RESUMO
PURPOSE: To report our preliminary experience with water vapor thermal therapy with the Rezum™ System and Prostate Artery Embolization (PAE) for treatment of medically refractory, complete urinary retention to achieve successful cessation of catheter dependency in frail-patients. PATIENTS AND METHODS: A multi-institutional study was conducted including all patients who underwent Rezum™ procedure and PAE between October 2017 and June 2020. The included population focused on frail-patients unsuitable for conventional surgery with complete urinary retention. Rezum™ patients were identified and matched (1:1) with patients who underwent PAE. The matching criteria were age, Charlson score, prostate volume and duration of follow-up. The primary outcome was catheter-free survival, defined as spontaneous voiding and release from catheter dependence. RESULTS: Eleven patients from the Rezum™ group were matched to 11 embolized patients. PAE and Rezum™ patients were comparable in age (median: 77 vs. 75 years), Charlson score (median: 6 vs. 6) and prostate volume (74 vs. 60 cc). Procedures were significantly longer in the PAE group compared to the Rezum™ procedures (median: 148 vs. 8min, P<0.001). After a median follow-up of 12 months, spontaneous voiding was conserved in all cases (100%) after the Rezum™ procedure and in 5 cases (45.4%) after PAE (P=0.01). In catheter-free patients, the rate of benign prostatic hyperplasia medication use after procedure was 40% for PAE and 18.2% for Rezum™ patients (P=0.54). CONCLUSIONS: Our preliminary experience for treatment of complete urinary retention in frail-patients shows the feasibility of PAE and Rezum™ to restore spontaneous urination without being associated with the occurrence of major complications. Early data suggests that Rezum™ may provide superior results in terms of cessation of catheter dependence. Future studies are needed to definitively assess which treatment would be best suited for each patient. LEVEL OF EVIDENCE: 3.

Purpose: To evaluate the efficacy and safety of benign prostatic obstruction (BPO) surgery in patients with preoperative urinary catheterization. Patients and Methods: We conducted a multi-institutional retrospective study including all patients who failed a trial without catheter (TWOC) after acute urinary retention (AUR) between January 2017 and January 2019. Patients with neurogenic bladder, prostate cancer, or urethral stricture were excluded from the analysis. Patients underwent either monopolar/bipolar transurethral resection of the prostate (TURP), photoselective vaporization of the prostate (PVP), prostate artery embolization (PAE), open prostatectomy (OP), or endoscopic enucleation. The primary endpoint was 12-month urinary catheter-free survival without using benign prostatic hyperplasia medications. Results: One hundred seventy-one consecutive men (median age: 71 years; median prostate volume: 75 cm3) underwent BPO surgery, including 48 (28%) TURP, 62 (36.3%) PVP, 21 (12.3%) endoscopic enucleation, 15 (8.8%) PAE, and 25 (14.6%) OP. The median duration of preoperative urinary catheterization was 69 days (interquartile range 46-125). The 12-month urinary catheter-free survival rate was 84.8% (145/171). Satisfactory voiding returned to 121 patients (70.8%). On backward stepwise multivariable analysis, PVP (odds ratio [OR] 0.27 [0.10-0.69]; p = 0.008), PAE (OR 5.27 [1.28-27.75]; p = 0.03), endoscopic enucleation (OR 0.08 [0-0.49]; p = 0.023), OP (OR 0.10 [0.01-0.57]; p = 0.034), Charlson score (OR 1.36 [1.14-1.66]; p = 0.001), and number of preoperative TWOC failure (OR 2.53 [1.23-5.51]; p = 0.014) were significantly associated with catheter-free survival. Conclusions: In this multi-institutional retrospective study, including patients with preoperative catheterization, the overall success rate of BPO surgery was 70.8% after 1-year follow-up. Compared with TURP, enucleation methods and PVP were associated with better catheter-free survival, whereas PAE was associated with higher risk of AUR recurrence.
