CORRELATION BETWEEN URETHRAL SPHINCTER ACTIVITY AND VALSALVA LEAK POINT PRESSURE AT DIFFERENT BLADDER DISTENTIONS: REVISITING THE URETHRAL PRESSURE PROFILE

There is a significant correlation between maximum urethral closure pressure and LPP. Patients with a LPP of 60 cm H2O or less have a shorter urethral functional length and lower sphincter activity. Patients with SUI have a more remarkable correlation between UPP and Valsalva LPP when UPP is determined after filling the bladder to more than 200 ml.
