Purpose:
This study investigated the relationship between the subjective outcome assessment and objective parameters after intravesical onabotulinumtoxinA injection in patients with overactive bladder.
Materials and Methods:
A total of 77 patients with urodynamically confirmed detrusor overactivity were treated with intravesical injection of 100 U of onabotulinumtoxinA in 20 divided injections (5 U in 0.5 ml normal saline each) at different sites sparing the trigone. The primary end-point was the change in the Global Response Assessment (GRA) 3 months after treatment. All patients were monitored monthly after treatment for up to 6 months. Patients were divided into the successful and failed treatment groups according to the change in their GRA (≥ 2 and ≤ 1, respectively) 3 months after injection. The changes in voiding diary variables, Urgency Severity Score (USS), Overactive Bladder Symptom Score (OABSS), maximal bladder capacity (MBC), post-void residual (PVR) volume, and voiding efficiency (VE) were compared between groups at each time point
Results:
Overall, the USS and OABSS and MBC improved after treatment. Three months after BoNT-A injection, 49 (64%) patients reported an improvement in the GRA of 2 (n = 30) or 3 (n = 19). Six months after treatment only USS, OABSS, and urgency episodes showed significant difference between the groups. No significant difference in MBC, PVR or VE was noted between groups at 6 months.
Conclusion:
Subjective, successful treatment outcomes of intravesical onabotulinumtoxinA injection for treatment of overactive bladder were significantly associated with a reduction in USS and decreased urgency and urge urinary incontinence episodes.
