Hysteroscopy and Retained Products of Conception

Hysteroscopy is considered the gold standard for the diagnosis of intrauterine pathology including gestational retained products. The hysteroscopic appearance of this pathology varies depending on the involution, vascularization and the degree of necrosis of the trophoblastic retained tissue, which results in no single hysteroscopic pattern. This is because the retained tisue undergoes a process of involution over time that makes changes in their macroscopic appearance, so it is important to know the different macroscopic aspects that this pathology presents.

The Gutenberg classification correlates the different ultrasound patterns with the hysteroscopic appearance of RPOC, which allows to anticipate the complexity and degree of difficulty that may be encountered at the time of uterine evacuation.
