What is Renal Cystic Disease?

Renal cystic disease (RCD) is a term used for a group of health issues linked to the development of kidney cysts. Kidney cysts are like little, pouch-like sacs filled with liquid. These issues can show up in both children and adults and may cause symptoms outside the kidneys. The reasons behind these diseases might be inherited (passed down in families) or not. The cysts caused by these diseases are one of the most common kidney abnormalities and can range from not causing any issues to leading to serious kidney disease.

The most common inherited RCD in adults is autosomal dominant polycystic kidney disease (ADPKD), it can also be a part of a group of diseases that affect the liver and kidneys called hepatorenal fibrocystic disease (HRFCD). The most common non-inherited kidney cyst is a simple renal cyst.

Diagnosing renal cystic disease usually involves looking at a variety of factors like the patient’s age, symptoms, kidney function and the features of the cysts such as size, shape, location, and how many there are. The tests for diagnosing this condition may include kidney imaging, lab tests, and genetic testing. The usual way to manage the condition includes supportive care, observing and treating complications, and for some patients, kidney transplantation.

Many people are not familiar with renal cystic disorders. So, it’s important for patients and their families to get enough information and guidance to understand the specific condition diagnosed. This is because some rare kidney cyst syndromes might have genetic implications. Therefore, healthcare professionals should improve their skills in evaluating, managing, and educating patients about renal cystic disease, and they should be encouraged to make positive changes, enhance patient safety, and improve overall care quality. This will help them provide care that is based on evidence and centered around the patient’s needs.

What Causes Renal Cystic Disease?

Renal Cystic Disease (RCD) is a condition that includes many underlying diseases. It can either be inherited, meaning it is passed down through families, or non-inherited, which could be a result of developmental abnormalities, new mutations, or other systemic disorders. Research has led to the advancement of our knowledge about RCD. Nowadays, we understand that some conditions can be categorized as dysplasias, which means there are abnormalities in the kidneys, or ciliopathies, which involve mutations that affect small hair-like structures known as cilia in the kidney tubes. RCD is typically caused by genetic factors and it usually begins in childhood or adolescence, except for ADPKD which is frequently seen in adults.

Inherited Renal Cystic Disease includes Polycystic kidney disease (PKD) which has three types. ADPKD is one of the most common reasons for kidney failure in adults and is caused by mutations in two specific genes called PKD1 and PKD2. These genes produce substances called polycystin-1 and polycystin-2. The PKD1 gene is the most common mutation, occurring in about 85% of patients. Autosomal recessive polycystic kidney disease (ARPKD) is a rare condition caused by a mutation in the PKHD1 gene that leads to abnormalities in the kidneys and liver. It is associated with high early newborn mortality rate because of underdeveloped lungs and is linked with developmental issues in the liver and high blood pressure. Glomerulocystic kidney disease is usually found in newborns and infants who have a family history of PKD, but not all cases are associated with mutations in the PKD1 or PKD2 genes. This condition is associated with cyst formation in the kidney’s filtering units (the glomerulus) and increased space within the Bowman’s capsule due to gene mutations in renal tubular primary cilia.

Nephronophthisis is a rare, inherited disorder that can affect individuals at any age but is mostly observed in children and young adults, leading to end-stage kidney failure before age 30. Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a group of rare genetic disorders which have been recently reclassified due to mutations in various genes. Tumors syndromes: These cysts result from inherited gene mutations that exhibit variable severity. Noninherited RCDs can be due to developmental abnormalities in the kidneys, new genetic mutations, or acquired cysts from systemic disease. These are associated typically with issues in the development of the kidneys. Conditions under noninherited are Acquired cystic disease, Simple renal cysts, Multicystic dysplastic kidney, Medullary sponge kidney, and others are considered abnormalities.

Acquired cystic disease occurs in patients requiring dialysis and manifests as shrunken kidneys with tiny cysts, primarily linked to the length of dialysis. Simple renal cysts usually develop after the age of 20 years and increase with age. The cause of these simple cysts is usually high blood pressure. Multicystic dysplastic kidney is a condition that occurs during fetal development when the kidney’s filtering units and tubes do not develop correctly in one or both kidneys. Medullary sponge kidney is characterized by the dilation of the kidney tubes, kidney cysts, and kidney stones. There are also rare abnormalities that lead to renal cysts, including pyelocaliceal diverticula, unilateral renal cystic disease, and multilocular renal cystic nephroma.

