Urethral reconstruction for iatrogenic urethral stricture after transurethral prostate surgery: An analysis of surgical and patient-reported outcomes.

Abstract

We investigated the efficacy of urethral reconstruction in male patients with iatrogenic urethral stricture after transurethral prostate surgery. We retrospectively reviewed the cases of 82 patients who underwent urethral reconstruction for iatrogenic urethral stricture caused by transurethral prostate surgery between August 2011 and July 2021. Patients were followed up postoperatively with uroflowmetry, postvoid residual urine measurement, and questionnaires using Peeling's picture score, International Prostate Symptom Score, International Consultation on Incontinence Questionnaire Short Form, Sexual Health Inventory for Men, EuroQol-5 dimensions, and EuroQol-5 dimensions visual analog scores. Successful urethral reconstruction was defined as the absence of a postoperative decrease in urinary force and any additional treatment. The median patient age was 72 years, and the stricture site was the urethral meatus in eight (9.8%) patients, penoscrotal junction in 42 (51.2%), and proximal bulbar urethra in 26 (31.7%). Six patients (7.3%) had synchronous urethral strictures. Urethral reconstruction was successful in 78 patients (95.1%), with a median follow-up of 43 months. The mean maximum flow rate (P < 0.0001), postvoid residual urine (P = 0.004), Peeling's picture score (P < 0.0001), the score for each question and total International Prostate Symptom Score and International Prostate Symptom Score-quality of life scores (P < 0.0001 for all comparisons), and EuroQol-5 dimensions and EuroQol-5 dimensions visual analog scores (P < 0.0001 for both) significantly improved postoperatively. However, the Sexual Health Inventory for Men and International Consultation on Incontinence Questionnaire Short Form scores remained unchanged (P = 0.09 and 0.70, respectively). Urethral reconstruction was effective for urethral stricture due to transurethral prostate surgery in both subjective and objective aspects.
