X-Ray Photography of the Renal System


    In order that X-ray photographs of the renal pelvis and ureters may be obtained, it is necessary to employ a substance which, after injection into the veins, is excreted by the kidneys and is opaque to the rays, so that a shadow picture of the excretory apparatus of the kidneys may be obtained; further, such a substance must have no harmful effect. A new preparation has been introduced by Glaxo Laboratories, Ltd., under the name of “Pyelectan”, which it is stated possesses the necessary properties in marked degree. Chemically, it is the sodium salt of a complex iodine-containing dicarboxylic acid, the iodine content being 51-5 per cent. Pyelectan is claimed to have a low toxicity and to be generally well tolerated, rapidly excreted by the kidneys and yielding a dense and well-defined shadow in the renal pelvis and ureter.
