[Color-coded Doppler sonography of kidney transplants].

A prospective study was carried out in 81 patients to compare the ability of colour coded Doppler sonography (angiodynography) and Tc bolus examination for demonstrating renal blood supply. In patients with normal transplant function both methods performed equally well. In anuric patients angiodynography was superior to the Tc bolus examination: In three cases angiodynography was able to provide important additional information such as absence of blood flow in peripheral intrarenal vessels or missing blood supply of a transplant pole. Angiodynography seems to be able to replace the Tc bolus examination; this statement excludes very obese patients until low-frequency probes for angiodynography will be available.
