The bladder, if normal on CT, could still have non-invasive cancer that does not distort the bladder wall. A cystoscopy where the urologist looks into the bladder with a scope via the urethra is needed to be sure. ...Read more

Work with one Doc.: It is important you see one physician when trying to find the cause of abdominal pain.
