Background: Because of its low recurrence rate and safety, laparoscopic sacrocolpopexy (LSC) is an increasingly popular treatment for pelvic organ prolapse (POP). Although LSC may improve voiding function, it can also lead to de novo stress urinary incontinence. The exact effects of LSC on voiding function, and the mechanisms responsible, remain unclear. Therefore, in this study we prospectively evaluated the impact of LSC on voiding function by performing a pre- and postoperative urodynamic study of patients with stage 3 or worse POP. Methods: Urinary status was evaluated before and 3 months after LSC. Pre- and postoperative evaluations included medical history, clinical examination, urodynamic studies, chain cystography, and residual urine volume measurement. Urinary symptoms were assessed using the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS). Results: The nonrecurrence rate at 3 months was 82.3%. All recurrences involved bladder prolapse. In addition to the absence of a significant change in OABSS, the improvement in IPSS suggests that subjective voiding symptoms improved. Although the maximum urinary flow rate did not significantly change, bladder volume at first sensation increased, urinary storage function improved, and residual urine volume decreased. There were no perioperative complications, and no patient reported postoperative difficulty in urination or urinary retention. The retrovesical angle significantly decreased. Conclusions: The modified LSC in women with POP provides good functional outcomes in terms of IPSS, post-void residual volume (PVR), and urinary storage function.
