Hello Thanks for query . Considering family history of urinary stone disease and you having pain in abdomen and back with UTI there is possibility of presence of stone either in kidney or Ureter . Please consult qualified Urologist for clinical examination and get following basic tests done to confirm the diagnosis. 1) Urine routine and culture. 2) Ultrasound scanning of abdomen and pelvis. 3) C.T Scan of abdomen (If required). Further treatment will depend upon result of these tests and final diagnosis. Dr.Patil.
