ABSTRACT: Objectives: This study focused on evaluating the value of transvaginal 3D
ultrasound for the diagnosis and prognostic assessment of post-cesarean section
uterine diverticulum. Materials and Methods: We retrospectively analyzed the data
from 32 patients with post-cesarean section uterine diverticulum over three recent
years. In all patients, transvaginal 3D ultrasound was used to measure the size
of the uterine diverticulum and the thickness of the lower uterine segment (LUS)
and myometrium. Patients with a LUS with a myometrial thickness under 4 mm underwent
resection and repair surgery; those with a LUS with a myometrial thickness over
4 mm underwent hysteroscopic resection. The postoperative sonograms were compared
with preoperative images to evaluate the efficacy of various treatments. Results:
The mean length, width and depth of the uterine diverticula were 18.30 ± 2.80 mm,
9.14 ± 3.20 mm and 11.49 ± 2.71 mm, respectively. The average LUS myometrial thickness
was 3.40 ± 0.80 mm (with a range of 1.6 mm - 6.3 mm). After surgery, two patients’
sonograms still showed diverticula at the post-cesarean section scar, measuring
6 mm × 7 mm × 6 mm and 6 mm × 8 mm × 4 mm. There were significant differences in
the size of uterine diverticula between preoperative and postoperative sonograms
