title: [A case of bilateral ectopic ureter in a male].
abstract: A 7-year-old boy was admitted for recurrent pyelonephritis. Intravenous pyelography IVP showed right hydronephrosis and normal left kidney and ureter. Cystourethroscopy revealed no ureteral orifices in the bladder but bilateral ureteral openings adjacent to the seminal colliculus. Right retrograde pyelography showed severe hydroureter and hydronephrosis. The diagnosis was bilateral ectopic ureteral opening into proximal urethra. His abnormality of ureteral opening was classified as type II in Thom's classification. Bilateral ureterocystoneostomy was performed. Only 3 cases of bilateral ectopic ureter in males have been reported in the Japanese literature.
