Hysteroscopy for retained products of conception: a single-institution experience

Retained products of conception can occur with induced abortion during early-term pregnancy, induction of labor during mid-term pregnancy, drug-induced abortion, miscarriage, cesarean delivery, or full-term normal delivery. Compared with traditional dilation and curettage, hysteroscopy is a safer and more effective treatment method for retained products of conception. This study aimed to report the efficacy of hysteroscopy for treating retained products of conception and to share our new clinical perspectives.

This retrospective, single-center study was conducted at a tertiary hospital in Chengdu, China. We included 36 patients with retained products of conception who underwent hysteroscopy at our hospital.

Our study reported a complete removal rate of 80.5% (29/36) with one procedure. The normal menstruation recovery rate during 1 year of follow-up was 91.6% (33/36). A low rate of postoperative intrauterine adhesions (2.8% [1/36]) was also reported.

Our retrospective study elucidated the use of hysteroscopy for retained products of conception. We also shared new perspectives regarding hysteroscopy and optimal surgical methods for treating retained products of conception as well as our experience treating residual products with hysteroscopy. To our knowledge, no other study has shared similar experiences.
