title: [A case of spontaneous peripelvic extravasation associated with ureteral stenosis caused by retroperitoneal lymph node metastasis of ascending colon cancer].
abstract: A case of spontaneous peripelvic extravasation associated with ureteral stenosis caused by retroperitoneal lymph node metastasis of the ascending colon cancer is reported. A 47-year-old woman complained of colic on right costa-vertebral angle. Excretory urograms showed right peripelvic extravasation and CT-scan showed urinoma formation around right kidney. Subsequent examination of right retrograde pyelo-ureterograms showed ureteral stenosis at sacro-iliac region. Operative findings revealed ureteral stenosis caused by retroperitoneal lymph node metastasis of ascending colon cancer, which was regarded as inoperable. There are a few reports of spontaneous peripelvic extravasation caused by a malignant tumor in Japanese literature. Twenty of them are reviewed.
