[Spontaneous rupture of the renal pelvis: a case report]

A 63-year-old man admitted to our hospital with severe pain in his right flank on June 4, 1987. After admission, his pain increased progressively and he complained of tenderness from the right flank to the right lower quadrant. Computerized tomography and intravenous pyelography demonstrated spontaneous rupture of the right renal pelvis. A retrograde ureteral catheter was indwelling into the right renal pelvis. Because extravasation had disappeared on the retrograde pyelogram, the Catheter was withdrawn after 12 days. After removal of the ureteral catheter, he did not complain of pain. The 42 patients with spontaneous rupture of the renal pelvis reported in the Japanese literature and our one case were discussed.
