Rupture of the renal pelvis is infrequently found on intravenous urography (IVU) and associated with obstructive uropathy with a sudden increase in intrapelvic pressure. Though any etiology of obstruction may cause rupture of the renal pelvis, ureteric calculus is a frequent occurrence. We experienced a case of bladder transitional cell carcinoma (TCC) with obstructive uropathy and rupture of the renal pelvis. The retroperitoneal extravasation was depicted clearly on computed tomography (CT). We discuss the clinical course and present the imaging findings (IVU and CT) of rupture of the renal pelvis.
