The objective of the study was to evaluate the anatomic relationships of anchor points of single-incision midurethral slings with 2 common placement trajectories.
In 30 female pelvic halves, a probe was introduced through a suburethral tunnel following 45° and 90° angle trajectories. The corresponding anchor points were tagged. Distances to the obturator canal, accessory obturator vessels, dorsal vein of clitoris, and external iliac vein were recorded.
Both suburethral tunnel trajectories and their respective anchor points remained caudad to the obturator internus muscle in 100% of dissections. The closest distance between either anchor point to the obturator canal was 1.6 cm. The closest distance from the 45° and 90° anchor points to the accessory obturator vessels was 1.6 and 1.5 cm, respectively.
The anchor points of single-incision midurethral slings are in close proximity to vascular structures that could be injured with inadvertent entry into the retropubic space.
本研究旨在评估单切口尿道中段吊带的锚定点与两种常见置入轨迹的解剖关系。
在 30 个女性骨盆半体中，探针通过尿道下隧道以 45°和 90°角度轨迹引入。标记相应的锚定点。记录至闭孔管、副闭孔血管、阴蒂背静脉和髂外静脉的距离。
在所有解剖中，两条尿道下隧道轨迹及其各自的锚定点均位于闭孔内肌的尾侧。任一枚锚定点至闭孔管的最近距离为 1.6 厘米。45°和 90°锚定点至副闭孔血管的最近距离分别为 1.6 厘米和 1.5 厘米。
单切口尿道中段吊带的锚定点紧邻可能因意外进入耻骨后空间而受伤的血管结构。
