Artificial urinary sphincter cuff erosion has become rare but remains a dreaded consequence of sphincter implantation. Our experience indicates that with rational and systematic management of this problem, sphincter reimplantation can restore continence in many of these patients. During a ten-year period, 412 artificial sphincters were implanted at the Mayo Clinic. Bladder neck or urethral erosion occurred in 64 patients (15.5%). Ultimately, 38 patients had reimplantation, and the outcome was successful in 32 (84%). After the advent of delayed activation, the incidence of cuff erosion decreased greatly--from a peak of 18 percent (12 of 66 cases) in 1977 to 1.3 percent (1 of 79 cases) in 1985.
人工尿道括约肌袖套糜烂已较为罕见，但仍是括约肌植入术令人担忧的后果。我们的经验表明，通过合理、系统地处理这一问题，括约肌再植入术可使许多此类患者恢复控尿能力。在十年期间，梅奥诊所共植入了412个人工括约肌。64例患者（15.5%）发生膀胱颈或尿道糜烂。最终，38例患者接受了再植入术，32例（84%）获得成功。延迟激活技术出现后，袖套糜烂的发生率大幅下降——从1977年的峰值18%（66例中的12例）降至1985年的1.3%（79例中的1例）。
