Objectives To compare postoperative complication rates of patients with metabolic syndrome (MetS) with patients without MetS after holmium laser enucleation of the prostate (HoLEP) for management of benign prostatic hyperplasia (BPH). Patients and Methods We retrospectively reviewed patients aged >40 years who underwent HoLEP at our institution from 2007 to 2022. Criteria for MetS were diagnoses of at least three of the following: diabetes mellitus, hypertension, hyperlipidaemia, or obesity (body mass index ≥30 kg/m 2 ). Uni‐ and multivariable logistic regression were used to compare the likelihood of immediate, 30‐day, and 90‐day complications between groups. Results A total of 1500 patients were included with a median (interquartile range) age of 70 (65–76) years. Patients with MetS were more likely to develop complications at both 30 and 90 days, including urinary incontinence, irritative voiding symptoms, and bleeding ( P < 0.001). After adjusting for potential confounders, patients with MetS had a greater than three times odds of both 30‐ and 90‐day complications compared to patients without MetS (30‐day adjusted odds ratio [aOR] 3.32, 95% confidence interval [CI] 2.21–5.01, P < 0.001; and 90‐day aOR 3.64, 95% CI 2.49–5.31, P < 0.001). Conclusion Metabolic syndrome was associated with a three‐fold likelihood of 30‐ and 90‐day complications after HoLEP. This could be an important factor to consider in preoperative counselling and patient selection.

Background: Postoperative stress urinary incontinence (SUI) after Holmium Laser Enucleation of the Prostate (HoLEP) has improved with the early apical release (EAR) technique. However, some patients develop SUI despite using EAR HoLEP. The aim of this study is to investigate whether a novel classification of the external sphincter is correlated with postoperative SUI. Methods: The data of 98 patients who underwent EAR HoLEP for benign prostatic hyperplasia were prospectively analyzed. We propose a novel endoscopic classification of external sphincter appearance after HoLEP graded from 0 (best preserved) to 3 (most degraded). Patients were followed for 6 months postoperatively and administered validated questionnaires. A logistic regression was performed to compare moderate SUI rates at sphincter grade 3, controlling for age, obesity, catheter dependency, and grams resected at 6 weeks and 3 months. Results: The sphincter grades included 6 grade 0, 47 grade 1, 30 grade 2, and 15 grade 3. Patients were divided into a group without SUI ( n = 51), and a group with SUI ( n = 47) at 6 weeks postoperatively by International Consultation on Incontinence Questionnaire (ICIQ). Patients with reported SUI on ICIQ were more likely to have sphincter grades ≥2 at 6 weeks (p= 0.001) and 3 months ( p < 0.0001). At 6 months, persistent SUI was associated with sphincter grade 3 ( p < 0.0001). Logistic regression demonstrated that sphincter grade 3 was associated with clinically significant SUI at 3 months ( p < 0.01). Conclusions: Lower sphincter grades are associated with improved return of continence after EAR HoLEP.

Purpose: The Manufacturer and User Facility Device Experience database contains anonymous, voluntary medical device reports. A review of device-related adverse events associated with Benign Prostatic Hyperplasia surgeries was completed. The objective was to evaluate the occurrence and contributing factors to clinically significant complications in a cohort of patients electing to undergo surgical intervention for Benign Prostatic Hyperplasia. Methods: The Manufacturer and User Facility Device Experience database was queried for “Aquablation, Greenlight Laser, Holmium Laser, Morcellator, Water Vapor Thermal Therapy, Loop Resection, and Prostatic Urethral Lift” from 2018 through 2021. A complication classification system (Level I–IV) based on the Clavien-Dindo system was used to categorize events. These events were then correlated with procedural technology malfunctions and classified as “device related” and “non-device related.” Chi squared analysis was performed to identify associations between procedural technology and complication classification distribution. Results: A total of 873 adverse events were identified. The adverse events were classified into level I (minimal harm) versus levels II–IV (clinically significant). Aquablation ( p < 0.017) and Water Vapor Thermal Therapy ( p < 0.012) were associated with a higher proportion of reports with Level II-IV complications compared with other procedure types. Level II-IV complications were not associated with a reported device related malfunction. Conclusions: Aquablation and water vapor thermal therapy demonstrated noteworthy clinically significant complications which were not driven by device-related malfunctions.
