Simultaneous urethrocystometry and urethra pressure profile measurement with a new technique.
A new technique for simultaneous recording of the pressures within the urethra and urinary bladder is described. The pressures are recorded by microtransducers enclosed in a semiflexible dacron catheter. The recording system has a high frequency response (2000 HZ) and is free of motion-induced artefacts, which makes it possible to measure the urethra pressure profile with a high degree of precision.
