Coagulation pyelolithotomy provides an effective means to remove multiple calculi from the renal collecting system. The strength of the coagulum is directly proportional to the concentration of fibrinogen and inversely proportional to the concentration of thrombin. Because of the fear of hepatitis fibrinogen may soon be unavailable commercially. It will then become necessary to use plasma from the patient as the source of fibrinogen. By the process of cryoprecipitation fibrinogen levels can be increased about 10-fold, yielding clots of greater tensile strength than would be obtained from non-concentrated plasma.
凝血肾盂切开取石术为从肾集合系统中取出多个结石提供了一种有效的方法。凝块的强度与纤维蛋白原浓度成正比，与凝血酶浓度成反比。由于担心肝炎，纤维蛋白原可能很快在商业上无法获得。届时将有必要使用患者的血浆作为纤维蛋白原的来源。通过冷沉淀过程，纤维蛋白原水平可提高约10倍，产生的凝块比非浓缩血浆获得的凝块具有更大的抗张强度。
