Transurethral enucleation (TUE) has revolutionized the management of benign prostatic obstruction (BPO), offering a minimally invasive solution with superior efficacy across all prostate sizes. This review explores the advancements in TUE techniques, including Holmium Laser Enucleation of the Prostate (HoLEP), Thulium Laser Enucleation of the Prostate (ThuLEP), and bipolar enucleation, highlighting their clinical benefits, safety profiles, and long-term outcomes. Compared to traditional approaches such as transurethral resection of the prostate (TURP) and open prostatectomy, TUE has been associated with reduced complication rates, shorter recovery times, and durable symptom relief. The manuscript also examines patient-centered considerations, such as quality of life improvements and preservation of sexual function, which contribute to high patient satisfaction. Furthermore, the economic advantages of TUE, driven by reduced retreatment rates and healthcare costs, underscore its value for both patients and healthcare systems. Emerging innovations, including artificial intelligence (AI), promise to further enhance procedural planning, surgical precision, and training pathways. Efforts to expand global access through cost-effective adaptations like bipolar enucleation and targeted training initiatives are paving the way for wider adoption of TUE. With its adaptability, technological advancements, and focus on patient outcomes, TUE is poised to become the global standard of care in BPO management. Full article

Background and Objectives: Benign prostatic hyperplasia is a common condition among aging men, leading to bladder outlet obstruction and associated lower urinary tract symptoms. Surgical intervention, particularly endoscopic enucleation of the prostate, has become increasingly popular over traditional methods such as transurethral resection of the prostate. However, urethral strictures remain a major postoperative complication. This study evaluated the incidence, risk factors, and clinical outcomes of urethral strictures after endoscopic enucleation of the prostate. Materials and Methods: This study retrospectively analyzed prospectively collected data from 246 patients who underwent either thulium laser enucleation of the prostate or bipolar transurethral enucleation of the prostate at Chang Gung Memorial Hospital between October 2018 and December 2022. Patients were evaluated preoperatively using uroflowmetry, International Prostate Symptom Score (IPSS), and other relevant clinical metrics. Follow-up assessments at 2 weeks, 3 months, and 6 months post-surgery included uroflowmetry, IPSS evaluation, and cystoscopy when indicated. A urethral stricture was deemed to be present if a 5.5 mm fiber cystoscope was unable to pass through the urethra. Results: Of the 246 patients, 23 (9.3%) developed urethral strictures, with the membranous urethra being the most common site (69.2%). Patients with strictures had significantly smaller prostate volumes and enucleated tissue weights, higher trial without catheter (TWOC) failure rates, and a higher postoperative urinary tract infection (UTI) incidence. Multivariate analysis identified smaller prostate size, lower resected tissue weight, TWOC failure, and postoperative UTI as significant risk factors for stricture formation. The type of energy source used for enucleation (bipolar or Thulium laser) was not identified as a factor influencing the incidence of urethral stricture. Conclusions: Urethral strictures constitute a major complication following endoscopic enucleation of the prostate, particularly in patients with smaller prostates and those experiencing postoperative complications such as UTIs and TWOC failure. These findings underscore the importance of careful surgical technique and rigorous postoperative monitoring to reduce the incidence of this complication. Full article

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. Full article

Background and Objectives: The study investigated whether the method of achieving hemostasis affects the ovarian reserve in patients undergoing laparoscopic surgery due to ovarian tumors or cysts. Materials and Methods: Patients with unilateral tumors or ovarian cysts, who qualified for laparoscopic tumor enucleation, were randomly selected to receive modified polysaccharides or bipolar coagulation. Ovarian reserve was analyzed by anti-Mullerian hormone (AMH) level. Results: The study included 38 patients: 19 patients in the modified polysaccharide group and 19 in the bipolar coagulation group. Patients after bipolar coagulation treatment had statistically significantly lower AMH 6 months after surgery compared to the group treated with modified starch. The levels of AMH in the study and control groups were 3.96 +/− 2.12 vs. 2.51 +/− 1.39 ng/mL, respectively; p = 0.018. A statistically significant decrease in AMH was also demonstrated in the bipolar coagulation group as compared to the preoperative assessment (p = 0.049). There was no statistically significant decrease in AMH in the group of patients treated with the modified starch. Conclusions: Using a modified polysaccharide during laparoscopic cystectomy is effective and has a positive effect on the ovarian reserve compared to the use of bipolar coagulation. Both the AMH level 6 months after surgery and the percentage decrease in AMH were more favorable in the group of patients treated with modified starch. Full article

