Abstract:
Objective To describe a novel surgical technique for male long-segment urethral stric- ture after pelvic trauma using the intact and pedieled pendulous urethra to replace the bulbar and membra- nous urethra,and then reconstructing anterior urethra.Methods Three patients with long-segment post- traumatic bulbar and membranous urethral strictures with short left pendulous urethras who had undergone several failed previous surgeries were treated with staged pendulous-prostatic anastomotic urethroplasty fol- lowed by reconstruction of the anterior urethra.This procedure was divided into 3 stages.The first-stage sur- gery was mobilization of anterior urethra down to the coronary sulcus and then re-routing the prostatic urethra followed by pendulous-prostatic anastomotic urethroplasty with transposition of penis to perineum.The sec- ond-stage surgery was transecting the anterior urethra at the site of coronary sulcus 6 months later when it was re-vaseularized,then straightening the penis and performing urethroperineostomy.The third-stage surgery was reconstruction of anterior urethra 6 months later.Results Case 1 reported satisfactory voiding postopera- tively.Retrograde urethrography showed that the urethra was patent with no post-voiding residual urine (PVR),and bilateral vesicoureteral reflux almost disappeared.The Qmax was 18.8ml/s,and 18ml/s after the third stage surgery and at 2-year follow-up.Case 2 also had satisfactory voiding.A 22F urethral catheter could smoothly pass through the urethra,and Qmax was 19.5 ml/s with no PVR at 2-year follow-up.Case 3 underwent the first stage surgery through perineal and pubic routes.The urethrorectal and urethroperineal fis- tulas were excised and repaired simultaneously.After operation the fistulas healed,but the stenostomia resul- ting from wound infection needed further treatment.Conclusions This procedure is effective for men with complex long-segment post-traumatic bulbar and membranous urethral strictures,especially for those undergo- ing failed previous surgical treatment.
