Botox Bladder Injections
Botox can be injected into the bladder muscle to treat refractory cases of overactive bladder or urge incontinence that do not respond to medication. A total of 100U to 200U of Botulinum toxin A is injected into the inner wall of the bladder to paralyze the muscle. The effect can be seen as early as 2 weeks after injection. The procedure is done under general anesthesia as a day case and takes less than 15 minutes to do. Success rates are around 70 to 80% but the effect is temporary and usually lasts 6 to 9 months. Repeat injections may then be needed.
- bloody urine. This lasts a few days
- retention of urine. This may require temporary self-catheterisation for up to 1month.
