Magnetic resonance imaging (MRI) was used to investigate whether tension-free vaginal tape (TVT) insertion (according to Ulmsten) leads to morphologic changes of the stress continence control system.
Twenty women (mean age 53.4 years) with clinically and urodynamically proven stress urinary incontinence without prolapse were examined by MRI before and 13 months after TVT insertion.
Postoperative MRI showed a signal intensity loss of the suburethral portion of the endopelvic fascia in the area of the anterior vaginal wall in 9/20 women with additional signal loss of the paraurethral portion of the fascia in 3/20 women. No morphologic changes of the levator ani muscle and the urethra were seen postoperatively.
TVT insertion does not damage the structures of the stress continence control system or impact on their topographic relationships. MRI identified no excessive scar formation resulting from integration of the TVT.
采用磁共振成像（MRI）研究无张力阴道吊带术（TVT，根据乌尔姆斯特伦术式）的植入是否会导致压力性尿失禁控制系统的形态学改变。
对20名临床及尿动力学检查证实为压力性尿失禁且无脏器脱垂的女性（平均年龄53.4岁）在TVT植入术前及术后13个月进行MRI检查。
术后MRI显示，20名女性中有9名阴道前壁区域盆腔内筋膜尿道下部分信号强度丧失，其中3名女性尿道旁部分筋膜信号额外丧失。术后未观察到肛提肌和尿道的形态学改变。
TVT植入不会损害压力性尿失禁控制系统的结构，也不会影响其局部解剖关系。MRI未发现TVT植入后形成过多瘢痕。
