So apparently the operation was just sticking the catheter in plus pushing the crystals/stones back into his bladder. To take them out would be a whole nother surgery... : (
the doc said he could get blocked in a day or if were lucky, a few months. We are hoping it doesn't happen until atleast feb when my parents will get their tax money. So that's that. My mom is really upset about it.

Other than that I think he comes home tonight, I'll be sure to take pics.
