Abstract
OBJECTIVES: Various techniques can be used for endoscopic enucleation of the prostate (EEP): removal of all nodes as a single unit (en bloc) or a step-by-step removal of adenomatous nodes (two- and three-lobe techniques). The objective of this study was to perform a comparative analysis of en bloc and two-lobe techniques for holmium laser enucleation of the prostate (HoLEP) and thulium fiber laser enucleation of the prostate (ThuFLEP). METHODS: Retrospective assessment included patients with bladder outlet obstruction (IPSS > 20, Qmax < 10) secondary to BPH treated from January 2013 to December 2018. All the patients were assessed prior to surgery, as well as at 1, 3 and 6 months after surgery. RESULTS: The data of 1115 patients who underwent HoLEP or ThuFLEP were analyzed. Two techniques were used: en bloc (406 patients) and two-lobe (709 patients). Mean prostate volumes were comparable between groups. Mean surgery times (68.8 ± 30.6 min vs 67.4 ± 30.1 min; p = 0.604) and enucleation rates (1.9 ± 0.74 g/min vs 1.9 ± 0.69 g/min; p = 0.217) were also comparable. Morcellation rate was lower in en bloc patients with prostate > 150 cc (2.8 ± 1.1 g/min vs 3.7 ± 2.3 g/min; p < 0.001). At 6 months, no differences in functional outcomes (IPSS, PVR, Qmax and QoL) were found. CONCLUSIONS: Outcomes and complication rates of en bloc and two-lobe EEP techniques were comparable. En bloc technique was found to have less favorable outcomes in morcellation rate for prostates > 150 cc. The choice of the technique should depend on surgeon's preferences.
