Can a urine test show you have kidney stones?

Can a urine test show you have kidney stones?

No but suggests: Urine test in persons with kidney stones usually shows red blood cells under the microscope. However, if the stone is dormant and small it may show nothing.

My blood test showed higher level of protein. Was sent for urine test and showed protein in urine. I have had three kidney stones, but none currently.

Protein in urine: Requires follow up with quantification of amount - there are two ways to do this: cup of urine with protein to creatinine ratio mg/mg -- or a 24 hour urine collection. Both are meaningful. Blood tests need interpretation, also. High protein in blood could indicate an evolving disorder that requires characterization with electrophoresis. Urine protein should be characterized with electrophoresis. ...Read more

The most common: Adrenal mass seen in about 15% of patients is an adrenal adenoma which is a benign tumor. It is easy to characterize on MRI because we can show there is fat in the tumor. This usually (94% accurate) means that the adrenal tumor is benign. But we make sure by following the tumor with additional MRI studies, which do not use harmful radiation. Ultrasound is not as accurate for followup. ...Read more

I have been having left pain in my kidney area for the past 4 days. Can a urine test be normal and still have kidney stones?

I have been having left pain in my kidney area for the past 4 days. Can a urine test be normal and still have kidney stones?

It is possible: You may have stones that are moving within the kidney and causing episodic mild obstruction if they are located near the junction of the kidney and the kidney drainage tube (ureter). The key question is whether your pain occurs with changes in position (twisting upper body, bending or standing from a sitting position). If this is the case, the pain may be back related (musculoskeletal). ...Read more

I was tested for kidney stone. Dr. Said nothing came up in urine test. Is that defiinte?

I was tested for kidney stone. Dr. Said nothing came up in urine test. Is that defiinte?

Not at all..: Acute kidney stone as it is passing down can cause some bleeding, thus urine testing for presence of blood and not stone. Many diseases cause blood in urine--bladder or kidney infection, tumors etc...So blood in urine does not necessarily mean stone. A spiral ct is an excellent test these days and can help detect where and how big the stone is. Consult your doc. Good luck. ...Read more

I had kidney stones is past, now in my urine test hows hyaline cast 0-5* , what is that?

Likely normal : Hyaline cases are the most common casts seen in the urine and when found alone, usually mean normal and only indicate that the patient may have had somewhat concentrated (e.g. Not drinking enough water) urine at the time it was collected. ...Read more
