Abstract

Purpose

Lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) are amongst the most commonly treated conditions by urologists. Minimally invasive therapies for the treatment of BPH/LUTS have garnered increased interest as new technology has emerged, improving durability, efficacy, and safety. This paper reviews the most recent literature regarding water vapor therapy, a convective thermal therapy that ablates prostatic tissue.

Recent Findings

The current literature includes a pilot study of 65 men and a randomized controlled trial (RCT) of 197 men investigating the efficacy and safety profile of water vapor therapy up to 2 years. Subjects treated with water vapor therapy demonstrated a 51% reduction in IPSS from baseline, sustained at 24 months (p < 0.0001). Durable improvements in max flow rate (Qmax) and quality of life (QoL) were also achieved, while no changes in sexual function were observed. Reporting of adverse events (AEs) reveals predominantly Clavien grade I complications that were self-limited.

Summary

The clinical efficacy and safety of water vapor therapy are durable to 24 months making it an attractive alternative for patients seeking a minimally invasive treatment for LUTS due to BPH.
