Long-term follow-up of intravesical abobotulinumtoxinA (Dysport®) injections in women with idiopathic detrusor overactivity.
Asian Journal of Urology 2024 January
OBJECTIVE: Only a few numbers of studies have been published on the use of abobotulinumtoxinA (Dysport®) in idiopathic detrusor overactivity (IDO). This study reported the long-term follow-up of women with IDO who were treated with intravesical Dysport® injections.
METHODS: Two hundred and thirty-six patients with IDO who had failed first-line conservative and antimuscarinic therapy received 500-900 units of Dysport® between April 2014 and July 2015. All patients were followed up for 5 years after their initial injection and interviewed on the phone.
RESULTS: A total of 236 women with IDO aged from 18 years to 84 years (mean±standard deviation: 49.6±15.9 years) were included in our study. The median follow-up time for patients was 36.5 (range: 10-70) months, and the median recovery time after injection was 18.5 (range: 0-70) months. A total of 83 (35.2%) patients stated that they had subjective improvement of their symptoms whereas 84 (35.6%) patients did not report any improvement in symptoms. The initial International Consultation on Incontinence Questionnaire Overactive Bladder mean score was 6.9 (standard deviation 3.4). There was a positive association between the median recovery time and the components of the International Consultation on Incontinence Questionnaire Overactive Bladder questionnaire.
CONCLUSION: In a sub-population of overactive bladder patients with IDO who have failed first-line therapy, a single intravesical Dysport® injection can resolve patient symptoms completely or reduce the symptoms to an acceptable level that can be controlled with antimuscarinics or re-injection on demands.
