The graphs presenting differences in values of the intensity of perfusion (I mix ) in the midurethra between nulliparous and multiparous patients, measured in the axial section of the urethra. Majority of multiparous patients had the value of Imix ≤0.01, and the highest value of Imix = 0.04. In nulliparous patients the values of Imix varied, ranging from ≤0.01- 0.07.
