Three-Dimensional Transvaginal Ultrasound (3D TVS)
Saline-Infused Sonography (Sonohystrography)
In this study, Three-Dimensional Transvaginal Ultrasound will be employed as one of the interventions to evaluate Cesarean Scar Defects (CSD) and associated complications in symptomatic patients with a history of cesarean section. A specialized ultrasound machine (Samsung WS80A) equipped with a transvaginal 2-11 MHz probe will be used for the Three-Dimensional Transvaginal Ultrasound examination. The examination will be conducted in the 1st half of the menstrual cycle. The ultrasound probe will be introduced into the posterior fornix of the vagina to capture three-dimensional images of the uterus and scar area. The examiner will identify and measure the characteristics of the Cesarean Scar Defects (CSD), including length, depth, width, volume, residual myometrial thickness, adjacent myometrial thickness, and presence of any branches.
The Sonohystrography will be performed using a Toshiba ECCO CEE SSA-340A ultrasound equipment with a 7.5 MHz transvaginal probe. A sterile vaginal speculum will be inserted, the cervix cleansed with an antiseptic solution, and a thin Foley's catheter inserted into the cervical os. Sterile saline solution will be infused into the uterus through the catheter to distend the uterine cavity. The examiner will use the ultrasound probe to visualize and assess the uterine cavity, focusing on identifying and measuring Cesarean Scar Defects (CSD) characteristics, including depth, width, volume, and myometrial thickness.
