OBJECTIVE: This study aimed to evaluate the efficacy of treatment for incontinence due to neurogenic detrusor overactivity (NDO) and idiopathic detrusor overactivity (IDO) with onabotulinumtoxinA (BoNT-A) at Aarhus University Hospital, Skejby, Denmark. MATERIALS AND METHODS: The data were collected retrospectively by systematic review of the patient records from March 2003 to May 2012. Patients treated with BoNT-A over the age of 18 years were included. Treatment indication, diagnosis, adverse events, treatment interval, duration of effect and effect grade were registered. Follow-up data were collected by a telephone interview 4 weeks after treatment. RESULTS: The study identified 219 patients, who received a total of 657 treatments during the period. Full effect of the treatment was experienced in 71%, intermediate effect was seen in 16% and low effect in 3%. There was no difference in effect duration between the IDO and NDO groups. The most common adverse event was the need to perform clean intermittent self-catheterization; 27% of all patients experienced this. Urinary tract infections were reported in 5% of procedures and significant haematuria in 1%. These findings correspond with the results of other published studies. CONCLUSION: BoNT-A is a safe and effective treatment for incontinence in IDO and NDO.
