Introduction & Objectives: Urinary incontinence (UI) is the second most common side effect after radical prostatectomy (RP). EAU Guidelines do not recommend pre- and post-operative pelvic floor muscles (PFM) training for prevention of long term UI. The objective of our study was to evaluate the impact of preoperative PFM strength (PFMS) and endurance (PFME) on UI after RP. Materials & Methods: For men who underwent RP, PFMS and PFME were measured before surgery using a perineometer. UI was tested using 8-hours pad test on the day of catheter removal, and at 1, 3 and 6 months after RP. Men were described continent when urine loss was from 0 to 5gr per test. According to the baseline PFMS and PFME values all men were divided into 3 groups: weak (<80) vs. moderate (81-99) vs. strong PFMS (>100mmH2O) and weak (<6) vs. moderate (7-9) vs. strong (>10s.) PFME. The correlation between baseline PFMS or PFME and postoperative UI was assessed using Spearman correlation coefficient. UI values comparison among groups was made using ANOVA test. Multivariate logistic regression analysis was used for the detection predictors for continence. Results: In total, 148 men were included into the study. The median (quartiles) baseline PFMS and PFME were 94.0 (82-101) mmH2O and 8 (6-10) s, respectively. UI on the 1st day after catheter removal and at 6 months after RP were 285 (234-359) and 20 (0-35) mL, respectively. A moderate reverse correlation was detected between PFMS and UI on the 1st day and at 6 months – r=-0.63 and r=-0.7 (p<0.0001), respectively. A moderate correlation was found also between baseline PFME and UI on the 1st day and at 6 months – r=-0.6 and r=-0.55 (p<0.0001). Age, body mass index and cancer characteristics were not different between groups created by baseline PFMS and PFME. On the 1st day and at 6 months UI was different among weak (n=37) vs. moderate (n=62) and strong (n=28) groups according to the bas[...].
