Screening for urinary tract abnormalities with single-film urography after phlebography and angiography.
Single-film urography was performed after phlebography or angiography in 2,335 patients. Abnormal results were reported in 52 of these patients. Subsequent complete urography verified two significant abnormalities (one renal calculus and one renal cell carcinoma). In addition, there were 28 less significant abnormalities. In 22 patients the single-film urography was incorrectly reported as abnormal. Among the 2,283 normal single-film studies there were three cases of false-negative results (two renal cell carcinoma and one renal calculus with perinephritis). This study does not confirm the value of routine single-film urography after phlebography and angiography.
