EVALUATION OF THE PELVIC FLOOR MUSCLES BEFORE AND AFTER SURGERY FOR ISOLATED URINARY INCONTINENCE AND ASSOCIATED PELVIC ORGAN PROLAPSE REPAIR
Urinary Incontinence, Pelvic Organ Prolapse, Pelvic Floor Musculature, Quality of Life, Vaginal Manometry
The objective of this study is to evaluate the quality of life and functionality of the pelvic floor muscles in women undergoing surgery for isolated urinary incontinence and associated bladder prolapse correction. A prospective cohort study was conducted with women who were indicated for surgery to correct isolated urinary incontinence (IUg group = 51) and associated pelvic organ prolapse (IU+POPg group = 49). All volunteers were assessed before surgery (T1) and followed up at 3 months (T3), 6 months (T4), and 12 months (T5) post-surgery. The assessment stages included the application of an evaluation form with sociodemographic data, functional examination of the pelvic floor muscles (vaginal manometry), and the application of the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB). An unpaired t-Student test was applied to compare sociodemographic and clinical data, and one-way repeated measures ANOVA was used to assess differences in the questionnaire and manometry scores at the four time points. Bonferroni post-test was applied when a statistical difference was identified. A significance level of 5% was adopted for all analyses. The results showed a similar improvement in urinary symptoms in both groups. Women who underwent only urinary incontinence correction showed better pelvic floor muscle (PFM) function over one year post-surgery. It is concluded that after surgery, there is a decrease in PFM function, with those undergoing prolapse and urinary incontinence correction showing worse function. Given these findings, pelvic floor muscle training is suggested in the immediate postoperative period.
