For a vcug test when i am done the test do i have to pee on the table because when my bladder is full its hard to move and i pee a little. ?

Here are...: Vcug is done to radiographically show if there is urine back-flow up to ureters/kidneys at voiding and / or any congenital blockage in the urethra, especially in prostate urethra. As to how peeing goes, the patient may not pee well simply from awkward lying position or indeed having blockage in urethra. So, doc involved should be able to explain either condition; ask and talk with doc. Best wish..
