Transvaginal sonohysterography for the evaluation and treatment of retained products of conception.

Diagnosing retained products of conception in a woman presenting with postpartum or postabortion bleeding presents a clinical challenge. Although ultrasonographic examination may be potentially useful in detecting retained products of conception, its accuracy has not yet been established. Saline infusion sonohysterography is a simple ultrasonographic technique for enhanced transvaginal sonographic imaging of the endometrial cavity by the instillation of saline into the uterine cavity during ultrasonographic evaluation. This technique enhanced our ability to diagnose retained products of conception, and we describe our experience in evacuating them under sonographic guidance while performing saline infusion sonohysterography.
