Abstract

A case of milk of calcium renal stone seen in a hydronephrotic kidney was reported. The patient, 43-year-old man, was admitted to our clinic with the complaint of general fatigue and bloody stool. The plain film of abdomen revealed a left ureteral stone, and five round calcified shadows at the lower pole of the left kidney in supine position, which showed peculiar radioopacity of half-moon shape in upright or lateral position. The IVP demonstrated the left hydronephrotic kidney. Left ureterolithotomy and partial nephrectomy were performed 10 days after hospitalization. Chemical analysis of sand granules showed calcium phosphate and calcium oxalate. The literatures on this unusual condition were reviewed and discussed.
