We sought to evaluate the effect of a minimal approach of water vapor thermal therapy (Rezum, Boston Scientific, Marlborough, MA, USA), defined as 1 vapor treatment per prostate lobe, on urinary symptoms and quality of life (QOL) compared to patients who received multiple treatments per lobe. METHODS: We performed a single-institution retrospective review of patients who underwent water vapor therapy for the treatment of symptomatic BPH from February 2017 to September 2022. Propensity score matching was utilized to generate patient cohorts based on the number of treatments per lobe (1 per lobe including median lobe if present vs ≥2 per lobe) matched for age, BMI, and pre-operative prostate volume (cc). Primary outcome of interest was post-operative complications and irritative symptoms. Secondary outcomes included differences in International Prostate Symptom Score (IPSS) and QOL sub score at baseline and at 1, 3, 6, and 12 months after the procedure. RESULTS: 146 patients were included in the PSM with 73 patients who received one vapor treatment per lobe and 73 patients receiving 2 or more treatments per lobe. DEMOGRAPHICS TABLE (Table 1a). On MVA, an increasing number of treatments (HR 1.3, p=0.039) and treatment of the median lobe (HR 4.7, p=0.008) were significant risk factors for adverse events after REZUM. On MVA looking at risk of post-op urinary retention, only increasing number of treatments (HR 1.6, p=0.005) was an independent risk factor while use of BPH medications, prostate volume, and median lobe treatment were not (p=0.3-0.72). Patient’s with minimal treatment had improved IPSS total and voiding sub-score at 1 month and non-inferior IPSS scores at 3-, 6-, and 12- month follow-up. CONCLUSIONS: Minimal Rezum treatment approach with a single water vapor injection per lobe is a safe and effective option for patients undergoing long-term treatment for BPH and is associated with improved postoperative complications and irritative voiding symptoms. Further studies are needed to investigate the effect of this minimal approach on longer-term outcomes.
