[Diagnostic accuracy of sequential angio-urography with the spot-camera in clinical practice]

In this perspective study the authors examined 57 patients to evaluate diagnostic accuracy of sequential angiourography (AUS) using spot-camera and image subtraction for the visualization of the vascular phase of the renal arteries. All the subjects underwent surgery or follow-up with other clinical and radiological methods. The results obtained with this technique, of low cost and simple execution, were satisfactory: accuracy 98%, sensitivity 100%, specificity 98%.
