pressure increases because the catheter reaches the beginning of the
urethra), the transducer measuring the urethral pressure (P
bladder; hence, this is the resting bladder pressure.

MUCP is the maximum difference between the urethral pressure (P
bladder pressure (P
between the Profile start marker and the Profile end marker.
Calculated: Urethral closure pressure = [D] = [E]-[F].
MUCP is only calculated when the Profile start marker is present.
Total profile length
The total profile length is the length of the urethra along which the urethral
pressure exceeds 0 cmH
in conjunction with the time needed for the urethral pressure (Pura) to reach
0 cmH O. Pura=0 indicates the end of the urethra, providing the transducers

were zeroed at atmospheric pressure.
Calculated: Profile length = Pullerspeed*[T@(Pura=0) – Tprofile].
A profile end marker can be placed before Pura reaches 0 cm H
profile length is then calculated as the product of the puller speed and the time
between the profile begin marker and the profile end marker.
Calculated: Profile Length = Pullerspeed*[Tprofile end – Tprofile begin].
Total profile area
The total profile area is the area under the urethral pressure curve [G]+[H].
Proximal area to peak
The proximal area to peak is the area indicated by [G]. It is the area under the
urethral pressure curve between the profile start marker and the peak.
Distal area to peak
The distal area to peak is the area indicated by [H]. It is the area under the
urethral pressure curve from the peak until the urethral pressure reaches 0. If
a profile end marker is placed, the distal area is the area under the urethral
pressure curve from the peak to the profile end marker.
