Final answer:
A continent ileostomy is a selected alternative to a conventional ileostomy that requires daily catheterization to evacuate the contents. It allows the patient to control when to empty the waste pouch using a catheter.
Step-by-step explanation:
The selected alternative to a conventional ileostomy that requires catheterization of the stoma daily to evacuate the contents is a continent ileostomy. In a continent ileostomy, a pouch is created from the small intestine and connected to the stoma, allowing the collection and control of waste material. With this alternative, the patient can control when to empty the pouch using a catheter, eliminating the need for an external bag.
