The value of urography after angiocardiography. A survey of 300 cases

Routine films were taken of the kidneys after contrast studies of the heart and great vessels in 300 consecutive patients using the Sircam 100-mm camera. A significant amount of information was obtained at low cost and with minimal radiation of the patient. A standard was established for normal sizes of kidneys using this format. There were 56 abnormalities, including 26 pairs of kidneys that differed significantly in size (19% and 9%). There were 2 tumors, 2 cysts, 19 congenital abnormalities, 1 renal artery stenosis, 4 renal and 1 biliary stone. One of the tumors, undetected at a previous angiographic examination, was inoperable, and earlier detection would have undoubtedly benefited and may have offered a possible cure to this patient. The authors feel that the addition of this examination, trifling in the expenditure of time and money, is of definite benefit to the patient. (orig.)