Risk Factors and Frequency for Renal Cystic Disease

The occurrence of RCD, or Renal Cystic Disease, varies depending on the root cause. Several different issues can cause RCD, including Polycystic Kidney Disease, Nephronophthisis, and Autosomal-dominant tubulointerstitial kidney disease.

  • Polycystic Kidney Disease: The most prevalent form of RCD is ADPKD, affecting around 12.5 million people globally. About half of these persons develop kidney failure by age 70. ARPKD, another form of Polycystic Kidney Disease, is rarer and more severe, affecting 1 in 20,000 infants and resulting in a high mortality rate.
  • Nephronophthisis: This rare genetic disorder affects around 98.3 children per million births. Chronic renal failure is a common complication, causing 1% to 5% of all affected patients to need dialysis or transplantation.
  • Autosomal-dominant tubulointerstitial kidney disease: This condition has a population prevalence of 9 in 1 million births, usually resulting in renal failure between the ages of 30 and 60.
  • Cysts related to tumor syndromes: These conditions occur due to certain genetic mutations, with an incidence range from 1 in 6,000 to 1 in 10,000 births.
  • Acquired cystic disease: This kind of renal cysts is due to dialysis and is more common in males.
  • Simple renal cysts: These generally develop in adults after the age of 20 and are more common in men, those with high blood pressure, and the elderly.
  • Multicystic dysplastic kidney: A higher incidence is observed in unilateral variants, estimated at 1 per 4300 births.
  • Medullary sponge kidney: This type is not well documented. Nonetheless, somewhere between 3% and 20% of people with kidney stones are thought to have it.
  • Rare miscellaneous abnormalities: These occurrences are infrequent; for instance, pyelocaliceal diverticula are found in up to 0.6% of patients who have had specific kidney x-rays.

Signs and Symptoms of Renal Cystic Disease

Renal cystic disease (RCD) often shows up because of symptoms in patients but needs diagnostic studies to establish a diagnosis. The kind of symptoms seen can vary widely and could range from no symptoms to end-stage renal disease (ESRD). Some conditions within RCD can show particular symptoms related to organs other than the kidneys, and a detailed family history can be crucial for diagnosis. There are numerous causes of RCD, each with different symptoms:

  • Autosomal-dominant polycystic kidney disease (ADPKD): People with this condition usually don’t show symptoms until they’re between 30 and 50 years old. However, children with ADPKD may have higher rates of protein in their urine and high blood pressure compared to children without this condition. Adults with ADPKD might have side pain, blood in the urine, bleeding cysts, high blood pressure, and chronic kidney failure. Furthermore, a quarter of patients with ADPKD can develop kidney stones. ADPKD can also cause symptoms in other parts of the body, such as liver cysts, a swollen liver, cysts in the pancreas, diverticulosis, heart valve disease, cerebral aneurysms, and cysts in the seminal vesicles. Family history can aid in diagnosing ADPKD, as between 75% and 90% of patients with ADPKD also have a parent with this diagnosis.
  • Autosomal recessive polycystic kidney disease (ARPKD): Symptoms often appear in unborn babies, newborns, or early adults. Patients also show liver disease which can lead to a range of complications. Other symptoms include hypertension, long-term survivors might require liver transplantation, and symptoms associated with newborns like anhydramnios and feeding difficulty due to enlarged kidneys.
  • Autosomal-dominant tubulointerstitial kidney disease (ADTKD): Symptoms of this condition include excessive thirst and urination. We see normal blood pressure, and renal failure progresses slowly, leading to ESRD at a median age of 45. The presence of the UMOD gene is associated with high uric acid levels and gout.
  • Nephronophthisis: Patients with this condition typically show symptoms of ESRD by the age of 30 years. Other symptoms might include growth retardation, excessive thirst and urination, anemia, and progressive kidney failure.
  • Tuberous sclerosis: This condition leads to benign tumor formation throughout the body. Patients can show several characteristic findings, including benign skin tumors, epilepsy, and intellectual disability.
  • Von Hippel-Lindau syndrome: This condition can cause cysts in the kidneys and other organs. Diagnosis varies based on family history.
  • Acquired renal cystic disease: Patients on dialysis usually progress without showing symptoms; however, it may present with a kidney mass that can be felt, gross blood in the urine, flank pain, urinary tract infection, or kidney colic.
  • Multicystic dysplastic kidney: Patients with this condition are often identified during antenatal screening. Children with this condition are more likely to have urinary tract infections. In most children, the cysts will disappear on their own and leave no residual symptoms.
  • Simple renal cysts: These cysts usually produce no symptoms and have no family history of kidney dysfunction. However, if the cysts are large, they can cause pain, blood in the urine, or infection.

