10例を経験したが6例は尿管結石に起因するものであり,他の4例は悪性腫瘍によるものであった.後者の場合,予後は不良であり診断及び治療に特別な配慮が必要であると思われたWe herein report 10 patients with spontaneous peripelvic extravasation. They were 7 males and 3 females, ranging in age from 39 to 78 years old. The spontaneous peripelvic extravasation were caused by ureteral stones in 6 patients, and by invasion of malignant tumors in 4 patients (2 gastric cancer, 1 prostatic cancer, 1 uterine cancer). In all patients with ureteral stones, the extravasation disappeared following conservative therapy or double J stent placement. In the cases of malignant tumors, nephrostomy or double J stent placement were needed for treatment of the extravasation and their prognosis were very poor.
