Sonographic findings in acute puerperal endometritis.

Purpose: To evaluate the reliability of the sonographic subserosal hypoechoic rim sign and endomyometrial junction indistinctness in distinguishing patients with acute puerperal endometritis from other common postpartum complications, particularly those with retained products of conception.

Methods: Radiographic coding identified all patients presenting to Auckland City Hospital over a 12-month period between 1 March 2016 and 28 February 2017 who had pelvic ultrasound scans to assess for postpartum complications. Clinical notes were reviewed to identify those patients with a clinical diagnosis of acute endometritis.

Sonographic findings in acute puerperal endometritis: The hypoechoic rim sign and endomyometrial junction indistinctness.

Purpose: To evaluate the accuracy of the sonographic subserosal hypoechoic rim sign and endomyometrial junctional indistinctness in identifying patients with acute endometritis during the puerperal period.

Methods: Radiologic coding identified the ultrasound scans of all patients presenting to Auckland City Hospital between January 2014 and February 2016 who were diagnosed clinically as having acute endometritis during the post-partum or post-abortion period. After exclusion criteria were applied, the ultrasound scans of 31 patients with acute endometritis and 32 healthy controls were randomised and anonymised.
