Photoselective vaporization of the prostate with the 180-W XPS-Greenlight laser: Five-year experience of safety, efficiency, and functional outcomes.

Introduction: Transurethral resection of the prostate (TURP) is still considered the gold standard surgical treatment for symptomatic benign prostatic hyperplasia (BPH). However, photoselective vaporization of the prostate (PVP) has gained widespread global acceptance in national guidelines as a safe and effective alternative option. Nevertheless, further evidence is required to assess the durability of Greenlight PVP.

Introduction: A variety of techniques are available for proximal hypospadias repair. Onlay, proximal tubularized incised plate (TIP), and Duckett are among the popular choices because they can be performed as a one-step procedure. However, the decision to select a procedure often comes down to the surgeon's preference rather than that supported by evidence-based data.

Introduction: We assessed the incidence of contralateral prostate cancer (cPCa), contralateral EPE (cEPE) and contralateral positive surgical margins (cPSM) in patients diagnosed preoperatively with unilateral prostate cancer and evaluated risk factors predictive of contralateral disease extension.

Methods: The occurrence of cPCa, cEPE and cPSM and the side-specific nerve-sparing technique performed were collected postoperatively from 327 men diagnosed with unilateral prostate cancer at biopsy. Parameters, such as the localization, proportion, and percentage of cancer in positive cores, were prospectively collected.

Introduction: We evaluated the average time required to complete individual steps of robotic-assisted radical prostatectomy (RARP) by an expert RARP surgeon. The intent is to help establish a time-based benchmark to aim for during apprenticeship. In addition, we aimed to evaluate preoperative patient factors, which could prolong the operative time of these individual steps.
