Hi, I am a 44 yr. old female (4'11, 135 lbs.). I have a history of hysterectomy (2003), gastric bypass (2012) and adrenal insufficiency (2012), for which I take hydrocortisone daily. Recently there has been visible blood in my urine and my urine analysis came back positive with a large amount of blood, protein (30), bilirubin (small), ca oxalate crystals (many), rbc (17), wbc (<50), hyaline casts (1) and leukocyte ester (small). I have an appointment with a urologist pending but am curious to find out what this could be. Should I be concerned? Please advise.
