Aspects of present and future possibilities for intraluminal pressure recordings in the urogenital tract.

In this brief survey some aspects of present and future possibilities for intraluminal pressure recordings in the urogenital tract are considered. It is emphasized that present water-filled catheter-manometer systems are afflicted with several biotechnical disadvantages. Although the micro-transducers and centre-hole catheters seem to be superior to conventional pressure recording systems, they ought to be further improved. Feed-back pressure transducers, electronic compensation, and micro-manometers could be realistic alternatives for pressure recordings in the urogential tract in the future. Some results from pressure recordings obtained with different measuring systems are presented and discussed.
