Here is what Casie his mom put up on their Facebook page Sams' Fans...
Sam is having surgery tomorrow to remove the spot on his kidney. Surgery is scheduled for 9:30 and he will be admitted for 2-3 days after. Please pray for a smooth and uneventful surgery and recovery, and that the biopsy will come back totally, unequivocally, definitively clean.
1 Samuel 12:16 ESV
Now therefore stand still and see this great thing that the Lord will do before your eyes.
Thank you for your prayers!
