Additional value of triple-sensor urethral catheter in demonstrating urethral pressure variations during filling cystometry.

There is an additional value in measurement with the triple urethral-sensor catheter for demonstration of UPV during filling cystometry. Currently, continuous measurement of urethral pressure during filling cystometry and UPV is not defined within International Continence Society terminology. The single urethral-sensor catheter is useful for a start, however, it demonstrates less than half of all UPV.
