title: Polymeric pyelotomy (experimental studies).
abstract: A non-toxic, soluble polymeric preparation MAG with controlled period of gelation was synthetized for the extraction of stones from the pyelocalyceal system during surgery for urolithiasis. With respect to toughness the preparation proved superior to the fibrinogen-thrombin mixture, used in the so-called "fibrin pyelotomy" according to Dees. Its biologic testing in animals (rabbits, dogs and pigs) yielded excellent results.
