CAUTI prevention after removal

Hello,
My facility has a protocol that after a urinary catheter is removed, we wait 2 hours to see if the patient voids. If they don't void, we do a bladder scan and determine the need for straight cath depending on what the scan shows.
I would like to know if anyone else does this at their facility. Also, I can't find anything in the literature that would suggest this is best practice. The Joint Commission mainly focuses on insertion and maintenance. Can anyone help?
Thanks.
2 hours? We give them about 6 hours. However, we may chose to bladder scan however frequent and determine the need to cath whenever based on the physicians orders. But we definitely give the patient more than 2 hours!

4 to 6 hours here. However, if the pt is symptomatic and can't void, we obviously won't wait that long. 2 hours is not nearly long enough.

6-8 hours,

We give the pt 8 hours to void.

We do 4-6, and sometimes the 6 turns into 8. Then we bladder scan and if there is <400 in the bladder we give another 2 hours for them to try to void on their own. If there is >400 then we straight cath and that starts the whole clock over again.
