Background: post placental intrauterine device (IUD) insertion is effective, convenient strategy to reduce the risk of rapid repeated pregnancy. Objectives: To evaluate abnormal uterine bleeding (AUB), infection, loss of threads, displacement, expulsion, and pregnancy on top, regarding two post placental IUD insertion techniques. Patients and Methods: Cohort prospective comparative study was conducted on 164 women in the Obstetrics and Gynecology Department, Menoufia University Hospital, during a period time from September 2022 to December 2022. Results: Significant differences among the studied two groups regarding IUD displacement (p=0.029), AUB (p=0.001), loss of threads (p=0.036) and IUD expulsion (p < 0.001) after 6 weeks of IUD insertion, and a significant difference regarding IUD displacement and loss of threads after 3 months of IUD insertion (P<0.05). Conclusions: Because the new approach is linked to a decreased frequency of IUD displacement and non-visibility of IUD threads, it may become the standard procedure for intra-cesarean section IUD insertion.
