DEAR DR. ROACH: My question is about microscopic hematuria. I see a rheumatologist for sarcoidosis. In February 2018, I had various lab tests, including a urinalysis. That test and several since then have shown microscopic hematuria. The rheumatologist sent me to a urologist, who did scans and a scope of the bladder up through the right kidney. There's a slight stricture of the right ureter. My biopsies were negative.
Tests and scans continue to be OK except for the microscopic hematuria. I am a 60-year-old woman. Is the hematuria a cause for concern? -- K.E.
