RESUMO
OBJECTIVES: To evaluate the pubocervical fascia (PF) in patients with pelvic organ prolapse (POP) using 3-dimensonal endovaginal ultrasonography (EVUS) and to correlate the PF appearance with both pelvic examination and intraoperative findings during ultrasonographic robotic-assisted laparoscopic sacrocervicopexy and pubocervical fascia reconstruction (u-RALS-PFR). METHODS: A retrospective analysis was performed in 120 women with symptomatic POP. Preoperative evaluation was done using EVUS. We identified areas of PF weakness based on pelvic examination as hypoechoic and hyperechoic defects (HHD) between the bladder and vagina. Study measurements included distance from the HHD to the pubic symphysis, HHD to the bladder neck, HHD to the posterior bladder wall, and hypoechoic-hyperechoic area. We correlated these metrics with the respective POP-Q stages and findings during u-RALS-PFR. RESULTS: Using the quantitative measures during EVUS, we found a significant association between mean HHD (2.7 cm) and POP-Q stage III, and between HHD and number of plications performed during surgery. The larger the HHD, the more severe the POP-Q stage of the anterior compartment of the vaginal wall; thus, more plications were performed on the PF (7-12 plications) during robotic sacrocervicopexy, and consequently the anterior arm of the Y-mesh was significantly trimmed (6-8 cm). CONCLUSION: HHD obtained by EVUS was associated with severe POP-Q stage III and seemed to correlate with the number of plications during robotic sacrocervicopexy. Performing these plications on the PF significantly decreased the length of the anterior vaginal mesh needed for the procedure. These findings may open new applications for preoperative ultrasonography in evaluation and treatment of patients with apical and anterior POP.
