Outcomes of Double-Face Buccal Mucosal Urethroplasty for Treating Anterior Urethral Stricture in Adult Males.

Abstract

Objective: To assess the results of double-face buccal mucosal graft urethroplasty (BMG) for treating anterior urethral stricture in adult males.

Study design: An observational study. Place and Duration of the Study: Department of Urology, Sindh Institute of Urology and Transplantation, Karachi, Pakistan, from 2021 to 2022.

Methodology: The inclusion criteria were adult males, aged 15 to 70 years, with a previous surgical procedure for hypospadias and the presence of long penile and bulbar strictures measuring over 2 cm, resulting from a straddle injury. Forty-three patients were selected who underwent urethroplasty in 2021 and completed a one-year follow-up in 2022. Uroflowmetry (UFM) and the International Index of Erectile Function (IIEF) assessment data were obtained from the patients' medical records. Success was defined as the patient attaining catheter freedom and achieving a maximum flow rate exceeding 15 ml/sec after one year.

Results: The mean UFM at one year was 20.89 ml/s. Four patients underwent endo-urological intervention (direct visual internal urethrotomy), and one patient needed a second double-face urethroplasty. After one year, the double-face BMG urethroplasty achieved an overall success rate of 88.4%.

Conclusion: Double-face BMG urethroplasty is a reliable and effective surgical technique for the treatment of near obliterative or obliterative long anterior urethral strictures.
