Hi, Ultrasonogram and X-ray KUB are the basic tests which are done to detect kidney stones. A computed tomography (CT scan) with urography (injection of contrast to visualize the structure of urinary tract and functioning of kidneys) is required if there is any doubt about the presence of stones (especially ureteric stones), anatomy of urinary tract or when a surgery is planned. Some of the routine tests include: serum creatinine to assess kidney function, serum calcium to look for increased calcium levels, urine pH to rule out abnormal pH causing precipitation of salts and urine WBCs to look for associated infection. What was the size of your right kidney stone? Was it single or multiple? What was the location inside kidney - pelvis or calyx? These factors decide on the further management. I will be able to guide you better with more information. Please mention your age, sex, associated medical conditions, drug intake and past surgeries when you get back. Wish you good health, Dr. Raguram.
