Calcium phosphate renal calculi

Calcium phosphate renal calculi are mineralized crystalline concretions that form within the renal collecting system and urinary tract

They represent a distinct subtype of nephrolithiasis characterized by the precipitation of calcium and phosphate ions, predominantly as hydroxyapatite or brushite, driven by urinary supersaturation in an alkaline urine environment

This condition commonly arises in patients with systemic or metabolic derangements, most notably distal renal tubular acidosis, primary hyperparathyroidism, or hypercalciuria

Clinically, these calculi can cause flank pain, renal colic, hematuria, and urinary tract obstruction, and they are notable for higher recurrence rates and greater resistance to certain forms of shock wave lithotripsy compared to calcium oxalate stones
