緒言

　四重尿管は極めて稀な先天性尿路奇形であり，これまで，1953年にBegg^1），1962年にGotzen^2）による報告をみるのみである。今回，われわれは成人男性で，後部尿道に異所開口を伴つた不完全四重尿管の1例を経験したので，若干の考察を加えて症例報告する。

Complaints and urinalysis were imme-diately improved by anti-biotics administration. X-ray and endoscopic examination revealed no marked change in rt. kidney. However, It. kidney had such anomalies as hypoplastic small kidney, divided four branches of ureter which became one stream, opening to posterior urethra. Left nephro-ureterec-tomy was performed because function of the left kidney was scarce and had recurrent infection caused by reflux.
