Diagnostic accuracy and characteristics of symptomatic versus asymptomatic retained products of conception: A retrospective cohort study.

Objective: To assess the accuracy of diagnosing retained products of conception (RPOC) in symptomatic versus asymptomatic women, and to identify potential divergent ultrasound features between these groups.

Methods: This retrospective study included women aged 17-50 years who underwent hysteroscopy for suspected RPOC during 2018-2021. Clinical and sonographic data were analyzed, and multivariable linear regression models employed, to examine correlations between RPOC and sonographic findings, and to compare diagnostic accuracy between symptomatic and asymptomatic women.
