The transmission of ultrasonic waves through the renal parenchyma allows visualization of the renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes.Computed tomography uses external radiation,and sometimes contrast media are used.Intravenous pyelography uses contrast medium and external radiation for radiography.Contrast medium is injected into the bladder through the urethral opening.External radiation for radiography is used before,during,and after voiding in voiding cystourethrography.
