How can I maximize the odds of a KUB X-ray seeing my kidney stone? Do I drink lots of water? Fast? Avoid foods that lead to gas?

I have a kidney stone in my upper ureter (verified by CT scan). It did not show up on a KUB X-ray. I'm going for a followup KUB X-ray in a few weeks. I would like to maxmize the chances that the stone will show up in the KUB so that I do not have to follow up with a CT.
Now, I know the stone may be transparent to X-rays (radiolucent). What I'm trying to minimize is that my bowels will obstruct the X-ray and hide the stone. I've read that stools and gas can block the stone from view. Should I do anything about this? Are there other things that can occlude the X-Ray that I should know about?
I know that you are not my doctor, etc. However, if you have advice on how to maximize the odds that a stone will show up, fire away. Bonus points if you can point me to a radiology text or similar that explains what a patient should do to prep for the exam.
In case it makes a difference, based on the CT the stone is approx 4.5mm. As far as I know no assessment has been performed for the kind of stone.
PS. I want to maximize the odds of the KUB finding the bugger because it will increase the odds that my doc will be able to use the external shock-wave thing to fragment it, assuming it's moved a bit lower in my ureter, and also it will let me avoid the higher dose of radiation I'd get from a CT.
PPS. I know you are not my doc. I would ask my doc, but he's got poor communication skills and so I'd rather find pointers to authoritative material, or advice that will lead me there.
