== Urethral pressure profilometry (UPP) ==

* '''Definition of urethral pressure: fluid pressure needed to just open a closed urethra'''
** Clinical relevance is controversial
* Several parameters can be obtained from the UPP:
** Urethral closure pressure profile: urethral pressure – intravesical pressure
** Maximum urethral pressure: highest pressure measured along the UPP
** Maximum urethral closure pressure (MUCP): maximum difference between the urethral pressure and the intravesical pressure
** Functional profile length: length of the urethra along which the urethral pressure exceeds the intravesical pressure in women
*** In most continent women, the functional urethral length is ≈3cm and the MUCP is 40-60cm H2O, but normal values vary widely
