To report on a safe endoscopic management technique for the treatment of an anastomotic stricture (AS) in patients with an artificial urinary sphincter (AUS).
Five patients with a history of salvage prostatectomy after radiation therapy that developed an AS after AUS placement were treated with a rigid ureteroscope and a Holmium YAG (Ho: YAG) laser to incise the AS. The AUS was opened and deactivated but not decoupled or removed during the procedure. The rigid ureteroscope allowed complete control of the laser fiber to incise the stricture at the 3 and 9 o' clock positions and then circumferentially.
There were no intraoperative complications and the mean operative time was 42.6 minutes. Of the 5 patients who underwent holmium laser incision of an AS after AUS placement, none developed AUS malfunction or required device replacement. No patients reported worsening of urinary incontinence after treatment. Two patients required repeat holmium laser incision for AS recurrence.
Using a rigid ureteroscope and a holmium laser to incise an AS after AUS placement seems to be a safe management option that does not damage the AUS or result in worsening incontinence. This treatment strategy provides an endoscopic alternative to using open surgical technique to uncouple or remove the AUS while treating the AS.
报告一种安全的内镜处理技术,用于治疗人工尿道括约肌(AUS)后吻合口狭窄(AS)。
5 例因放疗后挽救性前列腺切除术而导致 AUS 放置后发生 AS 的患者,采用硬性输尿管镜和钬激光(Ho:YAG)激光切开 AS。在手术过程中,AUS 被打开并停用,但未分离或移除。硬性输尿管镜可完全控制激光纤维,在 3 点和 9 点位置切开狭窄处,然后进行环状切开。
无术中并发症,平均手术时间为 42.6 分钟。在 5 例接受 AUS 放置后钬激光切开 AS 的患者中,无 1 例出现 AUS 故障或需要更换装置。治疗后无患者报告尿失禁加重。2 例患者因 AS 复发需要再次行钬激光切开。
使用硬性输尿管镜和钬激光切开 AUS 放置后的 AS 似乎是一种安全的管理选择,不会损坏 AUS 或导致尿失禁加重。这种治疗策略为治疗 AS 提供了一种内镜替代方案,避免了使用开放手术技术分离或移除 AUS。
