Abstract
INTRODUCTION AND HYPOTHESIS
Intradetrusor onabotulinumtoxinA (BTX-A) is a third-line therapy for overactive bladder (OAB), however several gaps exist in periprocedural care. Prior studies have demonstrated BTX-A efficacy at 2-3 weeks, but there are limited data documenting when patients should begin to note symptom improvement. The primary aim of this study was to evaluate patient-reported temporal improvement in symptoms, with secondary aim to evaluate medication resumption rates, following initial BTX-A injection.
METHODS
A prospective, single-arm cohort study of patients with non-neurogenic urgency incontinence undergoing initial BTX-A injection was performed. Intradetrusor 100 units BTX-A was administered in standard 20-site template. Patients discontinued OAB medication(s) at BTX-A injection and completed a daily Patient Global Impression of Improvement (PGI-I) diary for 3 weeks. Data were collected at 1 month, including final satisfaction score, medication resumption rates, and adverse outcomes.
RESULTS
Fifty-one patients were included, with 25 patients (49%) actively taking an OAB medication. Median time to first improvement was 3 days, at least "much better" (PGI-I <2) was 5 days, and maximal improvement was 7 days. Twenty of 25 patients (80%) opted to remain off OAB medications at 1 month based on symptomatic improvement following injection. Adverse outcomes included urinary tract infection in three patients (6%) and symptomatic incomplete emptying requiring temporary intermittent catheterization in two patients (4%).
CONCLUSIONS
Median time to first and maximal improvement was 3 and 7 days, respectively, following initial 100 units BTX-A. Eighty percent of patients on medications opted to remain off at 1 month. These data may help further counsel patient expectations following initial BTX-A therapy.
