Hi, @spooz2. I appreciate Colleen's foresight in asking about your hematuria. I'm hoping you're OK about the diagnosis of an idiopathic condition. That's my situation also. My urologist gave me a long lecture on the wide range of possibilities: Any number of arteries, veins, or capillaries around my bladder might be the source of the blood -- tracking it (or them) down would be difficult. Besides, the blood was pretty dilute when it came out, suggesting a relatively minor source, and it ended in a day or two. If it were "frank" (undiluted) blood, we would have spent some time and money tracking it down. Now, 10 years later, I still get a little pink now and then, but don't worry much about it. My (now) annual cystoscope exam reassures me. Martin