Testing for Renal Cystic Disease

Doctors use a blend of diagnostic techniques and tests to identify Renal Cystic Disease (RCD)—a condition that causes fluid-filled sacs to form in the kidneys. If you have unusual symptoms of RCD or no known family history of this condition, your doctor might use imaging studies and sometimes genetic tests. They might also carry out other laboratory tests to help them understand your diagnosis better and rule out similar diseases.

Kidney ultrasound is commonly used to diagnose RCD. This method is preferred when patients report symptoms like flank pain, high blood pressure, or frequent urinary tract infections. Patients might also have a kidney ultrasound if renal cysts have been picked up in prenatal ultrasounds or they have a family history of polycystic kidney disease and are over 18 years old. Ultrasound can also efficiently track the development of the disease.

Sometimes more specific imaging techniques, like CT scans or MRIs, are used to get a more detailed picture of the kidneys, especially if the ultrasound results are inconclusive. These scans are excellent at highlighting cyst properties and how the disease is progressing.

There’s a special system called the Bosniak classification, which doctors use to interpret CT scan results. This system categorizes cysts into five groups depending on their potential to turn into cancer. This classification helps doctors decide the best way to manage your health—whether that’s through monitoring, surgery, or other treatments.

In some cases, genetic testing may be useful to identify any hereditary cause behind RCD. However, it’s important to understand that genetic testing might not identify all possible hereditary causes since new mutations might not be included in current testing. If your doctor suspects RCD during pregnancy, prenatal genetic testing might be recommended.

Lastly, laboratory tests help to examine kidney function or detect complications of RCD, such as liver disease. For instance, in those with ADPKD (a type of polycystic kidney disease), tests might denote abnormal levels of specific proteins and cells in the urine, which indicates abnormal kidney function. Also, urine cultures help detect infection. If bacteria are found in the urine, it could mean an infected renal cyst.

In conclusion, the diagnosis of RCD uses a combination of imaging studies, genetic tests, and laboratory tests. Your doctor will use these tools to accurately diagnose and manage your condition.

Treatment Options for Renal Cystic Disease

The treatment for RCDs (renal cystic diseases), which are diseases that cause small, fluid-filled sacs or cysts to form in the kidneys, is usually supportive. This means that we focus on controlling any related issues such as high blood pressure, infection, and pain that can come with these diseases. High blood pressure, for instance, is almost always found in patients with a type of RCD called polycystic kidney disease. There are different options to manage this, including certain types of blood pressure medication like angiotensin receptor blockers, angiotensin-converting enzyme inhibitors, and calcium channel blockers. Even though these can help, many patients will need more than one kind of medication to control their blood pressure effectively. Keeping blood pressure in check may help slow down the progression of kidney disease.

If you have Autosomal Dominant Polycystic Kidney Disease (ADPKD), a type of polycystic kidney disease that is inherited from one parent, you might also be advised to drink plenty of water to help naturally limit the formation and growth of cysts. You could also be advised to limit the amount of salt in your diet, exercise regularly, maintain a healthy weight, and manage any high blood pressure.

Medication like tolvaptan, which works by blocking a hormone that can stimulate the growth of renal cysts, has been shown to slow the progress of the disease. It’s especially useful for younger patients with earlier stages or those with fast-progressing disease, but is less effective in those over 55. However, tolvaptan can cause liver damage and requires regular monitoring of liver function tests. Other side effects like increased urination and severe thirst can also occur.

Infections in the cysts can be treated with certain antibiotics, and pain can be managed with methods like antidepressants or referral to a pain management specialist. There are other types of RCDs, such as Autosomal Recessive Polycystic Kidney Disease (ARPKD), which is inherited from both parents, and Tuberous Sclerosis Syndrome, which can cause non-cancerous tumors to grow in many parts of the body including the kidneys. The treatment recommendations for these conditions are different and generally target the specific symptoms and complications of these diseases.

