Botox bladder injection is used 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 wall of the bladder to paralyze the bladder muscle. The effect is 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 lasts only up to 9 months. Repeat injections are then needed.

Complications include:

  • bloody urine. This should clear up in a few days.
  • retention of urine. This may require temporary self-catheterisation for up to 1month.
