Abstract
BACKGROUND: Water vapor thermal therapy (Rezūm) is a minimally invasive treatment for benign prostatic enlargement (BPE). We report on safety and efficacy of this method for treatment of recurrent urinary retention and relief of catheter dependency owing to BPE in multimorbid patients, considered unfit for surgery. METHODS: We retrospectively evaluated 136 patients with recurrent urinary retention who underwent water vapor therapy in an ambulatory setting with periprostatic block and optional sedation between 11/2017 and 02/2021 in three urological departments. The objective was successful catheter withdrawal and continuing catheter independency after 3- and 12-months following treatment. RESULTS: Mean patient age was 80.3 years (±7.8), mean prostate volume 54 ml (±27.3), and mean catheter dependency before treatment was 4.8 months (±6.0). ASA classification was a followed: II: 10%, III: 71%, and IV: 19%. All procedures were performed successfully in an ambulatory setting. Perioperative complications were infrequent and minor (Clavien-Dindo Grade 1-2) and included haematuria in 4.4% and urinary tract infection in 3.9% of all cases. A total of 103 patients (78.6%) were able to void spontaneously after a median of 31 days. No significant differences in age, prostate volume, duration of catheter dependency, vapor injections, and ASA score were found between patients with successful or unsuccessful outcome. The mean follow-up period was 6.1 months (±5.9, range 1-22 months). A 3-month follow-up was available for 77 patients (75%) and 34 patients (33%) were followed for 12 months. After 3 and 12 months, 93.5 and 91% of patients remained catheter independent. Fifteen patients (11%) died during follow-up, with a mean overall survival of 7.7 months (±4.7). CONCLUSIONS: Water vapor therapy may prove to be a useful, minimally invasive treatment in a multimorbid population with catheter dependency after urinary retention, secondary to BPE, considered at highest risk or unfit for surgery. Future studies are warranted.
