Excretory urography has been routinely included in the staging work-up of uterine cervical carcinoma in the era of popular use of computerized tomography(CT). The purpose of this retrospective study was to evaluate the necessity of excretory urography in the staging of uterine cervical carcinoma in addition to the routine CT. In 143 patients with histologically proven uterine cervical carcinoma we compared excr-etory urography with CT in respect to the ability of each study to demonstrate the pelvocaly-ces and the ureters the level and the cause of the ureteral obstruction and the invasion of urinary bladder. The results were as follow: Pelvocalyces and proximal ureters were demonstrated in 95% or more both on excretory urography and on CT however middle and distal ureters were demonstrate on CT better than on excretory urography . In 6 patients with ureteral obstruction by the extension of uterine cervical carcinoma CT was more informative than excretory urography in respect to the level and the cause of the ureteral obstruction. CT was superior to exvretory urography to confirm the presence or absence of the bladder invasion. From these results we suggest that excretoy urography can be omitted in the era of routine inclusion of CT in the staging work-up of uterine cervical carcinoma.
