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.

Purpose: To evaluate the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) in a large prospective cohort of patients with benign prostatic hyperplasia (BPH) through systematic follow-up at a single institution. Materials and Methods: Clinical outcomes were analyzed between August 2008 and June 2022. Patients were followed-up at 2 weeks, 3 months and 6 months postoperatively. Results: A total of 3,000 patients (mean age, 69.6±7.7 years) underwent HoLEP. Baseline total International Prostate Symptom Score (IPSS) was 19.3±7.7 and maximum flow rate (Qmax) was 9.4±4.8 mL/s. Mean total prostate volume was 67.7±3.4 mL. Total operation time was 60.7±31.5 minutes, and catheterization time was 1.0 days (range, 1.0–1.0 days). At 6 months postoperatively, the total IPSS decreased to 6.6±5.8 and Qmax increased to 22.2±11.3 mL/s. Complications at 6 months postoperatively included stress urinary incontinence (SUI) in 36 patients (1.9%), urgency urinary incontinence (UUI) in 25 (1.3%), bladder neck contracture (BNC) requiring transurethral incision (TUI) in 16 (0.5%), and urethral stricture in 29 (1.0%). Eleven patients (0.4%) with prostatic fossa stones required stone removal. Sixty-one patients (2.0%) required secondary surgery (transurethral coagulation, 16 [0.5%];TUI for BNC, 16 [0.5%]; stone removal for prostatic fossa stones, 11 [0.4%]; and endoscopic internal urethrotomy for urethral stricture, 18 [0.6%]). Conclusions Mid-term follow-up results after HoLEP in BPH patients showed excellent efficacy and low complication rates. Unlike previous reports, the incidence of SUI and UUI after HoLEP was low, but the occurrence of de novo stone formation in prostatic fossa was notable.
