The patient, a man aged 23 years, visited our department for the examination of urinary tract and ejaculative dificiens. DIPs showed right incomplete double renal pelvis and ureter with right hydroureter. At cystoscopy, the right half of the trigone was hypoplastic and right ureter orifice was absent. The orifice of right ureter opened in the posterior urethra. Internal urethral orifice was widely opened. The right ureteral pressure-flow study showed no obstruction. And, retrograde ejaculation was found to be due to regurgitate of the semen into the bladder.
