Abstract		Ultrasound and Doppler are one of the most valuable diagnostic tools in evaluating morphology and blood flow conditions of renal transplant, having the most important role in evaluating failing renal graft. Examination enables quick, noninvasive and reliable exclusion of all extraparenchymal causes of graft failure (urinary tract obstruction, occlusion of major vessels, renal artery transplant stenosis) and proceeding to ultrasound guided graft biopsy (that is necessary for diagnosis of rejection), often without need for other diagnostic procedures. Comparing Doppler findings to renal scintigraphy and angiography revealed excellent accuracy. Doppler examination can be performed at a bedside and, if needed, as intra or peri-operative examination for the patients at risk of vascular problems. Ultrasound-Doppler is ideal for long-term follow-up and is the method of choice in the assessment of vascular complications after renal transplantation in children as well as in adults. In the last years the use of ultrasound contrast agents intravenously (the new generation passing pulmonary circulation) became popular improving sensitivity of Doppler studies. Their use was further extended intravesically, for detection of vesicouretheral reflux in renal transplant recipients.
