To investigate the relationship between the anatomical position of the anterior arm of the mesh, measured by ultrasound through the bladder neck-mesh distance technique and the surgical outcomes after laparoscopic sacrocolpopexy (SCP) for apical prolapse. It was a retrospective analysis of prospectively collected data in a tertiary care hospital. Between January 2019 and September 2019, 63 women who underwent laparoscopic SCP due to apical prolapse were included. Bladder neck-mesh distance was measured immediately after surgery. The pelvic floor was evaluated using the Pelvic Organ Prolapse Quantification (POP-Q) System before, 1month, and 2.7years (mid-term) after the surgery. Post-operative stress urinary incontinence (SUI) and Patient Global Impression of Improvement (PGI-I) scores were also assessed. The correlation between bladder neck-mesh distance and the post-operative outcomes was investigated using the Spearman rank correlation coefficient. At mid-term follow-up visit, bladder neck-mesh distance was inversely correlated with the correction of apical prolapse and post-operative SUI. No correlation was detected with the anterior compartment prolapse correction. PGI-I scores were high in all patients at mid-term follow-up, irrespective of bladder neck-mesh distance values. The shorter the bladder neck-mesh distance, the better the outcome for apical compartment repair. Bladder neck-mesh distance had no correlation with the anterior anatomical correction. Shorter bladder neck-mesh distance values were positively correlated to better PGI-I scores and a higher risk of SUI.
