| Description | Objective: Analysis of therapy by repeated intradetrusor application of botulinum toxin A in children’s urinary bladder detrusor overactivity. Material and methods: The study included a total of 17 patients between the ages of 6 and 14 years (mean 9.5, median 9). Eight of them were treated for neurogenic detrusor overactivity (Group I: 4 girls and 4 boys), and nine for non-neurogenic detrusor overactivity (Group II: 3 girls and 6 boys). Botulinum toxin A at a dose of 10 to 12 IU/ kg, in proportion to body weight, was applied endoscopically. Nine patients were treated twice, the others two or three times 6 months after previous injection in every case. Both urodynamic data and bladder diary data were assessed 1, 3, and 6 months after each application. Results: 11 patients (65%) showed improved urine continence while 2 (11%) of patients exhibited full extinction of incontinence. Extinction and/or reduction of non-inhibited detrusor contractions always culminated in the third month after application. No one child demonstrated a change of miction regime or need for catheterisation. Maximum increase of cystometric capacity took effect after 3 months: in Group I by 55% , in Group II by 40%. T he degree of greatest decrease of maximum detrusor pressure was: Group I by 49% three months after application; Group II by 64% , one month after second application. No adverse effects emerged during treatment. Conclusion: Intradetrusor application of botulinum toxin A appears to be a safe and efficient treatment for detrusor overactivity in children, regardless of its origin. Repeated application does not potentiate the effect of this treatment. |
