“…In this manuscript, we aimed to evaluate a novel methodology for the measurement of vaginal wall thickness utilizing a transvaginal biplanar ultrasound probe. For the measurement of vaginal wall thickness (VWT), various ultrasound techniques have been proposed in the literature [ 3 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ], both transabdominal and transvaginal and both 2D and 3D at high frequency. Panayi first described a transvaginal US technique to measure the thickness of the vaginal wall at various anatomical sites, including the bladder neck, anterior and posterior fornix, and rectum [ 21 ].…”
