A 30 year old woman was recently diagnosed by her family physician with a urinary tract infection. The urinalysis at the time showed microscopic hematuria. At the following visit 3 months later, another urinalysis showed microscopic hematuria with no other abnormalities. Urinary protein excretion and blood pressures are normal. The patient is asymptomatic; she has never seen blood in her urine. She notes that several family members have positive tests for microscopic hematuria but no symptoms and no renal failure. Renal biopsy here is not indicated, but if you did a renal biopsy, you would see the following:
The top is normal; the bottom would be the patient's EM. Light microscopy is normal.
