July 1 · Diagnosing kidney stones
The first signs
About six weeks ago my urine turned a dark brown in color. Very similar to some dark oak furniture in my house. I had no pain outside of typical lower-back muscle pain, which has been common for me for the last several years.
The discoloration stayed with me for a few days. Then it would clear up and return again in a short period of time. I decided I needed to be checked out by a doctor.
The doctor discovered through a simple urinalysis that the dark color of my urine was a result of blood. He ordered a KUB — kidney, ureter, bladder — X-ray. The X-ray was clear. There were no kidney stones. My urine cleared up.
Because I am a heart patient taking Coumadin, I attributed the blood in the urine as a by-product of the blood thinner.
