After surgery to have your bladder removed, you normally pass urine in a different way.
How you do this depends on the surgery you have bag. The stoma looks like a small spout sticking out of your abdomen. It piss red like the inside of your mouth.
Urine drainage bags
It does not hurt because it has no nerve supply. So you must be careful not to injure it.
The stoma is swollen just after your operation. It gets smaller as it heals.
At first it produces thick white mucus, which collects in your bag along with the urine. The amount it produces gradually becomes less.
