Objective: To assess effective outcomes following repeated treatment with intradetrusor botulinum toxin type A in patients with neurogenic detrusor overactivity (NDO).

Methods: Patients with NDO secondary to spinal cord injury (SCI) were enrolled. Botulinum toxin type A 200 U detrusor injections by a rigid cystoscope were repeated. Primary outcomes were urodynamic variables including maximum detrusor pressure during first involuntary detrusor contraction (Pdetmax IDC) filling cystometry, detrusor compliance (DC). Secondary outcomes were improvement of the patient’s quality of life (QoL) measured by Incontinence-Specific Quality-of-Life Instrument (I-QoL), the validated short forms of Urogenital Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7). Related adverse events were recorded.

Results: From 2012 to 2014, 159 injections were performed in 52 patients (44 male, 8 female). The mean age was 36.67 years. The maximum number of repeated injections was five. BC increased from (4.03–7.45) to (6.96–10.86) mL/cmH2O, Pdetmax in bladder storage decreased from (42.80–79.52) to (26.40–43.33) cmH2O, respectively. The I-QoL, UDI-6 and IIQ-7 showed a consistent improvement after repeated injections.

Conclusions: Repeated intradetrusor botulinum toxin type A injections remain improve QoL in patients with NDO secondary to SCI.
