The aim of this study was to assess the length of adjustable single-incision midurethral tape (SIMS; Ajust), which is needed to fix this tape to the obturator membrane. From these data, we can deduce the optimal length of the SIMS.
For this study, we employed the intra-operative data of patients included in a single-center randomized trial comparing the efficacy of Tension free vaginal tape obturator (TVT-O) and Ajust. The length of the Ajust tape was calculated using the formula: total length of the tape minus the length of the stylet used for the tape lock, minus the length of the lock minus the width of the two anchors. The length of the obturator tape was calculated using the formula: total tape length minus the snipped parts of the tape. The correlation coefficient of the tape length to basic biometric parameters, such as height, weight, and body mass index, was calculated.
For this study, data from 50 women from each group, TVT-O and Ajust, were used. The mean length of the Ajust tape inside the body is 11.6 cm (SD 0.9), with a minimum length of 9.6 cm and a maximum length of 14.6 cm. The mean length of TVT-O tape inside the body is 20.3 cm (SD 2.1), with a minimum of 14.8 cm and a maximum length of 24.5 cm.
This study demonstrates that to achieve continence it is necessary to use different lengths of single-incision tape. Inappropriate SIMS length could cause failure related to the tape itself and not to the TVT technique.
本研究旨在评估可调节单切口尿道中段吊带（SIMS；Ajust）固定于闭孔膜所需的长度。根据这些数据，我们可以推断出SIMS的最佳长度。
在本研究中，我们采用了一项单中心随机试验中患者的术中数据，该试验比较了无张力阴道吊带闭孔（TVT-O）和Ajust的疗效。Ajust吊带的长度使用以下公式计算：吊带总长度减去用于吊带锁定的探针长度，减去锁定部分的长度，再减去两个锚定器的宽度。闭孔吊带的长度使用以下公式计算：吊带总长度减去吊带被剪断部分的长度。计算吊带长度与身高、体重和体重指数等基本生物特征参数的相关系数。
本研究使用了TVT-O组和Ajust组各50名女性的数据。体内Ajust吊带的平均长度为11.6厘米（标准差0.9），最短长度为9.6厘米，最长长度为14.6厘米。体内TVT-O吊带的平均长度为20.3厘米（标准差2.1），最短为14.8厘米，最长长度为24.5厘米。
本研究表明，为实现控尿，有必要使用不同长度的单切口吊带。不合适的SIMS长度可能导致与吊带本身相关的失败，而非TVT技术相关的失败。
