Had pelvic u/s cos of high wbc in urine. person that did my u/s said everything looked ok but he will send result to my dr. should i still be worried?

Somewhat: The most common cause of a high urine white cell count is an infection of the bladder. This won't show on ultrasound, which is done to exclude other possible causes, some very serious. So if the u/s is negative, according to the tech who did it, that's good news, but you still have to find out why there are white blood cells in the urine and be treated for that--it isn't normal. Ask your doctor.
