CT appearance of the pelvis after Cesarean delivery-what is considered normal?

Objective: To describe the normal computed tomography (CT) appearance of the pelvis after uncomplicated Cesarean section (C-section). Patients and methods: Pelvic CT examinations of 31 patients after uncomplicated C-section were reviewed. Results: Higher postoperative day (POD) correlated well with decreases in the uterine long axis and endometrial width but did not correlate to scar width. Full thickness defect of the uterine wall was revealed in 48% of patients. Small volumes of intrauterine gas presented in half of patients at POD 1-26. Free pelvic fluid appeared in 74%. Pelvic collections were rare and small. Conclusion: There is wide variability in pelvic CT appearance following uncomplicated C-section.
