[IIA2-Y-type urethral duplication].

Urethral duplications are extremely rare congenital malformations. The most used classification is that of Effmann and Lebowitz, describing 6 types of urethral duplications. The under type IIA2-Y is one of the most rare duplications corresponding to duplicated urethra originating from the bladder neck and extending toward the ectopic perineal or anal insertion. We here report the case of a 32 year patient, with no previous personal history, suffering from urinary leakage during and after urination since childhood. Clinical examination showed a bottleneck at the level to the perineum initially suggesting urethral fistula. However, the absence of fistula-associated urinary disorders as well as urinary leakage since childhood refuted this assumption. The patient underwent Micturating Retrograde Urethrocistography after perineal orifice catheterization confirming well systematized tract. Surgical exploration was based on excision of the duplicate urethra after hydrophilic catheterization by inserting hydrophilic guidewire up to its anastomosis at the level of the prostate. The examination of the surgical specimen confirmed the diagnosis of supernumerary urethra.
