About a year and a half ago my routine physical uncovered blood in my urine. It was described as microscopic hematuria. A second urinalysis confirmed this finding.

I went to a urologist who ordered performed a cystoscopy which came back negative. Urine cytology came back negative. He ordered up an ivp which showed a 2mm filling defect in one kidney in the calyx.

I then had a non-contrast ct scan that showed nothing in the area of the filling defect.

To split the difference, the doc performed a retrograde pyelogram, scoped the kidney, and did washings. With the scope he could see nothing in the area of the filling defect, the pyelogram showed nothing, and the washings yielded no abnormal cells.

Six months later, we did another ivp and the filling defect persisted. Now, about 6 months after that, another ivp shows the same filling defect.

Since this all began, I have had a number of urinalyses that have yielded varying results. Some show a few more rbcs than they'd like to see. A couple of others have been totally clear. Yet others had no rbcs, but only "chemical blood."

don't get me wrong, I trust my doc completely. In talking with a gp I know, he said that there may be no connection between the filling defect and the hematuria and that the blood could be from something as simple as a leaky capillary anywhere in the urinary tract.

I guess my question is, am I too anxious for closure on this?
