The new magnetic closure device consists of a retropubically implanted magnet and another removable intravaginal magnet, which gently closes the urethra. The system has shown its proper function in animal experiments up to an urethral pressure of 120 cm water pressure and in an animal model - female merino sheep - during a period of observation up to 33 weeks. The first experiences with a magnetic urethral closure system in female patients with recurrent urinary incontinence, when common incontinence surgery is useless (no descensus, extremely hypotone urethral), are promising. Continence can be achieved, the handling is easy and can be managed by intelligent and well motivated patients. The system has been used successfully in 7 patients carrying the magnet in the vagina over 8 h daily for up to 3 years.
这种新型磁闭合装置由一个经耻骨后植入的磁体和另一个可移除的阴道内磁体组成，该装置可轻柔地闭合尿道。在动物实验中，该系统在尿道压力达到120厘米水柱时显示出其正常功能，并且在一个动物模型——雌性美利奴绵羊中，在长达33周的观察期内也表现良好。对于常规失禁手术无效（无脏器脱垂、尿道极度低张力）的复发性尿失禁女性患者，首次使用磁尿道闭合系统的经验很有前景。可以实现控尿，操作简便，并且有智慧且积极性高的患者能够自行操作。该系统已成功应用于7名患者，她们每天在阴道内佩戴磁体超过8小时，最长达3年。
