Three methods of assessment of upper urinary tract dilatation were compared prospectively. Forty-eight dilated renal units (35 patients) were studied, the majority being idiopathic pelvic hydronephrosis (69%). Dynamic computed tomography (CT) involves rapid sequence CT after injection of contrast medium. The maximum enhancement of a medullary region of interest (MMR) and its rate of enhancement (SMS) were derived from dynamic CT. Dynamic CT was compared with diuresis probe renography and… CONTINUE READING
