radiography of the urinary bladder using a contrast medium, used to diagnose tumors or defects in the bladder wall, vesicoureteral reflux, stones, or other pathological conditions of the bladder.


radiography of the ureters and renal pelvis.


radiography of the urinary tract after introduction of contrast medium.
