A urostomy involves replacing the bladder function by diverting your urine into a section of the small intestine.
During ostomy surgery, part of the small intestine (ileum) is isolated and brought out onto the surface of your abdomen creating an opening called a stoma.
Because the bladder has been removed there is no reservoir for the storage of urine. The isolated section of the small intestine has no muscle or valve to control urination, so you will need to wear a urostomy pouch to collect the urine.
