Calcium Metabolism....Good Day Doctors;My age is 30(Male) and I work at sea. Shortly I had a kidney stone problem. And the stone was also out through urine.The stone was around 4-5 mm, Which I had given to the doctor for verifying the stone composition. But during the X-Ray the doctors found that their are no more stones in the kidneys and the Urinary Track. But they advised that I have some extra calcium deposits on the Ribs and found that there is some calcium deposits on the pelvis bone to. They advised me that It could be a problem of Calcium Metabolism.    Previously also around 4 years back I had the same stone problem on the right hand kidney. But nothing was discovered during the X-Ray and Ultrasound.     For us we go through the annual medical examination every year, But nothing as such was told or discovered by the Doctors during the examination of full chest X-Ray before.     My intake for water was very low from previous time. I was taking 3 Boiled eggs everyday, Combined Daily intake of Green Peas or other pulses with rice. I was involved in doing some physical exercise too. I do not know the reason for this, It would be of great help if could advise something regarding this.

### output:

Ultrasound and X-rays are poor in diagnosing stones. I would advise you to undergo the following tests. CT scan of abdomen pre- and post-contrast, Blood tests-calcium, uric acid, creatinine, serum PTH, alkaline phosphatase, PSA, creatinine, urine for hence Jones protein and routine analysis as a minimum. You might need additional tests such as bone scan or myeloma screen depending on the exact findings on the X-ray. If you are a recurrent stone former then you might also need 24 hour urine collected and analyzed for calcium, uric acid, oxalate and citrate as a minimum. You might want to see a general physician or endocrinologist for evaluation.
