[Rupture of renal pelvis due to urolithiasis: report of two cases].
Two cases of renal pelvis rupture caused by urolithiasis are reported. The first case was in a 62-year-old male who had left flank pain. Urological examination including drip infusion pyelography (DIP) and abdominal computed tomography (CT) revealed a spontaneous rupture of the left renal pelvis. The rupture was assumed to have been caused by a small ureteral stone. The stone passed spontaneously, and the extravasation disappeared with conservative therapy. The second case was in a 84-year-old male who was admitted with high fever. Urological examination including DIP and abdominal CT showed a suspected rupture of the left renal pelvis due to a renal stone at the ureteropelvic junction. Percutaneous nephrostomy was performed and antegrade pyelography showed extravasation from the left renal pelvis. Extravasation disappeared on the 12th postoperative day. Extracorporeal shock wave lithotripsy was performed three times. The renal stone was completely discharged and the nephrostomy tube was removed successfully.
