Does the setting for intradetrusor onabotulinumtoxinA injection for management of overactive bladder matter?

Intradetrusor onabotulinumtoxinA (Botox) injections, to treat idiopathic overactive bladder (OAB), can be performed in the office setting under local analgesia alone or in the operating room (OR) under local and/or sedation. The objective of this study was to compare the symptomatic improvement in patients with OAB who underwent treatment with intradetrusor onabotulinumtoxinA injections in an in-office versus the OR setting.

We performed a multicenter retrospective cohort study of women with the diagnosis of refractory non-neurogenic OAB who elected to undergo treatment with intradetrusor onabotulinumtoxinA injections between January 2015 and December 2020. The electronic medical records were queried for all the demographic and peri-procedural data, including the report of subjective improvement post procedure. Patients were categorized as either "in-office" versus "OR" based on the setting in which they underwent their procedure.

Five hundred and thirty-nine patients met the inclusion criteria: 297 (55%) in the in-office group and 242 (45%) in the OR group. A total of 30 (5.6%) patients reported retention after their procedure and it was more common in the in-office group (8.1%) versus the OR group (2.5%), (P = 0.003). The rate of urinary tract infection within 6 months of the procedure was higher in the OR group (26.0% vs. 16.8%, P = 0.009). The overall subjective improvement rate was 77% (95% confidence interval: 73%-80%). Patients in the OR group had a higher reported improvement as compared to the in-office group (81.4% vs. 73.3%, P = 0.03).

In this cohort study of patients with OAB undergoing intradetrusor onabotulinumtoxinA injections, post procedural subjective improvement was high regardless of the setting in which the procedure was performed.
