Hip osteoarthritis (OA) compromises functioning. Total hip replacement (THR) is the indicated treatment and may improve urinary incontinence (UI) and symptoms of overactive bladder (OAB).
Assess UI, OAB symptoms, and quality of life (QoL) impact in preoperative and postoperative periods of women submitted to THR and investigate associated factors.
A prospective cohort was conducted with 183 women submitted to THR. The International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), International Consultation on Incontinence Questionnaire-Overactive Bladder (ICIQ-OAB) and SF-12 questionnaires were administered pre- and 3 and 6 months after surgery.
Significant improvements were found in UI and QoL 3- and 6-month postoperatively in the overall sample and in the subgroup with preoperative UI. The multivariate regression revealed that the preoperative ICIQ-SF and ICIQ-OAB final scores were the best predictors of UI 6-month postoperatively. The factors the best predicted the occurrence of UI 6-month following THR were the preoperative ICIQ-OAB scores and preoperative UI. Each unit of increase in the ICIQ-OAB increases the chances of UI by 26.9% and preoperative UI increases the chances of postoperative UI by 18.7-fold. A weak but significant negative correlation was found between the ICIQ-SF score and the SF-12 score.
Significant improvements in UI, OAB and QoL were found at 3- and 6-month postoperatively. Preoperative ICIQ-SF and ICIQ-OAB final scores were the best predictors of UI at 6 months after surgery. We found significant association between urinary symptoms and THR, but this association is partially explained by current literature.
