1 occasion of gross hematuria, no symptoms, urinalysis came back negative. Age 23. Should I push for further investigation? What could be cause?

If you have continued to take aleve (naproxen) or another pain medication, you could have bleeding from your kidney from that. Sometimes a clot in the ureter tube could cause pain and hydronephrosis as well. ...Read more

This is called angiodyspasia, not uncommon. Cystoscopy will look for bladder source of bleeding. ...Read more

If a child presents with end-of-stream (terminal) gross hematuria, what is the standard workup after an xray shows no stones and urine culture normal?

Here's my thought...: How old is the child? Did he have any change in his usual voiding pattern?
