Dual pressure transducer catheter for evaluating vesicourethral function: experiences in patients with neurogenic...

Preliminary experiences with a dual pressure transducer catheter (7 F) for the functional vesicourethral evaluation are described. Synchronous cystosphincterometric recording, urethral pressure profile with simultaneous intravesical pressure, and pressure gradient across urethral sphincter were obtained. Comparison of the studies with those conducted with catheter infusion technique revealed that minimal artefacts were encountered with the former although the pressure events displayed by the two methods were grossly similar.
