Possibility of using the spot camera in the documentation of the arterial phase in urography

: 32 patients have been examined with sequential angiourography (AUS) and image subtraction, utilizing a spot-camera instead of a rapid seriograph, for the visualization of the vascular phase of the renal artery. Satisfactory results have been obtained since in 96.9% of the cases (31/32) it has been possible to obtain representation of those structures sufficient for a clinical evaluation. This technique for its low cost and simplicity of execution can therefore be proposed as a routine examination in the suspect of vascular renal pathology. This method and the more diffuse AUS with rapid seriograph offer, with respect to digital subtraction angiography (DSA), the advantage of a better nephrographic and urographic phase due to the higher quantity of contrast medium injected.
