If normal morphology for red cells can a renal cause be eliminated for a microscopic hematuria in urine?ct scan normal no infection.

See a Urologist: CT with contrast is good to find small renal masses. Really tiny ones not on CTs can still cause hematuria, but are often not clinically significant, at least not yet. A follow up CT sometime may be considered. Blood may be from the ureter or bladder,requiring CT/U/S or poss. MRI. Blood can come from diffuse renal disease, esp. if there is also protein in the urine. CT may not see this.
