Hepatorenal Syndrome is one of the most common complications of hepatic cirrhosis. Once it happens, the prognosis is usually very poor and also with highly fatality. Most of the hepatorenal Syndrome is developed from chronic B hepatitis and hepatic cirrhosis. At the early period , this kind of renal lesion is reversible. But if without timely improvement, the renal lesion may turn to hepatorenal syndrome, and that is inreversible. From above, early treatment on renal lesion from hepatitis and hepatic cirrhosis and early diagnosis is very important, and it is the key point to improve the prognosis and the survival rate.Recently, with the development of ultrasound, CDVP can make the rate profiles by the blood video picture signal of color Doppler, not only describe the profile distribution of the blood flow rate, measure the transient blood of vessel section directly, but also tell the result automaticly, overcome the calculation of blood and the limitation of accuracy. Histogram is a kind of non-spectrum blood quantitate analyses technology which based on the color blood signal of the blood direction and rate from the cross-section of the blood vessels. It is different from the CDFI and CDEI technology, both of those methods can only describe the blood signal of the renal by visual measurement, because of this, those two methods are not objective. The use of Histogram is more objective and accurate. CDVP and Histogram overcome the shortage of the intrinsical technology, and have shown the peculiar superiority on the hemodynamics.The study used Aloka Prosound SSD-5500 (made in Japan) with CDVP and Histogram system. Divided the sample into hepatic cirrhosis group(55cases), chonic B hepatitis group(30cases) and control group (30cases), detected the blood flow of renal main- artery, portion- artery, lobus- artery, and arch- artery. And calculate the percentage of renal blood flow and renal area.The consequence of the study showed, with the progress of the disease, the renal hemodynamics of the hepatitis and hepatic cirrhosis patients has changed. The blood flow of the renal is lower, and the renal hemodynamics is hypoperfusion. By CDVP, the renal blood flow is significantly lower in hepatic cirrhosis group compared with hepatitis group, the contrast is significance (P<0.01).The renal blood flow is significantly lower in hepatic cirrhosis group compared with control group, the contrast is significance (P<0.01). The renal blood flow is also lower in hepatitis group compared with control group, but only significantly in the main- artery and portion- artery(P<0.01), in the lobus- artery,and arch- artery only showed the difference(P<0.05). Compared among the three groups, the blood flow showed control group > hepatitis group > hepatic cirrhosis group. Using Histogram, we can see that the blood signal is most abundance in the control group, main- artery ,portion- artery and lobus- artery just like branches, arch- artery is continuous, there are plenty of little lobus- artery in the cortex. In the hepatitis group, the renal blood flow turned lower, arch- artery is continuous, but the ittle lobus- artery in the cortex turned raritas. The renal BCR is significantly lower compared between hepatitis group and control group (P<0.01). When the hepatic cirrhosis happens, the renal hemodynamics changed significantly, the lobus- artery became asynechia, the arch- artery seems like shining stars, little lobus- artery in the cortex can not be seen, only main- artery and portion- artery can be seen clearly. The renal BCR is significantly lower compared between hepatic cirrhosis group and control group (P<0.01). And the consequence is the same in the comparison between the hepatic cirrhosis group and the hepatitis group (P<0.01). The renal BCR is control group > hepatitis group > hepatic cirrhosis group in the comparison. And the the contrast is significance (P<0.01). From the above all, we can draw a conclusion that the renal vessels lesion is happen with the little blood vessels in the hepatitis and hepatic cirrhosis patients, and the vessel is thiner the lesion is more serious.Taking into account all of these factors, we can draw the conclusion that detecting the renal hemodynamics lesion in hepatitis and hepatic cirrhosis patients by CDVP and Histogram is convenient, simple, objective, no wound, precise ,easy to receive and good reproducibility. it can offer regular, multiple detection of the renal blood flow and BVR in the hepatitis and hepatic cirrhosis patients. By these two methods, we can make an objective comprehension of the renal hemodynamics in hepatitis and hepatic cirrhosis patients. And can detect the perfusion of the renal . The mose important thing is that it is meaningful to judge the early renal lesion in the progress of hepatopathy. The detection of renal hemodynamic is an objective index which can respond the early lesion of the renal, and it also make a significant sense of the early renal lesion in the hepatitis and hepatic cirrhosis patients.
