Abstract
Introduction and hypothesis
The high prevalence of pelvic organ prolapse (POP) in women requires attention and constant review of treatment options. Sacrospinous ligament fixation (SSLF) for apical prolapse has benefits, high efficacy, and low cost. Our objective is to compare anterior and posterior vaginal approach in SSLF in relation to anatomical structures and to correlate them with body mass index (BMI).
Methods
Sacrospinous ligament fixation was performed in fresh female cadavers via anterior and posterior vaginal approaches, using the CAPIO®SLIM device (Boston Scientific, Natick, MA, USA). The distances from the point of fixation to the pudendal artery, pudendal nerve, and inferior gluteal artery were measured.
Results
We evaluated 11 cadavers with a mean age of 70.1 ± 9.9 years and mean BMI 22.4 ± 4.6 kg/m2. The mean distance from the posterior SSLF to the ischial spine, pudendal artery, pudendal nerve, and inferior gluteal artery were 21.18 ± 2.22 mm, 17.9 ± 7.3 mm, 19.2 ± 6.8 mm, and 18.9 ± 6.9 mm respectively. The same measurements relative to the anterior SSLF were 19.7 ± 2.7 mm, 18.6 ± 6.7 mm, 19.2 ± 6.9 mm, and 18.3 ± 6.7 mm. Statistical analysis showed no difference between the distances in the two approaches. The distances from the fixation point to the pudendal artery and nerve were directly proportional to the BMI.
Conclusions
There was no difference in the measurements obtained in the anterior and posterior vaginal approaches. A direct correlation between BMI and the distances to the pudendal artery and pudendal nerve was found.
