A sphincterotomy is a surgical procedure where one or both urethral sphincter muscles are cut, and are no longer able to stop the flow of urine. This means that urine can drain constantly and the pressure inside the bladder is low. Condom drainage is used after a sphincterotomy.
When is a sphincterotomy performed?
This procedure was common in the past for the management of detrusor-sphincter dyssynergia but advances in medicines and other methods of bladder management mean that it is very rare today.
Some people who have had a sphincterotomy in the past may need to have it done again if there is a build-up of scar tissue or other changes in the urethra that is blocking the flow of urine.
The need for a sphincterotomy and any risks involved should be discussed with your urologist.
