POLYCYSTIC KIDNEY DISEASE

Nephrology

POLYCYSTIC KIDNEY DISEASE

1. Autosomal dominant, most common genetic disease of the kidney, associated with a mutation on the short arm of chromosome 16.

2. Onset of polycystic kidney disease occurs at age 20.

3. Clinical - gross/microscopic hematuria (most common), flank pain, CKD, HTN, and cyst infections.

4. Complications - progressive renal failure, HTN, cysts of the kidneys, liver, and pancreas. Associated liver cysts cause hepatomegaly but rarely liver dysfunction. Cerebral aneurysms occur in a very small percent (1-5%).

5. Inx - diagnosis is established when polycystic kidneys are identified on imaging (U/S or CT) during evaluation for hematuria.

6. Screening for aneurysms is recommended only if the patient has 1 or more relatives with a history of SAH or known aneurysm.
