Excision and Primary Anastomosis Reconstruction for Traumatic Strictures of the Pendulous Urethra.

OBJECTIVES

To present a multi-institutional experience with functional and patient-reported outcomes among men undergoing excision and primary anastomosis (EPA) urethroplasty for pendulous urethral strictures.

METHODS

We describe the technique and present our experience with EPA for focal penile strictures. Patients undergoing urethroplasty (2004-2017) at 2 tertiary referral centers were reviewed, of whom 14 (0.7%) underwent EPA of radiographically confirmed pendulous urethral strictures. Validated questionnaires were utilized to evaluate overall improvement (Patient Global Impression of Improvement), urinary bother (International Prostate Symptom Score), and sexual function (International Index of Erectile Function-5). Treatment success was defined as urethral patency without need for subsequent reconstruction.

RESULTS

Among 14 men undergoing penile EPA, 13/14 (93%) had durable treatment success over a median follow-up of 43 months. No patient reported penile curvature postoperatively. Stricture etiology in most cases was posttraumatic (12/14), of which 4 had a history of urethral disruption secondary to penile fracture and 8 iatrogenic trauma. Median age was 51 years (IQR 30-60) and stricture length 1.0 cm (IQR 1.0-1.4). Erectile function was normal in 8/14 patients preoperatively, and postoperative median International Index of Erectile Function was 21. Most men reported significant global improvement in condition (median Patient Global Impression of Improvement 2, IQR 1-3) and most had only mild urinary bother (median International Prostate Symptom Score 4, quality of life 1). The single treatment failure had a history of hypospadias with multiple prior urethral procedures.

CONCLUSION

For men with short strictures of the pendulous urethra, EPA has a high success rate, without adverse sequelae such as erectile function or penile curvature.
