Spontaneous calyceal rupture caused by a ureteral calculus

Abstract

Rupture of the urinary collecting system with perirenal and retroperitoneal extravasation of the urine is an unusual condition that is typically caused by ureteral-obstructing calculi. We report a case of calyceal rupture with urinoma formation, due to a stone in the distal ureter. The diagnosis was confirmed by computed tomography. Diagnosis, follow-up, and therapeutic approach are discussed.
