Convective Water Vapour Energy Ablation (Rezum®) versus Prostatic Urethral Lift (Urolift®); A 2-Year Prospective Study.

Introduction To compare the clinical outcomes and complication rates of Convective Water Vapour Energy Ablation (Rezum®) and Prostatic Urethral Lift (Urolift®). To identify predictive factors for treatment failures in both treatments. Materials & Methods Prospective clinico-epidemiological data of patients who underwent Urolift® or Rezum® in a single institution for Benign Prostatic Hyperplasia (BPH) was collected. The choice of intervention depended on the preference of the patients after patient-centric discussions. Results From October 2019 to October 2022, 86 patients underwent Rezum® and 62 patients underwent Urolift®. Rezum® involved a longer indwelling catheter duration (12.38±5.548 versus 1.39±3.010 days, p<0.001) compared to Urolift®. Rezum® was associated with more complications compared to Urolift® (36 (41.9%) versus 10 (16.1%) cases, p<0.001). Rezum® had more cases of hematuria (17 (19.8%) versus 4 (6.5%) cases (p=0.022)) and urinary tract infections (27 (31.4%) versus 3 (4.8%) cases, p<0.001)), compared to Urolift®. There were no significant differences in Clavien-Dindo Grade 3-5 complications between the interventions. Urolift® was associated with higher re-operation rates (5 (8.1%) versus 0 (0%) cases, p=0.010) compared Rezum®. Rezum® had higher anti-cholinergic usage rates compared to Urolift® post-operation (22 (25.6%) versus 8 (12.9%) cases, p=0.024). Both interventions showed improvement in International Prostate Symptom Score (IPSS), Quality of Life score, and peak velocity flow over the 2 years with no significant difference between the two. Based on receiver operating characteristic curve, pre-operation IPSS ≥ 16 had 95.7% sensitivity and 38.4% specificity to predict the probability of treatment failures after the interventions. Conclusions There was no difference in clinical outcomes of patients who underwent Rezum® and Urolift®. However, patients who had undergone Rezum® faced more minor complications and more required anti-cholinergic medications. Lastly, physicians should note that patients with IPSS≥16 would unlikely benefit from either intervention.