Background: We evaluated the impact of endoscopic enucleation of the prostate on testosterone levels in hypotestosteronemic patients with bladder outlet obstruction. Methods: We enrolled 294 men with lower urinary tract symptoms (LUTS) who received surgery between January 2019 and December 2020 in simple tertiary centre. The inclusion criteria were as follows: being a male patient aged 45–95 years and having recurrent urinary tract infection, having previously failed medical treatment for LUTS or urine retention, and undergoing bipolar or thulium laser enucleation of the prostate. The preoperative and postoperative data were retrospectively reviewed. Results: This study included 112 men with a mean age of 69.4 years. The mean preoperative and postoperative testosterone levels were 4.8 and 4.98, respectively. Of the patients, 88 (78.6%) received ThuLEP and 24 received BipolEP. We divided the patients into two groups according to preoperative serum testosterone levels: normal-testosterone (≥3 ng/mL) and low-testosterone (<3 ng/mL) groups. A significant change in testosterone levels (p = 0.025) was observed in the low-testosterone group. In contrast, no significant difference in testosterone levels was noted in the normal-testosterone group (p = 0.698). Conclusions: Endoscopic enucleation surgery of the prostate could improve postoperative testosterone levels in hypotestosteronemic patients with bladder outlet obstruction. Full article

Benign prostate hyperplasia (BPH) refers to the nonmalignant enlargement of the transition zone of the prostate gland. While holmium laser enucleation of the prostate and open simple prostatectomy are effective in the management of patients with large prostates, they have some limitations. Thus, this study aimed to analyze the efficacy and safety of the sandwich method of bipolar transurethral resection of the prostate (B-TURP) and GreenLight photoselective vaporization of the prostate (GLPVP) in patients with large prostates. Patients diagnosed with BPH who underwent the sandwich method with B-TURP and GLPVP from 2015 to 2020 were included. Efficacy analyses included the change in the uroflowmetry results in both group A (prostate volume < 80 g) and group B (prostate volume ≥ 80 g), and complication analyses included perioperative complications, early postoperative complications at three months and late postoperative complications at 12 months. The cohort comprised 188 and 44 patients in groups A and B, respectively. The prostate volume of groups A and B were 50.83 ± 14.14 g and 102.03 ± 19.36 g (p < 0.001), respectively. The peak (Q_max) and average (Q_avg) flow rates were comparable between the two groups. The only significant difference noted was in the postoperative post-void residual (PVR) urine. Improvement was seen in all the variables including the Q_max, Q_avg and PVR urine in each group. No patient experienced perioperative complications. Analysis of the overall one-year complication rate showed no significant difference between the two groups. The sandwich method of B-TURP and GLPVP may be feasible for the management of patients with large prostate. Full article

(1) Background: To critically evaluate dorsal onlay buccal mucosal graft urethroplasty (DOBMGU) for posterior urethral stenosis repair following transurethral resection and other endoscopic prostate procedures. (2) Methods: A retrospective multi-institutional review of patients with membranous or bulbomembranous urethral stenosis for whom treatment with DOBMGU was conducted after receipt of prostate endoscopic procedures. Baseline data, peri-operative care, post-operative care and patient-reported outcomes were analyzed. The primary outcomes were procedural failure and development of de novo stress urinary incontinence (SUI). The secondary outcomes were changes in voiding, sexual function and patient satisfaction. (3) Results: A total of 107 men with a mean age of 69 ± 9.5 years and stenosis length of 3.5 ± 1.8 cm were included. Prior endoscopic procedures among participants were 47 patients (44%) with monopolar TURP, 33 (30.8%) with bipolar TURP, 16 (15%) with Greenlight laser, 9 (8.4%) with Holmium laser enucleation and 2 (1.9%) with bladder neck incision. At a mean follow-up time of 59.3 ± 45.1 months, stenosis recurred in 10 patients (9.35%). Multivariate analysis confirmed that postoperative complications (OR 12.5; p = 0.009), history of radiation (OR 8.3; p = 0.016) and ≥2 dilatations before urethroplasty (OR 8.3; p = 0.032) were independent predictors of recurrence. Only one patient (0.9%) developed de novo SUI. Patients experienced significant improvement in PVR (128 to 60 cc; p = 0.001), Uroflow (6.2 to 16.8 cc/s; p = 0.001), SHIM (11.5 to 11.7; p = 0.028), IPSS (20 to 7.7; p < 0.001) and QoL (4.4 to 1.7; p < 0.001), and 87 cases (81.3%) reported a GRA of + 2 or better. (4) Conclusions: DOBMGU is an effective and safe option for patients with posterior urethral stenosis following TURP and other prostate endoscopic procedures. This non-transecting approach minimizes external urinary sphincter manipulation, thus limiting postoperative risk of SUI or erectile dysfunction. Full article

