I have chronic kidney stones. ive had my gallbladder removed. i have severe right sided kidney pain on and off for over a month. no stone per kub, urine clear. goes away with hydration! what is wrong? my doctor thinks i'm crazy.

See a urologist: You could have a non opaque stone. There are several kinds of stones that do not show up on KUB. Most stones show on CT scan. A urologist should be able to help and to determine if there is a renal cause for your symptoms.

Stones not calcium: Not all kidney stones show up on xray. You should see a nephrologist or urologist to clarify the problem.

May be something els: If you are thinking kidney area, a KUB will not show everything. To fully evaluate your persistent severe pain, an abdominal CT scan with contrast may be warranted you are making the assumption your pain is kidney and it may not be. You could have unusual anatomy of the kidney system causing your problem or your pain may be a back problem but hydration would not help here. Get 2nd opinion .
