Yes. I have botox done every 6-9 months to relax the bladder and sphincter muscles. I have detruser sphincter dyssynergia on top of neurogenic bladder. I have no feeling in my bladder that tells me when my bladder is full. With the dyssynergia my bladder doesn't contract fully to empty and at the same time the sphincter doesn't relax to allow passage.
I have the botox done to basically allow the urine to pass easily without building up. With this I don't have to cath at all. I do have to wear diapers though as I leak without control afterwards. This is purposeful for me though as I can't tolerate caths for multiple reasons.
