BMI = body mass index; POP = pelvic organ prolapse; pre-PUFR = preoperative peak urinary flow rate; pre-PVR = preoperative post-void residual; MCC = maximal cystometric capacity; VLPP = Valsalva leak point pressure; MUCP = maximal urethral closing pressure; PdetQmax = detrusor pressure at peak urinary flow; DO = detrusor overactivity; post-PUFR = peak urinary flow rate at one month after the Remeex procedure; post-PVR = post-void residual at one month after the Remeex procedure. p<0.05 was considered as statistically significant. Kruskal-Wallis test. Chi-square test.
