Study of risk factors of early reintervention after prostate laser photovaporization using Greenlight 180 W-XPS.

Background

Greenlight laser prostate photovaporization (PVP) is an alternative treatment for benign prostatic hyperplasia.

Purpose

The aim of our study was to identify the risk factors for reintervention due to recurrent obstruction within 12 months following a photovaporization.

Methods

This retrospective, multicenter cohort study include patients treated with laser Greenlight 180W-XPS.

n = 777 patients

Results

Beyond 4000 J/ml, the odds of reintervention are 90% lower.

OR by subgroup · 95% CI

More results

Groups were comparable on preoperative data.

These factors were associated with a reduced risk of reintervention.

“

Conclusion · 1 of 2

PVP shows a low complication rate. Our results suggest that the energy delivered and the laser emission time are predictive of the quality of treatment.

Conclusion · 2 of 2

Despite uncertainties regarding this technique, our findings provide urologists with additional confidence in its use and offer predictive factors for assessing treatment's quality.

Post
