EVALUATION OF 170 DIAGNOSTIC PRESSURE-FLOW STUDIES OF THE UPPER URINARY-TRACT

An analysis of 170 pressure flow perfusion studies reveals that they can be valuable in patients of all ages, but particularly so in children, and in a variety of clinical conditions. The complication rate is low and there are few patients in whom these studies do not provide a clear-cut answer on the degree of obstruction. They can be recommended as useful and, at times, invaluable clinical tools.
