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.
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.
Non-transecting urethroplasty to treat short urethral strictures associated with an artificial urinary sphincter may increase the success of artificial sphincter replacement.
人工尿道括约肌植入术是男性中重度压力性尿失禁的标准治疗方法。我们报告一例在接受尿道成形术及随后更换植入物的患者中,人工尿道括约肌相关尿道狭窄的病例。
一名64岁曾接受耻骨后根治性前列腺切除术的男性因压力性尿失禁前来我科就诊。植入了人工尿道括约肌,尿失禁症状得以缓解。11年后,患者因排尿症状再次前来。尿道镜检查和逆行尿道造影显示阴茎部尿道狭窄,长度约2毫米。患者接受了植入物取出及非横断性吻合尿道成形术。术后尿道镜检查证实狭窄已解除。6个月后进行了人工尿道括约肌再植入,恢复了控尿功能。
采用非横断性尿道成形术治疗与人工尿道括约肌相关的短尿道狭窄,可能会提高人工括约肌置换的成功率。
