Abstract
Botulinum toxin (BT) injections have been used successfully to treat spastic muscle conditions, including detrusor- sphincter dyssynergia (DSD) seen in spinal cord injury (SCI) patients. In our urology clinic, we used BT to treat three SCI patients who had voiding dysfunction, using a transperineal needle with electromyographic (EMG) monitoring. Two of the patients reported excellent results following the treatment. One patient, with whom the staff had difficulty doing intermittent catheterization (IC), improved significantly. The other patient had improved voiding with an external catheter and minimal urinary residual. The third patient had no improvement of leg spasms with his voiding dysfunction and required a sphincterotomy. Although patients may need repeat injections, BT is minimally invasive and easy to administer with no side effects. Overall, BT injection is an excellent method of managing voiding in SCI patients, especially those on continuous external catheters and with IC management who refuse or are not good candidates for surgery.
