Some methodiological aspects on the measurement of intraluminal pressures in the female urogenital tract in vivo.

This short survey presents some methodological aspects on intraluminal pressure recordings in vivo from the female urogenital tract. The importance of adequate calibration is stressed and a calibration unit for different types of recording equipments is described. Calculations of measuring errors are outlined. The selection of recording catheters is disucssed from both the theoretical and the practical point of view. Finally some practical aspects are considered on pressure recordings in vivo from the ureter, the bladder, the urethra and the uterus. This discussion is illustrated by pressure diagrams obtained with different recording techniques from the actual organs.
