Background:
According to the literature, restoration of pelvic organ prolapse also restores urinary continence. However, it is difficult to determine which exact surgical procedure actually led to urinary continence due to a lack of standardisation among these techniques. For example, an apical fixation is broadly defined in terms of type and shape of implanted material, anatomical fixation sides and tensioning. The aim of this study was to evaluate the effect of bilateral uterosacral ligament replacement with alloplastic tapes of defined lengths on symptoms of urinary incontinence.
Patients And Methods:
Patients with urinary incontinence and pelvic organ prolapse underwent an apical suspension. Thereby, both uterosacral ligaments (USL) were replaced by alloplastic structures of defined length. These alloplastic tapes had defined lengths in all patients of 9, 10, or 11 cm in length. They were sutured on both sides of the cervix, placed in the left and right peritoneal fold of the USL, and were sutured laterally to the prevertebral fascial layer of the sacral vertebra at the level of S2. Furthermore, all patients received additional transobturator tape. Pelvic organ prolapse was classified according to the Baden-Walker system, and urinary incontinence symptoms according to validated questionnaires.
Results:
Four months after bilateral USL replacement, apical suspension was restored in all 31 patients. In addition, urinary continence was re-established in 18 out of these 31 patients (58%). The highest continence rate was observed in patients in which both USL were replaced with alloplastic tapes of 9 cm in length.
Conclusion:
The findings indicated the importance of USL integrity for urinary continence. In particular, a defined length for both USL seems to be important for (re-)establishing urinary continence.
