Evaluation of the efficacy of perineal urethrostomy for patients with anterior urethral stricture: insights from surgical and patient-reported outcomes

Abstract

Purpose

To examine the efficacy of perineal urethrostomy (PU) in patients with anterior urethral stricture.

Methods

Patients who underwent PU for anterior urethral stricture between 2013 and 2020 were retrospectively reviewed (n = 56). Surgical success was defined as no need for additional intervention. Uroflowmetry and measurement of residual urine volume (PVR) were examined postoperatively, and the patients were asked to fill out sexual health inventory for men (SHIM) and the validated Urethral Stricture Surgery Patient-reported Outcome Measure questionnaires before and after PU. The overall patient satisfaction was also assessed.

Results

PU was successful in 92.9% of patients (n = 52), with a median follow-up of 34 months. Two of four were salvaged by re-do PU, and one was salvaged by forming a composite stoma using a penile skin graft. Thirty-nine patients (69.6%) filled out the questionnaires 6 months after surgery. The mean maximum flow rate, PVR, lower urinary tract symptoms (LUTS)-total score, LUTS-specific quality of life, and EuroQol-visual analog scale scores improved significantly from 3.8 mL/s, 77.6 mL, 12.9, 2.6, and 53.6 at baseline to 17.6 mL/s, 21.3 mL, 4.1, 0.9, and 74.9 postoperatively (p = 0.003, p = 0.004, p = 0.005, p < 0.0001, p < 0.0001, respectively). The SHIM score did not change significantly (from 2.6 at baseline to 2.3 postoperatively; p = 0.59). As for patient satisfaction, 84.6% of patients (33/39) were “satisfied” (46.1%) or “very satisfied” (38.5%) with the outcome.

Conclusions

PU had a high surgical success rate, and significantly improved patients’ subjective symptoms and achieved a high level of satisfaction.