Treatment for RCDs associated with the Von Hippel-Lindau Syndrome or Nephronophthisis and Autosomal-Dominant Tubulointerstitial Kidney Disease is based on symptom management. For example, in the latter case, recommendations may include salt supplementation for severe salt wasting and avoidance of certain medications. Specific treatments for symptoms or complications such as high uric acid levels or end-stage renal disease are also available.

Acquired Cystic Renal Disease, which develops as a result of long term kidney damage, and Simple Renal Cysts are other types of RCDs that require regular monitoring due to the increased risk of complications like bleeding and kidney cancer. In some cases, surgical intervention may be needed.

There are also ongoing studies investigating new treatments for genetic renal cystic diseases. Certain drugs are currently in animal studies or clinical trials to test their effectiveness in these diseases. Some of these drugs aim to control cell growth, while others aim to reduce fluid secretion and cell proliferation, or affect calcium signaling. However, more research is needed before these can be recommended for use in humans.

To make an accurate diagnosis, it’s crucial to rule out other similar conditions. This allows doctors to provide the best, most targeted treatment available. A full health history review, physical exam for additional findings, various imaging techniques, and genetic testing can all help to distinguish between the different causes of kidney cysts. Some conditions that might look like kidney cyst are:

  • Angiomyolipomas (benign tumors in the kidneys)
  • Cystic kidney tumors
  • Extrarenal pelvis (a normal variation where the kidney’s pelvis is located outside the kidney)
  • Hemangiomas (clusters of blood vessels)
  • Hydronephrosis (swelling of a kidney due to a build-up of urine)
  • Nephrolithiasis (kidney stones)
  • Neuroblastoma (a type of cancer often found in the adrenal glands)
  • Parapelvic renal cysts (cysts near the kidney pelvis)
  • Kidney abscess (a pocket of pus in the kidney)
  • Renal dysplasia (impairment of kidney development)
  • Lipomas (benign fatty tumors)
  • Various rare genetic disorders

What to expect with Renal Cystic Disease

The outlook for patients with kidney diseases that create cysts (bubble-like sacs filled with fluid) depends on how quickly their kidney function declines and whether they have other health issues too. Younger patients who advance to End-Stage Renal Disease (a serious kidney condition that needs dialysis or a transplant) generally have a worse outlook.

Take the example of a condition called Autosomal Dominant Polycystic Kidney Disease (ADPKD). People over 30 with ADPKD typically start experiencing some kidney problems. By age 60, about 35% to 45% of patients with ADPKD will develop end-stage renal failure; by age 70, the number goes up to 50%; and it goes up to 75% by age 75. In patients over 40, the Glomerular Filtration Rate (a test to measure how well the kidneys are working) with ADPKD decreases by about 5 mL per minute each year. The most reliable way to predict whether the disease will turn into end-stage renal failure seems to be measuring the size of the kidneys and cysts. Other signs of a faster progression and worse outlook include:

– Black ethnicity or genetic heritage
– Diagnosis at an earlier age
– Diabetes
– Blood in urine
– High blood pressure
– Larger kidneys and cyst size
– Being male
– ADPKD-subtype PKD1
– Rapidly growing kidneys or cysts
– Sickle cell trait
– Increasing amounts of protein in urine

ADPKD does not increase the chances of getting kidney cancer, but if you do, the cancer is more likely to be in both kidneys, which is uncommon. Kidney cancer rarely causes death under these circumstances. Common causes of death in these cases are heart valve disease, widespread infection, kidney damage from hypertension, kidney failure, or stroke from ruptured blood vessels in the brain due to the combination of cerebral aneurysms and high blood pressure. Liver cysts are common, but they frequently have no symptoms.

For Autosomal Recessive Polycystic Kidney Disease (ARPKD), underdeveloped and immature lungs cause most of the problems in newborns, often needing a mechanical ventilator. Newborns may also develop high blood pressure in the liver, which leads to spleen enlargement and low platelet count. Apart from kidney failure, common causes of death include respiratory weaknesses and liver diseases. Kidney and liver transplantations at a young age can lead to longer survival rates.

Possible Complications When Diagnosed with Renal Cystic Disease

There are several complications associated with ADPKD, such as high blood pressure, kidney failure, infection of kidney cysts, severe pain in the belly and side, and bleeding in the space surrounding the brain. Respiratory distress, or difficulty breathing, due to underdeveloped lungs is the most common complication of another variant of the disease, ARPKD. Other complications of ARPKD may include high blood pressure in the liver, bleeding from dilated veins, and kidney inability.

