The behaviour of the ureters following radiotherapy and Wertheim hysterectomy.

The pyelographic appearances following Wertheim hysterectomy have been studied in 19 cases. The dilatation of the lumbar segments with unusually rapid transmission through the pelvic segments has been found 6 weeks postoperatively although this dilatation has disappeared in most cases by 6 months. Late ureteric dilatation is of no value in itself in determining the presence or absence of recurrent growth.
