Under visual control through the cystoscope 300 units of BTX-A were injected into detrusor muscle at 30 sites, sparing the trigone. After the treatment patients continued to perform clean intermittent self-catheterization (CIC) and clinical follow-up was planned for 6 weeks, 6 months and 9 months after treatment and urodynamic study was repeated after 6 weeks.Results: At the 6-week follow-up complete continence was restored in  9 of the 12 patients and after 6 months of 9 continent patients 1 patient lost his follow-up  from the study and 7 were still continent. After 9 months 3 patients remained continent. Mean cystometric bladder capacity (p
