Influence of Prostate Volume on the Incidence of Complications and Urinary Incontinence Following Thulium Fiber Laser Enucleation of the Prostate: Results from Multicenter, Real-world Experience of 2732 patients

Background: The use of the new thulium fiber laser in enucleation of the prostate (ThuFLEP) has been introduced recently. Objective: To evaluate complications and urinary incontinence (UI) after ThuFLEP in small and large prostate volume (PV). Design setting and participants: We retrospectively reviewed patients who underwent ThuFLEP in six centers (from January 2020 to January 2023). The exclusion criteria were concomitant lower urinary tract surgery, previous prostate/urethral surgery, prostate cancer, and pelvic radiotherapy. Outcome measurements and statistical analysis: Patients were divided into two groups: group 1: PV ≤80 ml; group 2: PV >80 ml. Univariable and multivariable logistic regression analyses were performed to evaluate the independent predictors of overall UI. Results and limitations: < 0.01) was the only factor significantly associated with higher odds of UI. A limitation of this study was its retrospective nature. Conclusions: Complications and UI rates following ThuFLEP were similar in patients with a PV up to or larger than 80 ml except for the blood transfusion rate that was higher in the latter. Patient summary: In this study, we looked at outcomes after thulium fiber laser in enucleation of the prostate stratified by PV. We found that blood transfusion was higher in men with PV >80 ml, but urinary incontinence was similar.
