異所性尿管瘤の1例

Abstract

A case of ectopic ureterocele was reported. An eight-months-old girl was admitted to the Osaka Medical College Hospital on December 4th, 1976 with complaints of urinary tract infection and urinary retention. Excretory pyelography showed hydronephrosis on the right and non-functioning kidney on the left, and a large filling defect in the bladder which was later diagnosed as a large ureterocele by the cystoscopic examination. A complete duplication of the ureter with ectopic ureterocele on the left side was found at operation. She underwent complete removal of the ectopic ureterocele with left nephrectomy and ureterectomy. Although many series of patients with ectopic ureterocele have been reported in foreign literatures, only twenty-three such cases have been reported in Japan which were reviewed in this paper.
