vein.

In urgent situations, a tube, called a catheter, may be placed temporarily into a large vein in your neck. The tube has two branches, one to carry blood out of the body and the other to return it. Your physician will make a recommendation based on the condition of your veins and other considerations. For dialysis to be successful, you may need to make lifestyle changes, such as following certain dietary recommendations. With supportive care, your symptoms are managed so that you feel better. You may choose supportive care alone or combine it with other treatment options. Without either dialysis or a transplant, kidney failure progresses, eventually leading to death.

In some people, the disease progresses slowly over months and years, while in others the disease progresses quickly. Regenerative medicine holds the potential to fully heal damaged tissues and organs, offering solutions and hope for people who have conditions that today are beyond repair. For people with kidney disease, regenerative medicine approaches may be developed in the future to help slow progression of the disease. Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition.

As part of your treatment for kidney disease, your doctor may recommend a special diet to help support your kidneys and limit the work they must do. Ask your doctor for a referral to a dietitian who can analyze your current diet and suggest ways to make your diet easier on your kidneys. Depending on your situation, kidney function and overall health, your dietitian may recommend that you:. Learning you're in kidney failure may come as a shock, even if you've known about your kidney disease for a while. It may be difficult managing the treatment schedule if you're on dialysis.

For end-stage renal disease, you'll likely continue to see the same doctor and care team you've been seeing for treatment of chronic kidney disease. If you're not already being cared for by a nephrologist — a doctor who specializes in kidney problems — you may be referred to one as your disease progresses. To get ready for your appointment, ask if there's anything you need to do ahead of time, such as limit your diet. Then make a list of:. Take a family member or friend along, if possible. Sometimes it can be hard to remember everything you talked about with your doctor, and a relative or friend may hear something that you missed or forgot. End-stage renal disease care at Mayo Clinic.
