Description of intervention(s) / exposure
Patients with neurogenic detrusor overactivity (NDO) associated incontinence refractory to oral pharmacotherapy who received bladder BonT/A injections were recruited. The participants would receive BonT/A treatment regardless of their involvement in this study, as a third line treatment for refractory NDO. As per routine protocol approved by the Hospital Scientific Board all patients were submitted to urodynamic investigation at baseline, 4-6 weeks and 6 months post BoNT/A treatment. Urine specimens were obtained at baseline during the cystoscopy for the BoNT/A treatment, and upon routine urodynamic follow-up visits at 4-6 weeks and at 6 months post treatment.
Intervention code [1] 329512 0
Diagnosis / Prognosis
Comparator / control treatment
Healthy controls, without overactive bladder syndrome and that haven't received any treatment for overactive bladder syndrome in the past, that provided urine samples in similar time intervals - initial sample, in 4-6 weeks and in 6 months.
Control group
Active
