In this study, we present safety and efficacy data for a surgical alternative for the treatment of postprostate surgery urinary incontinence, based on the use of the periurethral constrictor, a two-part device--constrictor cuff and self-sealing valve with a tube--activated by injection of saline solution.
From May 2001 to October 2007, 30 patients with postprostate surgery urinary incontinence were submitted to implantation of the periurethral constrictor.
The mean follow-up was 42.1 months (range, 13-72). Twenty-two (73.3%) of the patients had functional devices and were socially continent. Among them, 20 patients voided spontaneously, whereas two performed intermittent catheterization. Revisions to exchange leaking valves were necessary in 4 cases, and since then these patients have been socially continent. In this series, with the exception of 4 cases of erosion, 3 cases of infection that required complete removal of the devices, and 1 case of detrusor hyper-reflexia, there were no other major complications.
The results of this retrospective study suggest that the implantation of the periurethral constrictor appears to be safe and effective as an alternative to the treatment of postprostate surgery urinary incontinence.
本研究旨在介绍一种基于尿道周围紧缩器（一种由紧缩袖套和带有导管的自封阀组成的两部分装置）的治疗前列腺手术后尿失禁的手术替代方案的安全性和疗效数据，该紧缩器通过注射生理盐水来激活。
2001 年 5 月至 2007 年 10 月，30 例前列腺手术后尿失禁患者接受了尿道周围紧缩器植入术。
平均随访时间为 42.1 个月（范围为 13-72 个月）。22 例（73.3%）患者的装置功能正常且具有社交自理能力。其中，20 例患者可自主排尿，2 例患者间歇性导尿。4 例患者因漏阀需要更换，此后这些患者具有社交自理能力。在本系列中，除 4 例侵蚀、3 例感染（需要完全取出装置）和 1 例逼尿肌反射亢进外，无其他严重并发症。
这项回顾性研究的结果表明，尿道周围紧缩器的植入作为治疗前列腺手术后尿失禁的一种替代方法似乎是安全有效的。
