Will i need a catheter in after brain surgery?

It depends on the specific type of brain surgery you have and your individual medical needs. In some cases, a catheter may be necessary to help drain urine from your bladder. This is typically done if you are unable to urinate on your own after surgery or if your urine output needs to be closely monitored. The catheter is usually removed within a few days after surgery, once you are able to urinate on your own.
