[|Human|] i m 23 yrs male... i have a calculus (4mm) in the mid pole of right kidney and a concretion in lower pole of left kidney... last year in (august 2011 ) i have a stone in pelvis (11mm) which was removed via operation... Now again a stone... what is the reason behind the stone formed in such a quick time...
[|AI|]  Hi, Looks like you need a metabolic evaluation for urinary stone disease. This includes a blood chemistry with calcium, creatinine, phosphorus, uric acid, urea, and a complete urine examination. Serum PTH might be needed if calcium is higher. Occasionally we do recommend 24 hour urine tests for these salts and also citrate and oxalate. Following this We will be in a position to recommend precautionary measures. Regards.
