Abstract
Background:
Endoscopic enucleation of the prostate (EEP) is a safe and effective intervention option for management of variable-sized adenomas.
Purpose:
The aim of this study was to point out the safety and efficacy of bipolar needlescopic enucleation of the prostate (BNEP) in comparison with bipolar vapoenucleation of the prostate (BVEP).
Materials and Methods:
This is a prospective randomized trial. In all, 214 patients with variable size adenoma were randomly assigned (1:1) to either the BNEP group (108 patients who underwent bipolar endoscopic enucleation of the prostate [BEEP] using a needle electrode) or the vapoenucleation (BVEP) group (106 patients who underwent BEEP using vaporization electrodes). Intra- and intergroup objective and subjective outcomes were compared at different time points for 1 year. In addition, all other procedure-related events and mishaps were registered and compared.
Results:
The medians (interquartile ranges) for operative time (OT), resected tissue weight, postoperative irrigation time, and hemoglobin drop were 60 (50–88) vs 80 (60–98) minutes, 67 (56–86) vs 46 (40–61) grams, 10 (8–12) vs 12 (10–18) hours, and 1 (0.6–1.3) vs 1.2 (0.88–1.9) g/dL for BNEP and BVEP groups, respectively (p  0.5). However, the postoperative irritative symptoms and urinary infections were lower in the BNEP group (p
