Excretory urography in evaluation of the surgical cancer patient.
Excretory urography was performed routinely in 504 patients with sarcoma, melanoma, pelvic, head and neck, or other localized tumors over a 5-year period. There were benign abnormalities in 14.4% of the patients examined, tumor associated abnormalities in 10.7%, and 1.4% false positives. The diagnosis of a benign lesion did not change cancer therapy in any patient. Findings on excretory urography were valuable in the management of patients with pelvic and intra-abdominal tumors. In these patients ureteral obstruction was always caused by tumor. There was a high rate of false positively in non-abdominal tumors. No second primary tumors were found.
