The authors report an experiment using the cadaver kidney with a fibrin coagulum injected into the pelvis and calices in order to extract multiple calculi. They used a mixture of cryoprecipitated plasma and a combination of thrombin and calcium chloride. This mixture was made up immediately before use, and injected into the pyelocaliceal cavities using a small Foley catheter previously inserted into the renal pelvis. This catheter was used to empty completely the pyelocaliceal cavities of urine immediately before injection. Extraction via a pyelotomy incision was used to withdraw the compact mold which had imprisoned the stones. In 20 kidneys studied experimentally, removal of stones was complete in only 12. The authors blamed this on their initial technical inexperience. The limitations and advantages of the method are discussed.
作者报告了一项实验，该实验使用注入纤维蛋白凝块至肾盂和肾盏的尸体肾脏来取出多个结石。他们使用了冷沉淀血浆的混合物以及凝血酶和氯化钙的组合。这种混合物在使用前立即配制，并通过先前插入肾盂的小Foley导管注入肾盂肾盏腔内。在注射前，使用该导管将肾盂肾盏腔内的尿液完全排空。通过肾盂切开术切口取出包裹结石的紧密铸型。在20个用于实验研究的肾脏中，仅12个肾脏的结石被完全取出。作者将此归咎于他们最初的技术经验不足。文中讨论了该方法的局限性和优点。
