Abstract:
Purpose:This study investigated urinary incontinence (UI) following holmium laser enucleation of the prostate (HoLEP), based on the postoperative period, type of UI, and severity according to prostate volume.
Methods:We analyzed prospectively collected data from patients who underwent HoLEP for benign prostatic hyperplasia at Seoul National University Hospital between January 2010 and June 2022. Patients were followed-up at 2 weeks, 3 months, and 6 months postoperatively. The patients were divided into 3 prostate volume groups: A (30–80 mL), B (81–120 mL), and C (>120 mL). We compared clinical outcomes and UI rates between the groups.
Results:In total, 1,675 patients were included. The preoperative urgency UI (UUI) rate was 16.1%, with no significant difference between the groups (P=0.81). Two weeks postoperatively, the UUI rate was 6.0% (including a de novo UUI rate of 4.2%), with no significant differences between the groups. The stress UI (SUI) rate at 2 weeks postoperatively was 6.3%, and increased with larger prostate volume (P=0.04). The UUI and SUI rates decreased to 0.9% and 1.2%, respectively, 6 months postoperatively. Six months postoperatively, the SUI rate was significantly lower in group A (P=0.02), whereas the UUI rate did not differ between the groups (P=0.69).
Conclusions:Our results demonstrated that the preoperative UUI rate was high at baseline. Both the UUI and SUI rates continuously decreased up to 6 months postoperatively. Although the SUI rates significantly differed according to prostate volume, there was no significant difference in the UUI rate.
