Transurethral Vapor Enucleation of the Prostate

Abstract

Introduction:

During the last decade, a bipolar plasmakinetic vaporization system with a novel button-like electrode has emerged and was described as a safe and effective option for the treatment of benign prostatic hyperplasia (BPH). Here, we present a modified technique named transurethral vapor enucleation of the prostate (TVEP).

Materials and Methods:

We provide a video that shows the main steps of this procedure. Vapo-enucleation of the prostate is performed by moving the button electrode circumferentially from the verumontanum toward the bladder neck, and the enucleated prostate tissue is retrieved by the morcellator. Three patients who were treated by TVEP in our institution between 2013 and 2014 were retrospectively evaluated to assess its feasibility. The postvoiding residual urine (PVRU) and maximum flow rate (Qmax) were measured preoperatively and 3 months postoperatively.

Results:

The mean operative time was 85 min. Nearly no vascular bleeding was observed during the operation. The average Qmax improved from 7.6 to 18.3 mL/s, and the PVRU decreased from 152 to 17 mL.

Conclusions:

TVEP seems to represent a promising endoscopic treatment alternative for BPH.

No competing financial interests exist.
