Objectives: This study aims to evaluate the impact of anterior fibromuscular stroma preserved enucleation (AFSPE) of the prostate on serum testosterone levels in patients with benign prostatic obstruction (BPO) and to explore age‐related differences in postoperative testosterone elevation. Methods: In a retrospective analysis, 304 patients from a pool of 560 who underwent AFSPE at Linkou Chang Gung Memorial Hospital between January 2018 and December 2021 were evaluated. Patients were stratified based on preoperative testosterone levels into low (<3.5 ng/mL) and normal (≥3.5 ng/mL) groups. Serum testosterone levels were measured preoperatively, at 1.5 and 3–6 months postoperatively. Age and other demographic data were analyzed as potential factors influencing testosterone changes. Results: The low‐testosterone group (n = 90) showed significant testosterone increases, from an average of 2.61 ng/mL preoperatively to 3.3 ng/mL at 1.5 months and 3.59 ng/mL at 3–6 months postoperatively (p < 0.0001). The normal‐testosterone group (n = 214) maintained stable testosterone levels at 1.5 months but exhibited a significant rise to 6.06 ng/mL by 3–6 months (p = 0.0079). Older age was inversely associated with postoperative testosterone elevation in both groups. Improvements in nocturia were notable in both groups. Conclusions: AFSPE of the prostate significantly elevates serum testosterone levels in men with BPO, particularly benefiting those initially with low levels. Age is a crucial factor influencing postoperative testosterone changes, indicating that younger patients may benefit more from this intervention. AFSPE offers a promising approach for improving hormonal health in BPO patients, alongside alleviating urinary symptoms. [ABSTRACT FROM AUTHOR]

Purpose: Postoperative urinary retention (PUR) is a common complication after prostate enucleation, which leads to an increased length of hospital stay and decreased postoperative satisfaction. This study determined the predictive factors of postoperative urine retention within 1 month after prostate enucleation and investigated whether PUR influences surgical outcomes at the 2-week, 3-month, and 6-month follow-up time points. Methods: Data were collected from the electronic medical records of 191 patients with benign prostatic obstruction (BPO) during October 2018 to September 2021. Of them, 180 patients who underwent thulium laser or plasma kinetic enucleation of the prostate (ThuLEP, PKEP) were separated into the PUR group (n = 24) and the non-PUR (NPUR) group (n = 156). Uroflowmetry and the International Prostate Symptom Score (IPSS) questionnaire were followed up at 2 weeks, 3 months, and 6 months postoperatively. Results: The PUR group had a significantly higher percentage of patients with type 2 diabetes mellitus (DM) than the NPUR group. Postoperatively, compared with the NPUR group, the PUR group had significantly less improvement in changes in the IPSS Quality of Life scores at 2 weeks, the total IPSS(International Prostate Symptom Score) at all follow-up times, the IPSS-S(IPSS storage subscores) at 2 weeks and 3 months, and the IPSS-V(IPSS voiding subscores) at all follow-up times. Predictive factors for PUR include lower preoperative maximum urinary flow (Qmax), lower preoperative total IPSS, and higher operation time. Conclusion: Lower preoperative Qmax, lower IPSS scores, and longer operation time were risk factors for PUR. Furthermore, PUR could be a prognostic factor for prostatic enucleation surgical outcomes.

Bleeding during endoscopic prostate surgery is often overlooked, and appropriate measurement techniques are rarely applied. We proposed a simple and convenient method for assessing the severity of bleeding during endoscopic prostate surgery. We determined the factors affecting bleeding severity and whether they affected the surgical results and functional outcomes. Records from March 2019 to April 2022 were obtained for selected patients who underwent endoscopic prostate enucleation through either 120-W Vela XL Thulium:YAG laser or bipolar plasma enucleation of the prostate. The bleeding index was measured using the following equation: irrigant hemoglobin (Hb) concentration (g/dL) × irrigation fluid volume (mL)/preoperative blood Hb concentration (g/dL) × enucleated tissue (g). Our research revealed that patients who underwent surgery employing the thulium laser, those aged over 80 years, and those with a preoperative maximal flow rate (Qmax) of more than 10 cc/s experienced less surgical bleeding. The patients' treatment outcomes differed depending on the severity of the bleeding. Enucleating prostate tissue was easier in the patients with less severe bleeding, who also had a lower risk of developing urinary tract infections and an improved Qmax. [ABSTRACT FROM AUTHOR]
