Intradetrusor injections of onabotulinum toxin A (Botox®) 300 U or 200 U versus abobotulinum toxin A (Dysport®) 750 U in the management of neurogenic detrusor overactivity: A case control study.

AIMS - To compare the outcomes of the first intradetrusor injections of abobotulinum toxin 750 U and onabotulinum toxin 200 and 300 U in patients with neurogenic detrusor overactivity (NDO).

METHODS - A retrospective case-control study was conducted including 211 NDO patients treated in three consecutives eras with onabotulinum toxin 300 U (2004-2006; 80 patients), abobotulinum toxin 750 U (2007-2011; 78 patients) or onabotulinum toxin 200 U (2011-2014; 53 patients).

Urodynamic and clinical parameters were compared between groups. The primary endpoint was the rates of success defined as the combination of urgency, urinary incontinence, and detrusor overactivity resolution.

RESULTS - When comparing abobotulinum toxin to onabotulinum toxin any doses (200 or 300 U; n = 133), success rates were similar (65.4% vs. 55.6%; P = 0.16). Patients treated with abobotulinum toxin 750 U had higher success rate (65.4% vs. 41.5%; P = 0.007) compared to those who received onabotulinum toxin 200 U. In contrast, there were similar success rates in abobotulinum toxin 750 U and onabotulinum toxin 300 U groups (65.4% vs. 65%; P = 0.91) but with a trend towards longer interval between the first and the second injection in the onabotulinum toxin 300 U group (12.4 vs. 9.3 months; P = 0.09).

CONCLUSIONS - Intradetrusor injections of abobotulinum toxin 750 U for NDO provided better outcomes than injections of onabotulinum toxin 200 U. Success rates of abobotulinum toxin 750 U and onabotulinum toxin 300 U were similar but interval between injections tended to be longer with onabotulinum toxin 300 U. Neurourol.
