Congenital

There will often be a family history with adult polycystic kidney disease; however, it does not usually present until the third or fourth decade, when the patient may present with an abdominal mass, haematuria, loin pain (infection or bleeding into a cyst) or chronic renal failure. Hypertension may be a presenting symptom. Rarely, hydronephrosis may present at birth. Hydronephrosis in infants may be a cause of failure to thrive.
