Abstract
INTRODUCTION AND HYPOTHESIS: Pelvic floor muscle training (PFMT) improves urinary incontinence and mild pelvic organ prolapse (POP). We aimed to investigate the effect of preoperative PFMT on urinary and colorectal-anal distress and related quality of life (QoL) in women with severe POP scheduled for surgery. METHODS: Randomized controlled trial of 159 women scheduled for POP surgery (intervention = 81, controls = 78). Intervention consisted of daily PFMT from inclusion to the day of surgery. Symptoms and QoL were assessed at inclusion, day of surgery and 6 months postoperatively using the Urinary Distress Inventory (UDI-6), Colorectal-Anal Distress Inventory (CRADI-8), Urinary Impact Questionnaire (UIQ) and Colorectal-Anal Impact Questionnaire (CRAIQ) (range 0-100). Mixed model statistical analyses were used. RESULTS: One hundred fifty-one (95%) women completed the study (intervention = 75, controls = 76). Mean waiting times until surgery and follow-up were 22 and 28 weeks. There was no difference in mean postoperative symptom and QoL scores (95% CI) between the intervention and control group: UDI-6 16 (12-21) vs. 17 (13-22), CRADI-8 15 (11-18) vs. 13 (10-16), UIQ 11 (7-15) vs. 10 (6-13) and CRAIQ 5 (2-7) vs. 6 (4-9), all p > 0.05. Overall mean scores were reduced from baseline to postoperative follow-up: UDI-6 37 (33-41) vs. 17 (14-20), CRADI-8 22 (19-25) vs. 14 (11-16); UIQ 28 (24-32) vs. 10 (7-13) and CRAIQ 16 (12-19) vs. 5 (3-7), all p < 0.01. CONCLUSIONS: We found no added effect of preoperative PFMT on symptoms or QoL related to urinary and colorectal-anal distress in women scheduled for POP surgery. They achieved symptomatic improvement postoperatively regardless of PFMT. CLINICAL TRIAL REGISTRATION: The study was registered in clinicaltrials.gov: NCT 03,064,750.
