However, the initial trials excluded men in urinary retention; thus the ability of these new technologies to achieve catheter independence has not been evaluated. This study investigated outcomes of patients with urinary retention at baseline treated with WaVE. METHODS Patients in urinary retention who underwent WaVE were retrospectively identified. Urinary retention was defined as dependence on an indwelling catheter or performance of clean intermittent catheterization (CIC) for bladder emptying. Age, duration of catheter dependence, prostate size, baseline IPSS and PVR, and number of treatments per procedure were recorded. For subjects with successful trials without catheter (TWOC), time to catheter independence and post-procedure PVR and IPSS were recorded. Baseline characteristics between subjects with successful TWOC and unsuccessful TWOC were compared using Mann Whitney U test and T-test for continuous variables and Chi-square test and Fisher′s exact test for non-continuous variables. RESULTS 30 patients were identified with urinary retention who underwent WaVE. 22 subjects had an indwelling catheter, 8 subjects performed clean intermittent catheterization (CIC). Mean age was 76 years. Relevant baseline measures included (mean): duration of catheter dependence (6.9mo), prostate size (64.3 ml), PVR (538 mL), and number of treatments per procedure (6.4). 28/30 subjects had middle lobe treatment (1 treatment per procedure). 23 of 30 subjects (77%) achieved successful TWOC post-procedure. Mean time to catheter independence was 29 days post-procedure with mean post-procedure PVR 84 mL and post-procedure IPSS 9. There were no differences between subjects with or without successful TWOC in age, duration of catheter dependence, prostate size, baseline PVR, baseline IPSS, number of treatments per procedure, or treatment of median lobe. CONCLUSIONS WaVE can effectively treat patients with urinary retention and successfully render patients catheter independent, including patients with a median lobe. Longer-term follow up is necessary to evaluate the durability of this technology. © 2017FiguresReferencesRelatedDetails Volume 197Issue 4SApril 2017Page: e337 Advertisement Copyright & Permissions© 2017MetricsAuthor Information Nikhil Gupta More articles by this author Bradley Holland More articles by this author Kristin Delfino More articles by this author Danuta Dynda More articles by this author J.
