Bracka Urethroplasty with Buccal Mucosa Graft: Ergonomic Management of Penile Skin Dartos in the First Stage to Facilitate Second-stage Neourethral Coverage

Abstract

Aims: The aim of the study was to report a new technique of ergonomic penile skin-dartos management during buccal mucosa graft (BMG) to provide adequate penile skin-dartos for neourethral coverage at the time of second-stage tubularization. Materials and Methods: Ten proximal hypospadias with severe chordee underwent first-stage surgery with a new technique. An incision along the urethral plate margin and preputial edge was used to split inner prepuce off preputial dartos and penile degloving leaving inner prepuce attached to corona. Urethral plate was divided into the subfascial plane. Penile dartos was bisected in the dorsal midline. Distal half of penile skin-dartos bifurcated and joined to inner preputial edges. Mobilized and lateralized penile skin-dartos was sutured flanking edges of BMG. The second-stage tubularization after 6 months provided neourethral double dartos coverage with eccentric suture lines. Results: Adequate dartos for neourethral coverage during second-stage tubularization was available in all. Subcoronal urethrocutaneous fistula occurred in one that was repaired. Conclusions: Ergonomic management of inner-preputial skin and ventral transfer of penile skin-dartos helps in providing neourethral coverage during subsequent second-stage tubularization to minimize the occurrence of complications.
