Detailed Description

Women who naturally deliver a singleton in the Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital will be invited to participate the study. Weekly transabdominal and/or transvaginal ultrasound examinations will be offered until the uterus is completely involuted. Transabdominal or transvaginal approach will be at the examiner's discretion. Uterine volume will be measured with 3-dimensional sonographic technologies. Ovaries will also be assessed, along with Doppler flow in several vessels in the pelvis. The pattern of involution will be analyzed.
