Hi Richard, my husband had TURBT to remove 2.5cm tumor from his bladder in Aug 2021.

The surgery itself was not long (less than a hour), they flushed his bladder with the same chemo drug as you mentioned right after. You will stay in the post-op area for about 2 hours, after then the nurse will get the chemo fluid out through a catheter, you will be asked to sit on the toilet to pee at home for the first 8 hours and add bleach to the toilet bowl, soak it for a while before flushing. You should be drinking lots of water during the first 8 hours after you are discharged.

You will have burning sensation for about two days or less. They might give you some medication for that which makes your urine orange.
It is stressful waiting for the biopsy result, which determines whether the tumor is benign or malignant, and if malignant, it will tell you the grade and stage. We have been through all these, if you have questions, please feel free to reach out.
Wishing you the best of luck on Tuesday!

Jas
