Abstract: This study was conducted with the purpose of presenting normal uterus ultrasonographic findings at the 7-10 and 30-40 days after an uncomplicated caesarean section. Abdominal ultrasound was performed on women who underwent cesarean section with the lower segment incision in 222 women at 7-10 and 106 women at 30-40 days after operation. Uterine dimension was measured presences of echo-free fluid, echogenicity of uterine cavity and echogenicity on uterus scar were studied. The uterus length, width and endometrial thickness were 130±20, 59±12 and 6.4±3 mm at 7-10 days after operation, respectively. The uterus length, width and endometrial thickness were 88±20, 46±14, 5.0±3 mm at 30-40 days after surgery, respectively. In 7-10 and 30-40 days after cesarean, echo-free fluid accumulation were observed in 68 (28.6) and 11 (9.6%) of women, echogenicity of intra-uterine cavity were seen in 40 (16.8) and 5 (4.3%) women, echogenicity in the scar area were seen in 102 (42.9) and 38 (33%) of participants, respectively. Pelvic ultrasound is applicable during the postpartum period. Presence of echogenicity and echo-free fluid within the uterine cavity and echogenicity of scar region are repeated finding in patients who are clinically stable.
