Which condition is characterized by the sac containing waste being surgically created?

The correct answer is characterized by a surgical procedure that creates an opening (ostomy) in the body for the purpose of expelling waste. An ostomy involves rerouting waste from its normal path in situations where the bladder or intestines may not function properly due to illness, injury, or congenital conditions. This procedure results in a stoma, which is an opening created in the abdominal wall through which waste can pass into a collection bag.

In comparison, hemodialysis is a treatment for kidney failure that filters waste and excess fluid from the blood using a machine, rather than creating an external collection point for waste. Diabetes is a metabolic disorder that affects blood sugar levels, while incontinence refers to the involuntary loss of urine or feces but doesn't entail a surgical procedure to manage waste.
