The magnetic sphincter consists of a bow shaped retropubical implanted magnet, fixed on the inner rim of the symphysis. Another removable magnet is installed in the vagina, both gently closing the urethra. 31 patients with severe recurrent stress incontinence after repeated operations (hypotone urethra mean = 17 cm H2O upp rest, mean = 59 years) were operated on with the magnetic sphincter system. 16 patients have been operated with this method, getting a curing rate of 12.4 continent patients do not use to vaginal magnet because of complaints. This system has now been modified. The modification described herein consists of a colposuspension over the upper edge of the implanted magnet. With this modification, 12 of the patients became continent, 10 resulting from the colposuspension alone, 2 became adequately continent with the additional intravaginal magnet. The idea of a colposuspension over the upper edge of the magnetic implant is convincing by its success in recurrent stress incontinence, and gives the possibility to increase the continence rate by using the intravaginal magnet. The operation is easy to perform and the result effective.
磁性括约肌由一个呈弓形的耻骨后植入磁体组成，该磁体固定在耻骨联合的内缘。另一个可移除的磁体安装在阴道内，二者共同轻柔地闭合尿道。对31例反复手术治疗后仍患有严重复发性压力性尿失禁的患者（尿道低张力平均为17cmH₂O，静息时平均为59岁）采用磁性括约肌系统进行手术。16例患者接受了该方法手术，治愈12例，4例因出现不适而未使用阴道磁体。该系统现已改进。本文所述的改进包括在植入磁体的上缘进行阴道悬吊术。通过这种改进，12例患者实现了控尿，其中10例仅通过阴道悬吊术实现，2例通过额外使用阴道内磁体达到了充分控尿。在复发性压力性尿失禁治疗中，在磁性植入物上缘进行阴道悬吊术的想法因取得成功而令人信服，并且通过使用阴道内磁体提高了控尿率。该手术操作简便，效果显著。
