Summary

Today, endoscopic enucleation of the prostate (EEP) has been recognized a method of choice for treatment of benign prostatic hyperplasia (BPH) of any size, including large-sized glands (\>80 cc). The goal of our study was to compare perioperative efficacy, functional outcomes and safety of different techniques of endoscopic enucleation of the prostate (monopolar enucleation, holmium laser enucleation, thulium laser enucleation) in a single center.

Detailed description

HoLEP and ThuLEP or EEP have been approved by the current guidelines of the European Association of Urology for use in men with substantially enlarged prostates (\>80 ml) as first-line therapy \[1\]. This type of operation can be performed by means of several sources of energy. To our knowledge, there were no studies comparing efficacy and complications of these three treatment modalities. In this study the investigators have evaluated efficacy of Thulium-fiber laser enucleation (120 W thulium fiber laser Urolase, IPG IRE-POLUS, Russia with wavelength of 1940 nm) and monopolar enuclation in comparision with HoLEP (VersaPulse Powersuite 100, Lumenis, USA/Israel) in reduction of LUTS secondary to BPH in a prospective randomized trial. All peri-operative parameters, urinary flow parameters, prostate size changes, erectile function and complications associated with the procedures were compared.

Conditions

• Prostatic Hyperplasia, Benign
• Prostate Adenoma
• Lower Urinary Tract Symptoms

Interventions

Type	Name	Description
PROCEDURE	Thulium-fiber laser enucleation of the prostate	A high-power (120 W) thulium fiber laser (Urolase, IPG IRE-POLUS, Russia) with wavelength of 1940 nm was used for thulium laser enucleation. In our study, we used a 600-μm laser fiber. The operations were performed at power of 60 W energy of 1.5 J and repetition rate of 40 Hz. Laser power in the verumontanum zone was decreased to 30 W and repetition rate to 20 Hz.
PROCEDURE	Monopolar enucleation of the prostate	Monopolar enucleation was performed with a high-frequency generator (50-60 Hz), a pusher-electrode, and a hook-electrode.
PROCEDURE	Ho:YAG laser enucleation of the prostate	Holmium laser enucleation of prostatic hyperplasia was performed with a 100 W laser (VersaPulse Powersuite 100, Lumenis, USA/Israel) with wavelength of 2100 nm and 550-μm fiber at the tip. The operation was performed at power of 70 W; it was decreased to 40 W when incisions were made at the verumontanum.
