ABSTRACT
Benign prostatic hyperplasia (BPH) is prevalent in older men. As surgery can be high risk in this group, minimally invasive procedures are preferrable. This study aimed to assess the initial results of minimally invasive Rezum water vapor thermal therapy (WVTT) in patients with BPH. This single-center retrospective study included 25 consecutive patients with BPH who underwent WVTT between September 2022 and July 2023. Parameters including age, Charlson Comorbidity Index and Geriatric 8 (G8) scores, operative time, and number of vapor injections were evaluated. The International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score, and Core Lower Urinary Tract Symptom Score (CLSS) were used to assess symptoms before the procedure, and at 1 and 3 months after it. Urinary function indicators such as single voiding volume, maximum flow rate (MFR), and post-void residual volume were assessed at the same time points. The mean patient age was 76.0 years and the mean prostate volume was 54.8 mL. The mean G8 score was 14.4 and the Charlson Comorbidity Index score averaged 1.2. The mean operative time was 6.84 min, and included a mean of 4.8 vapor injections. Three months after WVTT, significant improvements were observed in the maximum flow rate (Pâ
=â
.02), post-void residual volume (Pâ
=â
.001), and urine volume (Pâ
<â
.001), as well as in the IPSS incomplete emptying (Pâ
=â
.01) and weak stream (Pâ
=â
.01) domains. No significant changes were observed in the remaining IPSS domains or in the Overactive Bladder Symptom Score or CLSS. This study provides the first report on Rezum WVTT outcomes in Japan using the CLSS assessment tool. The initial results indicate a promising experience with this new treatment method. With a rapidly aging population, the incidence of BPH is expected to increase, making the minimally invasive Rezum system a valuable addition to BPH treatment options.
