BACKGROUND: Transient postoperative urinary incontinence is a bothersome complication of holmium laser enucleation of the prostate (HoLEP). The effects of preoperative pelvic floor muscle exercise (PFME) for early recovery of continence after HoLEP have never been elucidated. The aim of this study was to determine the benefit of preoperatively started PFME for early recovery of continence after HoLEP. METHODS: We randomly assigned patients to start PFME preoperatively and continue postoperatively (group A) or start PFME no earlier than the postoperative period (group B). The primary outcome was time to complete urinary control, defined as no pad usage. The secondary outcome was measured using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score. Univariate and multivariate analyses were performed to identify parameters associated with recovery of continence after HoLEP. RESULTS: Seventy patients were randomized across groups A (n = 35) and B (n = 35). Patients' characteristics were not different between groups A and B. The postoperative urinary incontinence rate significantly decreased in group A compared with that in group B at 3 months postoperatively (3% versus 26% (p = 0.01)). However, there were no significant differences between groups A and B at 3 days (40% versus 54% (p = 0.34)), 1 month (37% versus 51% (p = 0.34)), and 6 months (0% versus 3% (p = 1.00)) postoperatively, respectively. The postoperative ICIQ-SF score was not significantly different between groups A and B at any time point postoperatively. In univariate analysis, patients who performed preoperative PFME had a 0.56-fold lower risk of urinary incontinence 1 month after HoLEP and a 0.08-fold lower risk of urinary incontinence 3 months after HoLEP. CONCLUSIONS: Preoperatively started PFME appears to facilitate improvement of early urinary continence after HoLEP. TRIAL REGISTRATION: The study was registered with the University Hospital Medical Information Network Clinical Trials Registry in Japan (UMIN000034713); registration date 31 October 2018. Retrospectively registered.
