You are working in a busy urology clinic and see a patient who was just sent up from the ER. He is complaining of pain in his back from which he cannot find relief. He was diagnosed with a stone before by finding it in his urine. An abdominal X ray without contrast shows no evidence of a stone, but he does have blood in his urine. His stone is likely made of which of the following? A. Ammonium, magnesium, and phosphate B. Calcium C. Cystine D. Phosphate E. Uric acid
