Polycystic Kidney Disease
Moderate
Polycystic kidney disease is a group of inherited disorders in which numerous fluid-filled cysts develop in the kidneys. The cysts can enlarge the kidneys and, over time, interfere with normal kidney function. Some people have few symptoms for many years, while others develop high blood pressure, abdominal or back discomfort, blood in the urine, kidney stones, or recurrent urinary infections. The condition can progressively reduce kidney function in some individuals. It may also be associated with cysts in other organs and other complications, depending on the type.

When to Seek Medical Attention
Polycystic kidney disease requires ongoing medical monitoring because it can cause high blood pressure, kidney infections, kidney stones, and progressive loss of kidney function. Seek prompt assessment for severe or persistent pain, fever, blood in the urine, markedly reduced urination, or rapidly worsening symptoms. Emergency care is needed for severe pain with fainting, severe breathing difficulty, confusion, or other signs of a serious complication.

Overview
Polycystic kidney disease is a group of inherited disorders in which numerous fluid-filled cysts develop in the kidneys. The cysts can enlarge the kidneys and, over time, interfere with normal kidney function. Some people have few symptoms for many years, while others develop high blood pressure, abdominal or back discomfort, blood in the urine, kidney stones, or recurrent urinary infections. The condition can progressively reduce kidney function in some individuals. It may also be associated with cysts in other organs and other complications, depending on the type.

Causes 1
Polycystic kidney disease is primarily caused by inherited genetic changes. Autosomal dominant polycystic kidney disease is commonly caused by changes in the PKD1 or PKD2 genes and often becomes apparent during adulthood. Autosomal recessive polycystic kidney disease is caused by changes in the PKHD1 gene and commonly presents earlier in life. These genetic changes disrupt proteins involved in normal kidney-cell function and lead to progressive formation and enlargement of cysts. The inheritance pattern and genetic cause influence the age of onset and severity.
Genetics
Risk Factors
Risk depends largely on the inherited form of polycystic kidney disease and family history. People with an affected parent may have a substantial inherited risk in autosomal dominant disease. The condition can affect both sexes. High blood pressure, recurrent urinary problems, and increasing kidney cyst burden may accompany disease progression. Because symptoms may not appear early, individuals with a strong family history may require medical assessment and appropriate monitoring even when they feel well.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Polycystic kidney disease can be evaluated with imaging studies that identify and characterize kidney cysts. Ultrasound is commonly used because it is noninvasive, while CT or MRI may provide more detailed assessment when necessary. A family history can provide important diagnostic information. Genetic testing may be considered when the diagnosis is uncertain, particularly in younger individuals or when family history is unavailable. Kidney function, blood pressure, urine findings, and possible complications are also monitored during evaluation and follow-up.
Prevention
Key Prevention Tips
There is no established way to prevent inherited polycystic kidney disease in someone who carries a disease-causing genetic variant
However, early recognition and regular monitoring can help reduce complications
Controlling blood pressure, avoiding smoking, maintaining appropriate hydration as advised by a clinician, and managing cardiovascular risk factors support kidney health
People with a strong family history may benefit from genetic counseling and appropriate evaluation
Regular monitoring can identify changes in kidney function, cyst burden, or blood pressure that require attention
