Objectives
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.
Study design
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.
Results
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).
Conclusion
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.