Nephronophthisis, another kidney disease, could be associated with both liver and other complications outside the kidney, like liver fibrosis (scarring), enlargement of bile ducts, growth lag, eye conditions, a condition involving underdeveloped part of the brain, disorders related to eye movement, and abnormal development of skeletons.

ADTKD is another kidney disease whose complications depend on the specific genetic mutation associated with the disease that may include having excess acid in the blood, a form of arthritis, low sodium in blood, and excessive urination.

Common Complications:

  • High blood pressure
  • Kidney failure
  • Infection in kidney cysts
  • Severe abdominal and flank pain
  • Bleeding in the brain’s surrounding space
  • Difficulty breathing
  • High liver blood pressure
  • Bleeding from dilated veins
  • Kidney dysfunction
  • Liver scarring
  • Enlargement of bile ducts
  • Growth lag
  • Eye disease
  • Brain underdevelopment
  • Eye movement disorders
  • Abnormal development of skeletons
  • Excess acid in the blood
  • Form of arthritis
  • Low sodium levels in the blood
  • Excessive urination

Preventing Renal Cystic Disease

If you or a family member has been diagnosed with genetic kidney diseases like ADPKD or ARPKD, getting genetic counseling is extremely important. Genetic counseling is a service that provides information and support to people who have or may be at risk for genetic diseases. Also, knowing how to adjust your lifestyle can help lessen the impact of these diseases.

Some suggestions include seeing your doctor regularly, cutting down on salt in your diet, controlling high blood pressure, maintaining a healthy body mass index (BMI), staying hydrated, and exercising regularly. These modifications can help manage your symptoms and improve your overall health.

Frequently asked questions

The prognosis for Renal Cystic Disease depends on various factors such as the specific type of cystic disease, the rate of kidney function decline, and the presence of other health issues. In general, younger patients who progress to End-Stage Renal Disease (ESRD) tend to have a worse prognosis. For example, in Autosomal Dominant Polycystic Kidney Disease (ADPKD), the likelihood of developing end-stage renal failure increases with age, with around 35-45% of patients developing it by age 60 and up to 75% by age 75. Other factors that may indicate a faster progression and worse prognosis include black ethnicity, earlier diagnosis, diabetes, blood in urine, high blood pressure, larger kidneys and cyst size, being male, and increasing amounts of protein in urine.

Renal Cystic Disease can be either inherited or non-inherited. Inherited cases can be caused by genetic factors and are usually present from childhood or adolescence. Non-inherited cases can be due to developmental abnormalities, new genetic mutations, or acquired cysts from systemic diseases.

The signs and symptoms of Renal Cystic Disease can vary depending on the specific condition within RCD. Some common signs and symptoms include: - No symptoms: In some cases, Renal Cystic Disease may not cause any noticeable symptoms. - End-stage renal disease (ESRD): This is a severe form of kidney disease that can result from Renal Cystic Disease. - Protein in the urine: Children with Autosomal-dominant polycystic kidney disease (ADPKD) may have higher rates of protein in their urine. - High blood pressure: Both children and adults with ADPKD may experience high blood pressure. - Side pain: Adults with ADPKD might experience pain on the side of their body. - Blood in the urine: ADPKD can cause blood to appear in the urine. - Bleeding cysts: In some cases of ADPKD, the cysts in the kidneys may bleed. - Chronic kidney failure: ADPKD can lead to chronic kidney failure. - Kidney stones: Approximately a quarter of patients with ADPKD may develop kidney stones. - Symptoms in other organs: ADPKD can cause symptoms in other parts of the body, such as liver cysts, a swollen liver, cysts in the pancreas, diverticulosis, heart valve disease, cerebral aneurysms, and cysts in the seminal vesicles. - Liver disease: Patients with Autosomal recessive polycystic kidney disease (ARPKD) often show symptoms of liver disease. - Hypertension: ARPKD can also cause hypertension. - Enlarged kidneys: Newborns with ARPKD may have enlarged kidneys, leading to symptoms such as anhydramnios and feeding difficulty. - Excessive thirst and urination: Autosomal-dominant tubulointerstitial kidney disease (ADTKD) can cause excessive thirst and urination. - Normal blood pressure: ADTKD is associated with normal blood pressure. - Slow progression of renal failure: ADTKD leads to end-stage renal disease (ESRD) at a median age of 45. - High uric acid levels and gout: The presence of the UMOD gene in ADTKD is associated with high uric acid levels and gout. - Growth retardation: Nephronophthisis can cause growth retardation in addition to symptoms of ESRD. - Anemia: Nephronophthisis can also lead to anemia. - Benign tumor formation: Tuberous sclerosis can cause benign tumor formation throughout the body. - Characteristic findings: Patients with tuberous sclerosis may have benign skin tumors, epilepsy, and intellectual disability. - Cysts in multiple organs: Von Hippel-Lindau syndrome can cause cysts in the kidneys and other organs. - Acquired renal cystic disease: Patients on dialysis may not show symptoms, but it can present with a kidney mass, blood in the urine, flank pain, urinary tract infection, or kidney colic. - Identified during antenatal screening: Multicystic dysplastic kidney is often identified during antenatal screening. - Urinary tract infections: Children with multicystic dysplastic kidney are more likely to have urinary tract infections. - Simple renal cysts: These cysts usually do not produce symptoms, but if they are large, they can cause pain, blood in the urine, or infection.

