Abstract
- Ultrasonic definition of the kidney does not depend on renal function. Thus ultrasonography is capable of rapidly imaging functionally impaired kidneys not visualized during IVP or radionuclide renal scan. Ultrasonography was done on 67 patients with non-visualizing kidney. The causes of non-visualizing kidney on IVP were renal failure (39 patients), unilateral hydronephrosis (21 patients), small contracted kidney (2 patients), perirenal hematoma (1 patient) renal vein thrombosis (1 patient), hypoplastic kidney (1 patient) , renal agenesis (1 patient), and ectopic kidney (1 patient) In the most instances non-visualizing kidney had a characteristic ultrasonic pattern Ultrasonography was felt to be a valuable technique in the investigation of patients with non-visualizing kidney on IVP.
