Congenital Megaprepuce: Surgical Approach

Abstract

To describe surgical procedure and results of Congenital Megaprepuce (CMP) that consists in phimosis and megaprepuce; glans and corpora trapped into pre-pubic fat; incomplete micturition with typical "ballooning" aspect. Genitoplasty with penoscrotal separation (GPS) was performed at Pediatric Surgery Department of Hospital Nord - Marseille, between July and December 2010, in 5 uncircumcised children with CMP, by the same surgeon. Transversal incision at the ventral penoscrotal junction was used, with shaft bipartition and Buck's ventral fascia exposition. The inner layer of prepuce was resected while the outer layer was preserved for coverture of the penile shaft. The dorsal foreskin was medially and longitudinally incised to obtain adequate length of the dorsal shaft. The first middle dorsal suture was made using PDS 6.0 and completed in ventral direction with interrupted stitches. The urinary catheter was placed and hydrocolloid duoderm dressing used. Perioperative prophylactic antibiotic was given and pain control achieved with paracetamol and codeine. All patients presented urinary troubles before surgery. Skin penile coverage was complete in all patients with cosmetically and functionally satisfying results; no complication was observed at 12 months mean follow-up. CMP is a specific entity of "inconsistent penis." Surgical treatment should be discussed at diagnosis, resolving micturition troubles. GPS is a simple and reproducible procedure by experienced surgeons. Excellent cosmetic and functional results are obtained at mean follow-up, even if long-term results are required. GPS can be useful in other malformations of the penile shaft.