The acronym EEP, coding for transurethral Endoscopic Enucleation of the Prostate, was introduced in 2016 by the European Association of Urology (EAU) guidelines panel on management of non-neurogenic male lower urinary tract symptoms (LUTS) and benign prostatic obstruction (BPO). Since then, a laser-based treatment, Holmium Laser Enucleation of the Prostate (HoLEP), and the current-based treatment of bipolar enucleation of the prostate (BipoLEP) are equally appreciated as valuable options for the management of benign prostatic obstruction (BPO). This was mainly inspired by the results of two meta-analyses on randomized controlled trials, comparing open prostatectomy with either Holmium Laser Enucleation of the Prostate (HoLEP) or bipolar enucleation of the prostate (BipoLEP). Prior to that, HoLEP was embraced as the only valid option for transurethral enucleation, although evidence for equivalence existed as early as 2006, but was not recognized due to a plethora of acronyms for bipolar energy-based treatments and practiced HoLEP-centrism. On the other hand, the academic discourse focused on different (other) laser approaches that came up, led by Thulium:Yttrium-Aluminum-Garnet (Tm:YAG) Vapoenucleation (ThuVEP) in 2009 and, finally, transurethral anatomical enucleation with Tm:YAG support (thulium laser enucleation of the prostate, ThuLEP) in 2010. Initially, the discourse on lasers focused on the different properties of lasers rather than technique or surgical anatomy, respectively. In and after 2016, the discussion ultimately moved towards surgical technique and accepting anatomical preparation as the common of all EEP techniques (AEEP). Since then, the unspoken question has been raised, whether lasers are still necessary to perform EEP in light of existing evidence, given the total cost of ownership (TCO) for these generators. This article weighs the current evidence and comes to the conclusion that no evidence of superiority of one modality over another exists with regard to any endpoint. Therefore, in the sense of critical importance, AEEP can be safely and effectively performed without laser technologies and without compromise. Full article

Bipolar plasma vaporization of the prostate (BPVP) is an attractive alternative to resection. There are numerous studies comparing transurethral resection of prostate or photoselective vaporization of the prostate with BPVP; however, there is a lack of data comparing holmium laser enucleation of the prostate (HoLEP) with BPVP. We aimed to compare HoLEP and BPVP with a focus on functional outcomes, safety, and complications. Methods: From January 2017 to June 2018, patients who underwent HoLEP or BPVP for benign prostatic hypertrophy were enrolled in this study. Inclusion criteria were a prostate volume <40 mL measured by transrectal ultrasound, international prostate symptom score (IPSS) >7, maximum urinary flow rate (Qmax) <15 mL/s, and postvoiding residual volume (PVR) >100 mL. Perioperative and postoperative parameters including IPSS, Qmax, quality of life, PVR, and complications were compared between groups. Results: Sixty-three patients were enrolled in this study. There were small differences in perioperative parameters. Hospital stays and catheterization periods were significantly shorter in the BPVP group. The postoperative complications were comparable between groups. PVR was comparable in both groups except for 1 month postoperatively. The incontinence rate was higher in the HoLEP group, but without statistical significance. Conclusion: In terms of surgical safety and efficacy as well as patient comfort, BPVP is comparable with HoLEP for small prostate volumes. BPVP can be a viable alternative technique in small BPH surgical treatment. Full article
