Went to er for severe lower right ab pain and back pain. dr said i had kidney stone and hematuria. did urine and blood tests only but no cat scan, why?

See answer: Though symptoms and u/a may be suggestive, one cannot reliably make the diagnosis of a kidney stone without some type of an imaging study (kub, ultrasound, ct) with a non-contrast ct scan being the most accurate and reliable imaging study to determine the presence, location, and size approximation of a stone as well as to potentially rule out other causes of pain and hematuria.
