Fiberoptic microtransducer pressure technology: urodynamic implications.
The FST 200 is a novel commercially available pressure measurement system that combines microtechnology and fiberoptics and is particularly well suited for invasive urodynamic studies. Pressure recording with this system is highly accurate and reproducible. The pressure curves obtained parallel those from standard water cystometry. Being small and portable, the system lends itself to invasive transurethral monitoring in the privacy of an examination room. Additionally, the 5F catheter size allows the performance of leak point pressures and pressure/flow voiding studies with minimal urethral stenting artifact often seen with larger catheters. The technical aspects of this system are presented.
