Abstract
Introduction and hypothesis
The objective is to describe the anatomical position of tension-free vaginal tape Secur (TVT-S) in the U position regarding possible injury and fixation site.
Methods
We placed TVT-S inserters bilaterally in 13 embalmed and five fresh frozen female bodies. After dissection, we measured distances from the obturator bundle.
Results
In embalmed bodies, the mean distance of TVT-S from the obturator bundle was 2.83 cm (standard deviation (SD) 0.87 cm) on the left, 2.92 cm (SD 1.24 cm) on the right. Perforation of the fascia of obturator internus muscle occurred in 38.5%. In fresh frozen bodies, results were fundamentally similar (p > 0.05).
Conclusions
There is a risk of injury to the obturator bundle and urinary bladder during TVT-S; however, there is a significant risk of inserting the TVT-S inserter outside the obturator internus muscle (into the lesser pelvis). The position of TVT-S does not change significantly after legs mal-positioning.
