Holmium laser enucleation of the prostate: Modified urethral mucosa pre-dissected technique versus traditional three-lobe technique-A retrospective study.
Objective: The aim of this study is to investigate the effect of modified holmium laser enucleation of the prostrate (HoLEP) on the function of urine control.
Methods: An analysis was conducted on a cohort of 305 elderly patients in a retrospective study spanning from February 2019 to February 2023. The cohort consisted of 150 patients who underwent modified HoLEP and 155 patients who underwent traditional HoLEP. Factors such as age, length of membranous urethra, prostate volume, BMI, IPSS, Qmax, enucleated weight, enucleation time, post-operative bladder irrigation time, catheterization and hospitalization were compared between both the groups. Multivariable logistic regression was used to identify independent predictors of urinary incontinence, and receiver operating characteristic (ROC) curve was used to determine the sensitivity and specificity of urethral membrane length in the diagnosis of urinary incontinence. Postoperative Qmax,IPSS, V2 were compared between 2 groups in the 6th month.
Results: Groups were compared in terms of age, volume, BMI, IPSS, Qmax and membranous urethral length (MUL). The time of enucleation, bladder irrigation, post-operative catheterization and hospitalization was lower in the modified HoLEP group (p < 0.05). The incidence of urinary incontinence (UI) in the modified group had a statistically significant decrease at 3 months (3.3% vs 9.7%, p = 0.025) and 6 months (0.6% vs 5.2%, p = 0.048). The median MUL had a significant difference in the 1st month (15.07 vs 12.5 mm, p < 0.001). In multivariate regression analysis, older age (OR per SD = 1.102, 95%CI: 1.077-1.136), shortened MUL (OR per SD = 0.776, 95%CI: 0.629-0.957) and increased enucleated prostate weight (OR per SD = 1.29,95%CI: 1.005-1.084) were significantly associated with UI. The ROC curve revealed the threshold value of MUL was 13.5 mm, the sensitivity was 76.7%, and the specificity was 98.1%.
Conclusion: The modified HoLEP technique is safe and effective on the function of urine control, and is superior to less residual prostate volume and higher maximum urine flow rate after surgery.
期刊介绍：
Lasers in Medical Science (LIMS) has established itself as the leading international journal in the rapidly expanding field of medical and dental applications of lasers and light. It provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of medical lasers, including lasers in surgery, endoscopy, angioplasty, hyperthermia of tumors, and photodynamic therapy. In addition to medical laser applications, LIMS presents high-quality manuscripts on a wide range of dental topics, including aesthetic dentistry, endodontics, orthodontics, and prosthodontics.
The journal publishes articles on the medical and dental applications of novel laser technologies, light delivery systems, sensors to monitor laser effects, basic laser-tissue interactions, and the modeling of laser-tissue interactions. Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
