There has been a rapid expansion of the armamentarium for managing benign prostatic hyperplasia (BPH). Given the invasiveness and complication risks of traditional surgical management, minimally invasive procedures have emerged. Rezūm water vapour therapy is a safe, effective alternative. Given the minimally invasive nature, there is interest in administering conscious sedation over general anesthesia (GA) to decrease procedural times and costs and increase accessibility by completing procedures in an office-based setting. We sought to assess and describe patient-reported tolerability for Rezūm completed under oral and deep intravenous sedation.
Patients who underwent Rezūm between April and November of 2022 under conscious sedation with oral sedation and local anesthesia (OSLA) or deep intravenous sedation (DIS) were enrolled. Baseline information was collected, and followup interviews were conducted where patient tolerability scores, future anesthetic preferences, and complication data was prospectively obtained.
Fourteen patients were enrolled in each group. The OSLA and DIS cohorts had a median tolerability score of 8 (interquartile range [IQR] 3.5) and 9 (IQR=1.75), respectively, indicating highly tolerable experiences. There was no significant difference between groups (p=0.13). On followup, 85.7% of patients in the OSLA and 100% in DIS groups expressed their future preference for conscious sedation over GA, with no significant difference between the two groups (p=0.46).
Our study demonstrates OSLA and DIS are both viable conscious sedation methods for Rezūm, with patients reporting high tolerability to the procedure regardless of sedation choice. Almost all patients receiving conscious sedation would choose to undergo Rezūm using conscious sedation again and had minimal complications.
