If a contrast medium is used,intravenous fluid may be given to promote excretion of the contrast medium.Contrast medium also may act as a diuretic,resulting in the need for fluid replacement.The client will not require bedrest.Although urinary output should be monitored closely,there is no need for an indwelling urinary catheter.There is no need to cancel the procedure as long as actions are taken to protect the kidneys.
