BOLANOS, Andrea et al. Experience with Botulinum Toxin in Children with Neurogenic Overactive Bladder: A Case Series. Urol. Colomb. [online]. 2022, vol.31, n.4, pp.149-154. Epub 05-Jun-2024. ISSN 2027-0119. https://doi.org/10.1055/s-0042-1758464.
Objective:
To describe the experience with the administration of botulinum toxin injection in children with neurogenic overactive bladder who were refractory to the first-line management.
Materials and Methods:
A descriptive observational study (case series) which included 14 children with a diagnosis of neurogenic overactive bladder who were refractory to the first-line treatment and were aubmitted to the intravesical administration of botulinum toxin between 2015 and 2021. Follow-up was performed taking into account the clinical variables, with an evaluation of the response and the adverse events. Absolute frequencies and percentages were reported for the qualitative variables; for the quantitative variables, measures of central tendency and dispersion were reported.
Results:
We included 6 boys and 8 girls with a mean age of 10.1 (standard deviation [SD]: ±4.4) years. All patients were previously treated with anticholinergics and clean intermittent catheterizations, with a mean use of 2.8 (SD: ± 1.0) diapers per day; 11 (78.5%) had a history of urinary tract infection, 13 (92.8%), constipation, and 2 (15.3%), fecal incontinence. On ultrasound, 7 (50.0%) patients presented bladder wall thickening, and 6 (42.8%), hydronephrosis. After the procedure, 1 patient presented urinary tract infection as a complication, 6 presented complete response, 7, partial response, and 1 patient did not obtain a response with the first injection, with an effective mean time of therapy of 8 (SD: ± 6.3) months. A second injection was required by 6 (42.8%) patients, and of these, 3 (50%) required a third injection.
Conclusion:
Intravesical botulinum toxin injection as a second-line management therapy for neurogenic overactive bladder yileds good results, with low rates of complications.
