[Value of preliminary intravenous urography. Apropos of errors by default in the ultrasonic diagnosis of renal tumors].
Ultrasound recordings were conducted in 181 patients with renal tumors during a period of three and a half years. A precise diagnosis of a renal tumor mass had not been made in 4 cases, definition of the nature of the lesion requiring further explorations. It is emphasized that in these 4 cases an intravenous urography examination was either not performed (1 case), ultrasound being the initial examination, or was imperfectly conducted and interpreted (3 cases). It is concluded that a correctly performed and interpreted intravenous urography investigation should occupy a preliminary stage before any ultrasound imaging of the urinary tract.
