Hyperphosphatemia.: Calcium binds with dietary phosphate causing it to be excreted in the stool. This prevents hyperphosphatemia which is an important concern in advanced renal failure.
Dr. Ralph Morgan Lewis

AGN: Calcium & phosphorus r important for healthy bones, muscles, and nerves; however, in renal disease phosphorus may accumulate leading to unwanted consequences (including lowered calcium); thus calcium supplements (citrate/ carbonate/et al) r given to bind excess phosphate for excretion.
