Q61.2
Polycystic kidney, adult type
Clinical Classification Guidelines
Inclusion Terms
- Polycystic kidney, autosomal dominant
Medical Intelligence & Overview
Polycystic Kidney Disease (PKD), adult type, also known as autosomal dominant polycystic kidney disease (ADPKD), is a genetic disorder characterized by the growth of multiple cysts in the kidneys. These fluid-filled cysts can enlarge the kidneys and impair their function over time. It is one of the most common inherited kidney disorders, often manifesting symptoms in adulthood, typically between the ages of 30 and 50. While it primarily affects the kidneys, PKD can also involve other organs, leading to a variety of health issues.
Causes & Symptoms
Clinical Causes: Genetic mutations in specific genes (PKD1 or PKD2) that are inherited from one parent. Autosomal dominant pattern, meaning only one copy of the mutated gene is sufficient to cause the disorder. Family history of PKD increases the risk of developing the condition. New mutations can occur spontaneously, though this is less common.
Key Symptoms: Pain or tenderness in the back or sides. Blood in the urine (hematuria). Increased size of the abdomen due to enlarged kidneys. Frequent urinary tract infections. High blood pressure (hypertension). Kidney stones. Progressive decline in kidney function leading to fatigue, swelling, or other signs of kidney failure.
Diagnostic & Treatment
Diagnosis Path: Ultrasound imaging to detect cysts in the kidneys. CT scans or MRI scans for a more detailed view, especially in cases with unclear ultrasound results. Blood tests to evaluate kidney function, including serum creatinine and glomerular filtration rate (GFR). Genetic testing to identify mutations in PKD genes, especially in unclear cases or for family planning purposes.
Treatment Protocols: Blood pressure control with medications such as ACE inhibitors or ARBs. Pain management strategies. Addressing urinary tract infections promptly with antibiotics. Maintaining adequate hydration to reduce kidney stone risk. Dietary modifications, including reduced salt intake. Monitoring kidney function regularly. In advanced cases, preparing for dialysis or kidney transplantation may be necessary.
