sonoelastography: Elasticity is defined as the ability of an organ or tissue to return to its original shape after being deformed by an applied force or stress. Based on this principle, sonoelastography is a technique used to assess the elasticity of tissues and organs during ultrasonography. This assessment allows measurement of changes in stiffness of soft tissues following physiological or pathological processes.
Study summary
The aim of this study is to perform sonoelastographic assessment of the uterus in patients diagnosed with primary dysmenorrhea and to compare these measurements with sonoelastographic evaluations of the uteri in asymptomatic individuals. This will enable, for the first time, the demonstration of whether the elasticity of the myometrial tissue contributes to the etiology of primary dysmenorrhea.
Secondary Objectives: To determine whether there is a correlation between the severity of primary dysmenorrhea and ultrasonographic markers.

Primary outcome measure(s)
SWE Tecnique — 1 year The SWE technique, available in the ultrasound device software, will be used with no additional cost to the patient or institution. With SWE, at least 3 different measurements will be taken from the closest myometrial layer in both axial and sagittal planes, and both speed and elasticity values will be recorded as minimum, maximum, and mean values. The speed of shear waves increases as tissue hardness increases, therefore there is a direct proportion between tissue elasticity and velocity. The elasticity of the tissue is measured with the formula G(tissue elasticity)= ρ(tissue density)c²(shear wave velocity), also called shear modulus. While tissue elasticity is obtained in Kpa, the unit of tissue density is kg/m³ and the shear wave velocity is expressed in m/sn.
