Comparison of postoperative functional results in holmium laser enucleation of the prostate, green laser photovaporization of the prostate and transurethral resection of the prostate in the treatment of obstructive prostatic hyperplasia

Abstract

Objective: To compare the functional results in patients undergoing transurethral resection of the prostate (TURP), photovaporization of the prostate with GreenLight ® laser (FTV) and prostate enucleation with Holmium laser (HOLEP), for the treatment of benign prostatic obstruction at the Central Military Hospital. Material and methods: The international index of prostate symptomatology questionnaire (IPSS), Uroflowmetry (Qmax), pre and post void ultrasonography (PVR) were applied to patients undergoing TURP, VTF and HOLEP pre and postoperatory from January 2018 to March 2019. Shapiro-Wilks tests were analyzed for quantitative variables; parametric behavioral data were analyzed with ANOVA tests, and non-parametric data were analyzed with Mann-Whitney and Kruskal-Wallis U tests. GraphPad PRISM v7.0 statistical package was used. Results: 46 patients underwent to TURP, 62 to HOLEP and 17 to VFT were evaluated, removing those who did not achieve complete postoperative follow-up; describing the demographic characteristics, the most frequent comorbidities and the parameters evaluated preoperatively. At follow-up, HOLEP was slightly better than FTV or TURP; without finding statistical significance between the groups, observing an important improvement in the reference values of IPSS, Qmax and PVR after surgery in all populations. Conclusions: No superiority of any technique was proven in short-term postoperative functional results, so we propose to perform long-term studies, considering adding trans and postoperative parameters in order to demonstrate superiority of these techniques.
