Water vapor thermal therapy for indwelling urinary catheter removal in frail patients.

PURPOSE: To report the efficacy and safety of water vapor thermal therapy to achieve catheter removal in frail patients with refractory acute urinary retention. METHODS: Data from consecutive frail patients with indwelling urinary catheter undergoing the Rezum™ therapy (Boston Scientific Corporation, Marlborough, MA) at a single center between October 2017 and June 2021 were prospectively collected. The included patients were deemed unfit or at high risk of complications for conventional benign prostatic hyperplasia (BPH) surgery. Prostate volumes up to 120 mL were considered eligible. The primary endpoint was successful cessation of catheter dependency, assessed postoperatively and up to 1 year of follow-up. RESULTS: A total of 24 men met our inclusion criteria. The median age, Charlson comorbidity index, and duration of preoperative catheterization were 77 years (IQR 67-86), 6 (IQR 3-7), and 113 days (IQR 87-159), respectively. Two cases (8.3%) of postoperative complications were recorded (Clavien II and Clavien IIIa). After a median postoperative catheterization time of 21 days (IQR 11-32), all patients regained spontaneous voiding. During follow-up, two patients died and a total of 22 patients completed the 1 year follow-up. All patients maintained spontaneous voiding without recurrence of urinary retention. No surgical retreatment was performed. In terms of pharmacological management, 22/24 patients (91.7%) had a BPH medication pre-Rezum™; this decreased to 8/22 patients (36.3%) post-Rezum™ (p < 0.001). CONCLUSIONS: In this single-institution, prospective, and observational study, water vapor thermal therapy was found to be effective and safe in restoring successful spontaneous voiding in a cohort of elderly and frail patients.

Head-to-head comparison of prostatic urethral lift and water vapor thermal therapy for the treatment of symptomatic benign prostatic hyperplasia: a real-life study.

PURPOSE: This study aimed at reporting a head-to-head comparison between water vapor thermal therapy using the Rezum™ system and prostatic urethral lift using the Urolift™ system in men with lower urinary tract symptoms due to benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: From December 2017 to November 2019, consecutive patients who underwent Rezum™ and Urolift™ procedures in two urology centers have been retrospectively considered. Only patients with a prostate size less than 80 mL were included. We used the PSM method to adjust baseline differences between both groups. The co-primary endpoint included the change in International Prostate Symptom Score (IPSS) and IPSS- quality of life (QoL) from baseline to 12 months. RESULTS: A total of 61 (52.1%) and 56 (47.9%) patients underwent Rezum™ and Urolift™ procedures, respectively. After PSM adjustment, 24 patients were included in both groups. No serious adverse events occurred (> Clavien II) in both groups. At 12 months, higher IPSS improvement was observed in the Rezum™ group (median:4 [IQR 3-5]) than in the Urolift™ group (median:8 [IQR 7-12]), without statistical difference (p = 0.08). The improvement in term of QoL at 12 m was similar (p = 0.43). The retreatment rates were 25% (Urolift™) and 8.3% (Rezum™), p = 0.24. Erection and ejaculatory function scores did not change significantly in either treatment group. Results in the full cohort showed that Rezum™ appeared to deliver greater improvements for IPSS and IPSS-QoL (p < 0.001 and p = 0.006, respectively) and lower reintervention rate (p = 0.006) than Urolift™. CONCLUSIONS: In this small retrospective study, our results indicate that both Rezum™ and Urolift™ provide a clinically significant improvement in symptoms and QoL, although some of these improvements were greater in the Rezum™ arm. Future studies are needed to definitively assess which treatment would be best suited for each patient.
