Comparison between renal ultrasonography and excretory urography in cervical cancer.
Renal ultrasonography was compared with intravenous pyelography in order to establish the suitability and accuracy of the former investigation as a screening method for ureteric obstruction in patients with carcinoma of the uterine cervix. With a sensitivity of 96.30%, specificity of 96.75%, a positive predictive value of 87.64% and a negative predictive value of 99.09% calculated on a large sample of 420 kidneys, it is recommended that renal ultrasonography is the method of choice in screening for ureteric obstruction in patients with cervical cancer. At the very least it is a suitable and equivalent alternative to intravenous pyelography in such patients.
