Urethral Stricture Associated With an Artificial Urethral Sphincter: A Case Report

This is the authors' abstract. We don't add key points for this paper.

Introduction: Artificial urinary sphincter implantation is the standard treatment for moderate-to-severe stress urinary incontinence in men. We report a case of urethral stricture associated with an artificial urinary sphincter in a patient who underwent urethroplasty and subsequent replacement of the implant. Case Presentation: A 64-year-old man who had undergone radical retropubic prostatectomy presented to our department for stress urinary incontinence. An artificial urinary sphincter was implanted, and the incontinence resolved. Eleven years later, the patient returned because of voiding symptoms. Urethroscopy and retrograde urethrography revealed a pendulous urethral stricture, measuring approximately 2 mm in length. The patient underwent implant removal and non-transecting anastomotic urethroplasty. Postoperative urethroscopy confirmed resolution of the stricture. Artificial urinary sphincter reimplantation was performed 6 months later, restoring continence. Conclusion: Non-transecting urethroplasty to treat short urethral strictures associated with an artificial urinary sphincter may increase the success of artificial sphincter replacement.
