The objective of the study is to clarify potential risks to the dorsal nerve of the clitoris (DNC) and obturator canal using different minimally invasive slings.
Ten embalmed hemipelves were dissected to demonstrate the course of the DNC and the obturator canal. On each cadaver, tension-free vaginal tape (TVT), transobturator in-out (TVT-O) and transobturator out-in (Monarc) procedures were performed. Distances between the DNC and the obturator canal to the different devices were measured.
The DNC passes beneath the pubic bone at a distance of 14.3 +/- 4.7 mm of the midline. The distances of the different devices to the DNC were similar. The distance to the obturator canal was significantly different, with TVT being the furthest (40.1 +/- 3.7 mm) and TVT-O the closest (19.3 +/- 3.1 mm; p < 0.0001).
Given the course of the DNC along the medial aspect of the ischiopubic ramus, the out-in technique may be safer. The in-out technique is the closest to the obturator canal.
本研究的目的是阐明使用不同的微创吊带对阴蒂背神经（DNC）和闭孔管的潜在风险。
解剖10个防腐处理的半骨盆以展示DNC和闭孔管的走行。在每个尸体上进行无张力阴道吊带术（TVT）、经闭孔内外穿刺术（TVT-O）和经闭孔外内穿刺术（Monarc）。测量DNC和闭孔管与不同器械之间的距离。
DNC在耻骨下方距中线14.3±4.7mm处通过。不同器械与DNC的距离相似。与闭孔管的距离有显著差异，TVT最远（40.1±3.7mm），TVT-O最近（19.3±3.1mm；p<0.0001）。
鉴于DNC沿耻骨坐骨支内侧走行，外内穿刺技术可能更安全。内外穿刺技术最靠近闭孔管。
