Ureteropelvic junction obstruction in association with autosomal dominant polycystic kidney disease: a case report in a trauma patient.

Autosomal dominant polycystic kidney disease (ADPKD) is a common cause of cystic renal disease and can predispose to renal insufficiency. Although typically diagnosed and discussed in the pediatric population, ureteropelvic junction obstruction may also make patients prone to renal dysfunction and failure. These two disease processes can coexist in the same patient, which may, in turn, complicate their management. We present the case of an adult patient with known ADPKD who suffered a traumatic fall and subsequent retroperitoneal bleed, and was also diagnosed with a UPJ obstruction of the left kidney on the basis of pathological analysis of the specimen at the time of nephrectomy.
