He was called  right away by his phycisian to book him for an appointment . Can it  be serious???
[|AI|]  Hello, Thanks for the query to Chat Doctor. Forum. There are two stones in left kidney, low grade fever, chills, cyst, backache. May be, 1 Kidney disease as due to stones in the kidney, usually there develop shy Chat Doctor.  Diagnosis can be confirmed by C T scan (as already done).2 Due to cyst or stone kidney got infection and developed glomerulonephritis or pyelonephritis (depending upon the location of cyst or stone). In my opinion get in serum creatinine level to evaluate the diagnosis and kidney damage. Good luck.
