Human cryoprecipitated plasma can form an extractable coagulum which will effectively remove renal calculi in selected cases. We successfully used this blood product and a simplified injection technique in 30 patients undergoing surgery for upper tract calculi. Coagulum pyelolithotomy was performed in 24 cases with removal of all stones in 23 (96 per cent). In 6 patients incomplete stone removal by conventional operative methods was successfully completed by using the coagulum as an adjunctive procedure. In 10 of the 30 cases (33 per cent) radiographically "silent" calculi were recovered within the cryoprecipitate clot. The advantages of cryoprecipitate over previously reported blood products, certain technical simplifications, and the appropriate clinical indications for the coagulum procedure are discussed.
人冷沉淀血浆可形成一种可提取的凝块，在某些选定病例中能有效清除肾结石。我们成功地对30例接受上尿路结石手术的患者使用了这种血液制品及一种简化的注射技术。对24例患者实施了凝块肾盂切开取石术，其中23例（96%）的结石全部清除。6例患者通过传统手术方法未能完全清除结石，而使用凝块作为辅助手段后成功完成了结石清除。在30例病例中的10例（33%），X线片显示“隐性”结石在冷沉淀凝块中被发现。本文讨论了冷沉淀相对于先前报道的血液制品的优势、某些技术简化措施以及凝块手术的合适临床适应证。
