WITH INCREASING frequency hypertension associated with unilateral renal disease has been recognized and treated. Its recognition has increased the importance of the excretory urogram as a screening technique. Because of inadequate filling of the renal pelvis and calyces with contrast material, numerous techniques to improve their visualization have been developed. These include abdominal pressure and the prone and Trendelenburg positions.1 These methods have not resulted in the complete filling of the renal pelvis needed for successful examination.

A technique for unilateral urine sampling has been described recently whereby the ureters can be occluded by external compression.2 During this study an incidental observation was that the excretory urogram was improved on the occluded side. The purpose of this paper is to present experiments designed to test whether or not external ureteral compression significantly improves the diagnostic quality of excretory urograms.
