PURPOSE Significant concerns remain regarding the long-term outcomes of AMS 800 artificial urinary sphincter (AUS) implants in men. The objective was to assess the long-term AUS reintervention (replacement or removal) rates after a first-ever AUS implantation. MATERIALS AND METHODS This population-based retrospective cohort study included all men age ≥ 18 years in France who underwent a first-ever AUS implantation (identified using a unique device identifier) for male stress urinary incontinence (SUI) after prostate cancer (PCa) or benign prostatic hyperplasia (BPH) treatment, between January 1, 2006, and December 31, 2018. The primary outcome was reintervention-free survival rates (replacements and removals), estimated using the Kaplan-Meier method. Secondary outcomes were replacement and removal. A multivariable Cox proportional hazards model was used to assess associations between patient and hospital factors and the hazard of reintervention. RESULTS The study included 8475 men with a median age of 69 years (IQR, 65-74) and a median follow-up time of 6 years (IQR, 3-9). Reintervention-free survival was 71% (95% CI, 70-72) at 2 years, 57% (95% CI, 55-58) at 5 years, and 40% (95% CI, 38-41) at 10 years. Reintervention-free survival was lower after BPH surgery, after radiotherapy combined with RP, and in centers performing fewer implantations. Removal-free survival was 83% (95% CI, 83%-84%) at 2 years, 75% (95% CI, 74%-76%) at 5 years, and 66% (95% CI, 65%-68%) at 10 years. CONCLUSIONS Among men undergoing AUS implantation for SUI because of PCa or BPH treatment, the probability of reintervention was 29% within 2 years after implantation. The median time to reintervention was 6.6 years (IQR, 6.4-7.1), and the reintervention-free survival rate at 10 years was 40%. These insights can inform therapeutic decision making for patients and surgeons during the management of male SUI.

男性人工尿道括约肌植入物:一项基于国家医疗保健数据系统的研究,旨在评估法国的再干预。



目的 对男性 AMS 800 人工尿道括约肌 (AUS) 植入物的长期结果仍然存在重大担忧。目的是评估首次 AUS 植入后的长期 AUS 再干预(替代或移除)率。材料和方法 这项基于人群的回顾性队列研究包括 2006 年 1 月 1 日至 2018 年 12 月 31 日期间,法国所有 18 岁≥男性男性,他们在前列腺癌 (PCa) 或良性前列腺增生 (BPH) 治疗后接受了有史以来首次 AUS 植入(使用唯一设备标识符识别)男性压力性尿失禁 (SUI)。主要结局是无再干预生存率 (更换和移除),使用 Kaplan-Meier 方法估计。次要结局是替换和移除。使用多变量 Cox 比例风险模型评估患者和医院因素与再干预风险之间的关联。结果 该研究包括 8475 名男性,中位年龄为 69 岁 (IQR,65-74),中位随访时间为 6 年 (IQR,3-9)。2 年无再干预生存率为 71% (95% CI,70-72),5 年为 57% (95% CI,55-58),10 年为 40% (95% CI,38-41)。BPH 手术后、放疗联合 RP 后以及植入较少的中心无再干预生存率较低。2 年无脱落生存率为 83% (95% CI,83%-84%),5 年为 75% (95% CI,74%-76%),10 年为 66% (95% CI,65%-68%)。结论 在 PCa 或 BPH 治疗接受 AUS 植入 SUI 的男性中,植入后 2 年内再次干预的概率为 29%。再干预的中位时间为 6.6 年 (IQR,6.4-7.1),10 年无再干预生存率为 40%。 这些见解可以为患者和外科医生在男性 SUI 管理期间的治疗决策提供信息。