The types of tests that are needed for Renal Cystic Disease (RCD) include: 1. Imaging studies: - Kidney ultrasound: commonly used to diagnose RCD and track the development of the disease. - CT scans or MRIs: used to get a more detailed picture of the kidneys, especially if ultrasound results are inconclusive. - Bosniak classification: a system used to interpret CT scan results and categorize cysts based on their potential to turn into cancer. 2. Genetic tests: - Genetic testing may be useful to identify any hereditary cause behind RCD, although it may not identify all possible hereditary causes. - Prenatal genetic testing might be recommended if RCD is suspected during pregnancy. 3. Laboratory tests: - Urine tests: help examine kidney function and detect complications of RCD, such as abnormal levels of specific proteins and cells in the urine. - Urine cultures: help detect infection, especially if bacteria are found in the urine, indicating an infected renal cyst. - Other laboratory tests may be carried out to better understand the diagnosis and rule out similar diseases, such as liver disease. These tests are used in combination to accurately diagnose and manage RCD.

The doctor needs to rule out the following conditions when diagnosing Renal Cystic Disease: - Angiomyolipomas (benign tumors in the kidneys) - Cystic kidney tumors - Extrarenal pelvis (a normal variation where the kidney's pelvis is located outside the kidney) - Hemangiomas (clusters of blood vessels) - Hydronephrosis (swelling of a kidney due to a build-up of urine) - Nephrolithiasis (kidney stones) - Neuroblastoma (a type of cancer often found in the adrenal glands) - Parapelvic renal cysts (cysts near the kidney pelvis) - Kidney abscess (a pocket of pus in the kidney) - Renal dysplasia (impairment of kidney development) - Lipomas (benign fatty tumors) - Various rare genetic disorders

When treating Renal Cystic Disease, there can be several side effects. These include liver damage, increased urination, severe thirst, and potential complications such as bleeding and kidney cancer. Additionally, medication like tolvaptan, which is used to slow the progress of the disease, requires regular monitoring of liver function tests.

You should see a nephrologist for Renal Cystic Disease.

The occurrence of Renal Cystic Disease varies depending on the root cause, with different forms of the disease having different prevalence rates.

The treatment for Renal Cystic Diseases (RCDs) is usually supportive, focusing on controlling related issues such as high blood pressure, infection, and pain. Medications like angiotensin receptor blockers, angiotensin-converting enzyme inhibitors, and calcium channel blockers can be used to manage high blood pressure. For Autosomal Dominant Polycystic Kidney Disease (ADPKD), drinking plenty of water, limiting salt intake, exercising regularly, maintaining a healthy weight, and managing high blood pressure are advised. Tolvaptan, a medication that blocks a hormone stimulating cyst growth, can slow the progression of the disease, but it can cause liver damage and has side effects like increased urination and severe thirst. Infections in the cysts can be treated with antibiotics, and pain can be managed with antidepressants or referral to a pain management specialist. Treatment for other types of RCDs varies based on specific symptoms and complications. Regular monitoring and surgical intervention may be necessary in some cases. Ongoing studies are investigating new treatments for genetic renal cystic diseases.

Renal cystic disease is a group of health issues characterized by the development of kidney cysts, which are small sacs filled with liquid. These issues can occur in both children and adults and may cause symptoms outside the kidneys. The causes of renal cystic disease can be inherited or non-inherited, and the cysts can range from being asymptomatic to leading to serious kidney disease.
