Urolithiasis with blind-ending ureteral duplication and azotemia treated with shock wave therapy.

A case of bilateral urolithiasis and renal insufficiency with a blind-ending branch of the right bifid ureter is presented. The diagnosis was made by retrograde ureterogram which revealed a blind-ending branch originating in the middle third of the right ureter. Stones were treated with phased extracorporeal shock wave lithotripsy after preliminary bilateral JJ stenting. The renal parameters reverted to normal and the patient was stone-free.
