Sacrocolpopexy without concomitant posterior repair improves posterior compartment defects

Area of Science:

• Urogynecology
• Pelvic Floor Surgery
• Female Pelvic Medicine

Background:

• Pelvic organ prolapse (POP) significantly impacts women's quality of life.
• Sacrocolpopexy (SC) is a surgical option for POP, but its effect on posterior compartment topography requires further investigation.
• Understanding compartment-specific outcomes is crucial for surgical planning.

Purpose of the Study:

• To evaluate posterior vaginal compartment topography one year after sacrocolpopexy (SC) in women with symptomatic POP.
• To assess the objective cure rates and identify common sites of POP recurrence after SC.
• To determine if SC alone, without concomitant posterior repair, adequately restores posterior vaginal anatomy.

Main Methods:

• Prospective study including women undergoing SC for symptomatic POP without concurrent anterior or posterior repairs.
• Vaginal topography assessed using POP quantification (POPQ) at baseline and 1-year postoperatively.
• Analysis of compartment-specific prolapse stages (anterior, posterior, apical) at 1-year follow-up.

Main Results:

• Objective cure (Stage 0/I POP) was achieved in 75% of women (112/149) one year after SC.
• The anterior compartment showed the highest rate of POP persistence or recurrence (Ba ≥ stage II in 23 women).
• The posterior compartment (Bp ≥ stage II in 12 women) and apex (C ≥ stage II in 2 women) had lower recurrence rates.

Conclusions:

• Sacrocolpopexy alone effectively restores posterior vaginal topography in the majority of women.
• SC demonstrates high objective cure rates for POP one year post-surgery.
• Anterior compartment prolapse is the most frequent site of recurrence or persistence after SC.
