Why phosphate rises in CKD but not calcium?

Hello, I have been looking everywhere to find the answer for this, because I don't want to take anything at face value.

Basically, calcium and phosphate are related. Their absorption is increased by vit D. They are also both eliminated by the kidneys in urine.

I am wondering why in CKD, hyperphosphatemia is an issue, but not hypercalcemia?

If kidney function goes down, that means both calcium and phosphate will suffer inn terms of elimination. Also, with reduced vit D activation, both calcium and phosphate will suffer in terms of absorption.

So why does literature only mention that phosphate is retained in CKD? I think it should be both hypercalcemia and hyperphosphatemia.
