Effect of detrusor underactivity on surgical outcomes of holmium laser enucleation of the prostate.

OBJECTIVE: To evaluate the effect of detrusor underactivity (DUA) on the postoperative outcomes of holmium laser enucleation of the prostate (HoLEP) in patients with benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: Patients with BPH who underwent HoLEP between January 2018 and December 2022 were enrolled in this prospective database study. Patients were divided into DUA (bladder contractility index [BCI] <100) and non-DUA (BCI ≥100) groups. Objective (maximum urinary flow rate [Qmax], post-void residual urine volume [PVR]) and subjective outcomes (International Prostate Symptom Score [IPSS], Overactive Bladder Symptom Score [OABSS], satisfaction with treatment question [STQ], overall response assessment [ORA], and willingness to undergo surgery question [WUSQ]) were compared between the two groups before surgery, and at 3 and 6 months after HoLEP. RESULTS: A total of 689 patients, with a mean (standard deviation [SD]) age of 69.8 (7.1) years, were enrolled. The mean (SD) BCI in the non-DUA (325 [47.2%]) and DUA (364 [52.8%]) groups was 123.4 (21.4) and 78.6 (14.2), respectively. Both objective (Qmax and PVR) and subjective (IPSS, IPSS-quality of life, and OABSS) outcomes after surgery significantly improved in both groups. The Qmax was lower in the DUA than in the non-DUA group postoperatively. At 6 months postoperatively, the total IPSS was higher in the DUA than in the non-DUA group. There were no significant differences in surgical complications between the two groups. Responses to the STQ, ORA, and WUSQ at 6 months postoperatively demonstrated that the patients were satisfied with the surgery (90.5% in the DUA group; 95.2% in the non-DUA group), their symptoms improved with surgery (95.9% in the DUA group; 100.0% in the non-DUA group), and they were willing to undergo surgery again (95.9% in the DUA group; 97.9% in the non-DUA group). There were no significant differences in the responses to the STQ and WUSQ between the two groups. CONCLUSION: Our midterm results demonstrated that patients with BPH and DUA showed minimal differences in clinical outcomes after HoLEP compared to those without DUA. The overall satisfaction was high in the DUA group.

Factors Considered by Experienced Urologists when Selecting Alpha-Blockers for Patients with Lower Urinary Tract Symptoms or Benign Prostatic Hyperplasia according to Age.

INTRODUCTION: The objectives of the study were to examine the opinions of urology specialists on whether there are actual differences in efficacy among α1-blockers and to identify the factors that should be considered when prescribing these medications according to age. METHODS: We surveyed 50 South Korean urology specialists with over 3 years of clinical experience in secondary or tertiary hospitals in July-August 2021. The survey covered urologists' demographics, awareness of α1-blocker prescription differences, and key factors in α1-blocker selection based on LUTS severity and patient age. RESULTS: Overall, 82% of the respondents believed that there were differences in the efficacy of α1-blockers in actual practice according to age. Over 90% of the respondents agreed on the need for head-to-head comparison studies to compare the effects of different α1-blockers. Regardless of the severity of LUTS, urologists prioritize cardiovascular side effects when prescribing α1-blockers to patients aged ≥70 years. Further, 19% of the urologists prioritized ejaculatory side effects for mild-to-moderate LUTS and 9% for severe LUTS (p < 0.001). CONCLUSIONS: This study shows that head-to-head studies comparing the efficacy of different α1-blockers are highly valuable for the real-world clinical application of α1-blockers. Notably, urologists prioritize cardiovascular and ejaculatory side effects in older and younger patients while prescribing α1-blockers, respectively.

Clinical outcomes of holmium laser enucleation of the prostate: A large prospective registry-based patient cohort study under regular follow-up protocol.

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.
