Predictive Urodynamic Parameters for The Treatment Efficacy of Onabotulinum A Toxin in Neurogenic Lower Urinary Tract Dysfunction
Predictive Urodynamic Parameters for The Treatment Efficacy of Onabotulinum A Toxin in Neurogenic Lower Urinary Tract Dysfunction
Purpose: To evaluate urodynamic parameters predicting the treatment efficacy of onabotulinumtoxin A (onaBoNT-A) in patients with neurogenic lower urinary tract dysfunction (NLUTD).
Methods: Patients with NLUTD who received 200 IU onaBont-A injections at Gaziantep University, Faculty of Medicine, Department of Urology between September 2013 and September 2023 were included in the study. Urodynamic parameters, including cystometric capacity, detrusor pressure (Pdet), and compliance, detrusor leak point pressure (DLPP), phasic or terminal neurogenic overactivity were assessed. Additionally, the correlations between these parameters and treatment outcomes were analyzed.
Changes in the number of pads used per day due to UI were assessed every 3 months during the postoperative period. The time lapsed to return to the pad usage levels before onaBoNT-A injections was recorded as the duration of the benefit.
Preoperative urodynamic data of the patients were compared between groups. Additionally, a subgroup analysis was conducted in patients who benefited from treatment to evaluate the correlation between treatment efficacy, duration of benefit from treatment, and urodynamic parameters.
