Renal perfusion experiments were performed in thirteen dogs to evaluate the effects of perfusion pressure during normothermic preservation.
Histological examination showed no difference between pulsatile and nonpulsatile perfusion, however, the results of renal function tests showed that pulsatile perfused kidney had better functions than nonpulsatile one, and mean pressure should be maintained higher than 80mmHg to keep better renal functions.
Based on these results, the new pulsatile roller pump was developed for futher investigation. This pump, driven by the stepping motor, is able to control by the electrical control unit. Many types of flow pattern are generated and mean perfusion pressure is able to keep constant by this system.
