In Vitro Determination of Optimal Conditions for Coagulum Pyelolithotomy
A clot, suitable for coagulum pyelolithotomy, must have the following properties: (i) the formation must start after 1 min (for optimal mixing and injection) but at the most within 5 min, (ii) the clot must have a good elasticity, and (iii) the clot must be strong (i.e. have good tensile strength). The purpose of this study was to determine the optimal conditions required for the formation of suitable clots. To this end we studied several combinations of cyroprecipitate (cryo), platelet-rich plasma (p.r.p.), thrombin (thromb) and calcium (Ca) under different conditions (temperature, time, dilution) by means of thrombelastography and tensile strength measurements.
