| Abstract | OBJECTIVES: To assess by ultrasound examination the success of insertion of an intrauterine contraceptive device (IUD) immediately after delivery and to determine the optimal distance between the lower end of the IUD and the internal os in predicting successful retention of an IUD. METHODS: This was a prospective study carried out between December 2012 and April 2013. Two ultrasound examinations, transabdominal and transvaginal, were performed prior to hospital discharge following delivery and again at 6 weeks following delivery in women who received a postpartum IUD. Distance from the internal os to the lower end of the IUD was measured at each examination and compared in unsuccessful and successful cases of postvaginal delivery (PVD) and post-Cesarean section (PCS) IUD insertion. Logistic regression and receiver-operating characteristics (ROC) curve analysis were used to determine the difference in success between the two modes of delivery and to determine the optimal cut-off of the internal os-to-IUD distance for successful retention, respectively. RESULTS: Ninety-one women were included in the study, comprising 60 PVD and 31 PCS IUD insertions. Thirteen PVD (22.4%) and eight PCS (25.8%) IUDs were either expelled spontaneously or removed at the 6-week scan because of improper placement. Mean distance from the internal os to the lower end of the IUD on ultrasound examination immediately after insertion was significantly greater in successful cases than in those in which IUDs were subsequently expelled/displaced (mean difference after PVD insertion, 20.1 mm (P = 0.006); mean difference after PCS insertion, 10.3 mm (P = 0.05)). Logistic regression analysis demonstrated that mode of delivery was not independently associated with successful retention of the IUD (P = 0.72; OR, 0.831 (95% CI, 0.301-2.189)). The distance from the lower end of the IUD to the internal os measured at ultrasound examination prior to hospital discharge provided reasonable predictive accuracy for determining retention of the IUD, with an area under the ROC curve of 0.74 (95% CI, 0.60-0.88) and an optimal cut-off of ≥ 30 mm (sensitivity, 64.71% (95% CI, 52.17-75.92%) and specificity, 80.95% (95% CI, 58.09-94.55%)). CONCLUSIONS: IUD insertion immediately postpartum is feasible but carries a substantial risk of unsuccessful IUD retention. Ultrasound examination after insertion of an IUD could be considered for predicting the success of IUD retention. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
