Abstract:
Objeetive To investigate the changes of kidney cortex hemoperfusion before and after extracorporeal shock wave lithotripsy (ESWL) with contrast-enhanced ultrasonography (CEUS) and time-intensity curve.Methods Thirty patients of renal calculi were treated with ESWL and examined with CEUS before and after ESWL.Renal cortex blood perfusion parameters of the lithotriptic areas,including the contrast agent arrival time (AT) ,time to peak (TTP) .peak intensity (PI) and velocity parameters (β) were quantitatively measured with ACQ software.Results The value of AT,TTP and β were not significantly different before and after ESWL (P＞0.05) .PI value after ESWL was lower than that before ESWL (P＜0.05) . Conclusion CEUS can quantitatively evaluate the changes of kidney cortex hemoperfusion after ESWL,and reflect the minor renal damage resulted from ESWL.CEUS can be used as a new method of observing and evaluating the renal damage caused by ESWL.
