Aim: The aim of our study was to evaluate efficiency of thulium laser enucleation of the prostate (ThuLEP) for the treatment of benign prostatic hyperplasia (BPH).
Materials And Methods: A retrospective analysis of 112 patients with BPH who underwent ThuLEP (n=60) or holmium laser enucleation of the prostate (HoLEP) (n=52) at our institution from January 2017 to June 2017 was carried out. The perioperative data and complication rate were assessed. Severity of lower urinary tract symptom (LUTS) was evaluated after 1, 6 and 12 months using International Prostate Symptom Score [I-PSS], quality-of-life [QoL] score and maximum flow rate [Qmax]. To shorten learning curve, we modified the technique and simplified the intervention. To reduce noise during surgery, we performed ThuLEP using Vela XL.
Results: There were significant differences in pre- and perioperative parameters, including operative time (113.15+/-12.14 vs. 118.08+/-15.76 min, p=0.46), decrease in serum sodium concentration (3.49+/-0.83 vs. 3.48+/-0.84 mmol/L, P=0.97), hemoglobin drop (1.37+/-0.18 vs. 1.43+/-0.38 g/dL, p=0.65), catheterization time (2.15+/-0.38 vs. 2.27+/-0.39 days, p=0.52) and hospital stay (6.95+/-0.82 vs 7.56+/-1.36 days, p=0.25) between the two groups (ThuLEP and HoLEP). Compared with the HoLEP group, intraoperative noise was lower in ThuLEP group (47.22+/-10.31 vs. 59.45+/-9.65 db, p<0.05). At 1-, 6- and 12 months follow-up, the LUTS severity (I-PSS, QoL score and Qmax) were significantly improved in both groups in comparison with the baseline values. Furthermore, there was no difference in LUTS severity between two groups (p>0.05).
Conclusion: ThuLEP is comparable to the holmium laser in terms of efficiency, safety and indications and represent minimally invasive treatment option for patients with LUTS secondary to BPH.

Water vapor thermal therapy for treatment of lower urinary tract symptoms due to large benign prostatic hyperplasia (≥ 80 g).

Introduction: Water vapor thermal therapy (WVTT; REZUM™; Boston, USA) offers symptom relief with reduced risks of complications in patients with lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO). WVTT therapy has been validated in the pivotal study in men with smaller prostates (< 80 cc). Yet, its feasibility for larger prostates (≥ 80 cc) remains underexplored.

Introduction And Objective: Urodynamic study (UDS) is required to diagnose bladder outlet obstruction (BOO) during evaluation of benign prostatic hyperplasia (BPH) but is seldom performed due to cost and invasiveness. Therefore, anatomic and clinical parameters to predict BOO have been proposed, including the prostate transition zone index (TZI) which is the ratio of prostate transition zone volume (TZV) to whole gland volume (WGV). Historically computed with ellipsoid volume estimation of prostate WGV and TZV from transrectal ultrasound measurements, controversy exists regarding the utility of TZI to predict likelihood of BOO on UDS and clinical outcomes following BPH surgery.

Objectives: During holmium laser enucleation of the prostate (HOLEP), blunt dissection (BD) by pushing the tip of the scope may exert mechanical force on the sphincter that could be avoided by adopting laser dissection (LD). This study evaluates the continence recovery in consecutive patients who underwent BD and LD.
Methods: A prospective cohort of patients who underwent LD was compared with a retrospective control that underwent BD.

Background And Purpose: Though TURP remains the primary treatment for BPH, advancements in energy and technology have introduced innovative transurethral surgical options. In this study, we assessed and compared the effectiveness and safety of using thulium laser and bipolar for endoscopic enucleation of prostate exceeding 80 g.
Patients And Methods: Between January 2022 and July 2023, this study enrolled patients with LUTS due to BPH and a prostate size of ≥80 g.
