Complete Diphallia: Rare presentation to single‐stage surgical success

Le résumé fourni par la source

Abstract Diphallia is an extremely rare congenital anomaly characterized by penile duplication. Fewer than 100 cases have been reported in the literature. The condition presents with a wide spectrum of anatomical variations, often necessitating individualized surgical strategies. We present the case of a young adult male presenting with complete diphallia, bladder and urethral duplication and proximal hypospadias. Evaluation revealed two fully developed penises located side‐by‐side, each with independent corpora cavernosa and a corpus spongiosum. Imaging confirmed two separate urinary bladders and bilateral grade 2 vesico‐ureteric reflux. The patient underwent a single‐stage reconstruction involving the excision of the left phallus, proximal urethro‐urethrostomy and distal neourethral construction using a tubularized skin flap with a tunica vaginalis interposition layer. Postoperative recovery was uneventful, yielding favorable cosmetic and functional outcomes, including normal urinary flow and preserved erectile function. This case underscores the efficacy of single‐stage reconstruction in complex diphallia and contributes to the existing literature on embryological theories and surgical classification.
