Abstract:
Objective To summarize the clinical features and treatment of male urethral duplication.Methods The clinical data of 2 cases treated in June 2011 and April 2014 were analyzed retrospectively.The first case was a 5-year-old boy presented with passages of urine from two orifices in the penis.The second case was a 15-year-old boy presented with dorsal chordee and a sinus on the dorsum of the penis.The patient had a small amount of watery discharge occasionally dripping out of the opening for 10 years.The 2 patients underwent retrograde urethrography, which revealed a complete duplicated urethra with the channel arising from the proximal prostatic urethra ( class ⅡA2 according to the classification of Effman) .The 2 patients underwent excision of the accessory urethra under general anesthesia.Results The pathology reports of the 2 cases were hyperplasia of squamous epithelium and urothelial mucosa.Pathological diagnosis was urethral duplication.The first case was followed up for 1 year with a satisfactory functional and cosmetic outcome.The second case was followed up for 6 months and no watery discharge noticed from the residual dorsal chordee.Conclusions Urethral duplication is a rare congenital anomality affecting mainly boys.Clinical presentation varies depending on the different anatomical patterns of the urethral anatomy. Surgical management must be evaluated for each different anatomical variation.
