There are different causes of abnormal uterus bleeding. Foreign body is a less common etiology due to the increasing rate of cesarean delivery. We are confronting some uncommon complications of cesarean section. Uterine incision closure is a substantial step in cesarean section. Since suture material hydrolysis is affected by patient different features, impaired suture material degradation in uterus scar may cause some complications like abnormal uterine bleeding.

We reported a 49-year-old woman who had abnormal uterine bleeding with prior history of multiple cesarean section. During hysteroscopy, abnormal mass was seen in anterior surface of uterine cavity compatible with the level of internal os. Polypectomy and removal of foreign body followed by endometrial curettage were performed. After hormonal assay and sonography evaluation, the patient underwent hysteroscopy and foreign body was observed in anterior surface of uterus. She was followed and visited 6 month after operation and she had no abnormal bleeding. Perhaps this foreign body led to abnormal uterine bleeding.

Patient characteristics has important role in suture material degradation. Impaired suture hydrolysis in uterus incision may cause abnormal uterine bleeding. It is interesting to demonstrate whethersuture degradation in previous cesarean section has a role in formation of placenta accrete or not .This issue needs more investigation. Because there is no similar case in literature, we cannot compare our article with others.
