Elevated puborectalis stiffness measured by endovaginal shear wave elastography is associated with obstructed defecation syndrome

Abstract Obstructed defecation syndrome (ODS) is a common functional disorder in which conventional B-mode ultrasound demonstrates abnormal puborectalis muscle (PRM) behaviour but cannot quantify intrinsic tissue mechanical properties. Shear wave elastography (SWE) provides a qua...
