Hello Sir, Since last few months I am suffering from kidney stones . After undergoing a KUB it was found that there were three stones in all one in the right kidney measuring 6 mm and two in the left kidney measuring 5 mm in size.After taking medication for last two months, I still feel slight pain in the urether area and got my second KUB done today. The latest report says the following there is dilatation of left pelvialyceal system and upper urether noted.Also there is echogenic shadow measuring 6 mm in middle calyx of right kidney.What does that mean? What is the position of the stone in my left kidney.

Hi, You must understand the Urinary Tract. Urine is filtered from the blood by two kidneys (right & left)which are located in the backside just below the last rib. Then it passes tho ureter to the Urinary Bladder - stored there till certain amount of collection & passed to the exterior tho Urethra (inside the penis / vulva). As long as stone is within the Kidney it may produce pain, but there will not be any blockade (acute & very severe pain). Problem starts once the stone descend via the ureter. If it descends and passes out there will be sudden onset acute pain sometimes vomiting also but relived after some time. Usually it gets blocked in the upper. Middle or lower part / end - at the junction To treat this problem urine should be made to secrete fast (forced diuresis) hoping the urine will flush away the stone. If it does not pass away & gets blocked anywhere in between consult a urologist & follow his advice. Sometimes blood investigation is needed to access what type of stone & treat accordingly Best Wishes
