A new biaxial epilated scrotal flap for reconstructive urethral surgery.

PURPOSE We describe a new type of perineum based scrotal flap with biaxial vascularization supplied by both superficial perineal arteries. Flap length of up to 20 cm. may be attained for urethral reconstruction. MATERIALS AND METHODS A total of 37 men with complex urethral stenosis of different etiologies underwent surgery using 1 of 3 urethroplasty techniques based on this new flap. The whole anterior urethra, including pendulous and bulbar segments, was reconstructed with a scrotal patch in 10 patients. A scrotal tubular flap was used as a substitute for the bulbar urethra in 7 patients and for the membranous portion in 4. Bulbar urethroplasty with a scrotal island patch was performed in 16 patients. RESULTS Of the patients 86% achieved normal voiding after 1-stage urethroplasty. Mean followup was 39.5 months. CONCLUSIONS The excellent axial vascularization of this new flap permits successful resolution of the most complex urethral stenoses regardless of extension, location and etiology.
