Had episode of gross hematuria. no infection. ct scan shows 2 non obstructing stones. could stones have caused the hematuria?

Yes: Kidney stones can cause bleeding usually associated with pain. If ct scan is negative for any other lesion, and stones not big enough to cause bleeding, have it checked for bleeding disorders. Bladder lesions need to be ruled out also.

Yes: Stones in the urinary tract is one of the causes of hematuria -either with or without pain.

Most likely: One of the most common causes of gross hematuria. Maintain good hydration, strain your urine, control pain. If stone excreted, make sure you take it to your doc for analysis.

Possible: Hematuria can certainly occur secondary to nephrolithiasis or "kidney stones". However, if you continue to have these episodes it is best to be evaluated by a urologist for consideration of further testing.

Hematuria: Hi, Most definitely a stone can cause blood in urine.

It possible but: You should probably review this with a urologist to make sure he/she feels this is truly the case. You may need to undergo urine cytology to assess for abnormal cells in your urine and even possibly cystoscopy, where your bladder will be evaluated for any concerning lesions.

Maybe: You still need a cystoscopy to evaluate the bladder lining.

Possible but: Are the2 stones in the kidney area or the ureter?What size?GROSS hematuria from small non obstructing stone would be quite unusual.In this context, cystoscopy to rule out bladder tumor and contrast CT-IVP with delayed films to rule out transitional cell tmr(the lining of the urinary tract)of a renal pelvis or ureter is a prudent diagnostic approach.The stones should be followed.Hope all turns well
