The efficiency o f a ureteric compression device is based on its p r o p e r positioning and the maintanence of an adequate level o f abdominal compression to obstruct the ureters against the psoas muscle and other retroperitoneal structures. The most widely used pneumatic devices are either the dual or single large balloon systems. The dual balloon system is favored because it exerts pressure on either ureter and not on midline structures [1]. The positioning of these devices can be easily taught and visually checked. More accurate determination of their application through either fluoroscopy or filming is possible. However, visual inspection of the degree of inflation of the balloons does not adequately monitor the pressure, and few, if any, units are supplied with the pressure recording device. An easy addition to the
currently available pneumatic units is the replacement o f the insuffiating bulb with a s p h y g m o m a n o m e t e r insuffiating bulb (Fig. 1). Appropriate pressure is exerted when the inflation level is listed at 250 300 m m Hg. Leakage in the system during the examination can then be identified, and adequate compression is maintained t h r o u g h o u t the study.
