Expulsion rate of intrauterine device: mediate vs. immediate puerperium period

Abstract

Objective: To evaluate the rate of expulsion of intrauterine device (IUD) inserted during the immediate and mediate puerperium. To evaluatewhether the type of delivery is a predictor of expulsion of the IUD when inserted in the puerperium period.Material and Methods: This was a prospective observational study. Patients whose IUD (TCU-380 copper) was placed during the puerperalperiod were divided in two groups according to the time of placement: immediate and mediate puerperium. The decision regarding the time ofIUD insertion was made in a non-randomized manner. Analysis was performed using chi-square, Mann-Whitney U, and Spearman’s correlationtests and logistic regression analysis.Results: The total rate of IUD expulsions was 28.8% (49/170). There was no significant association between the occurrence of expulsion and thetiming of IUD insertion (immediate vs mediate puerperium; 26.6% vs 34.78%, p=0.296). Among patients experiencing expulsion, 79.6% (39/49)underwent insertion after vaginal delivery and 20.4% (10/49) during cesarean section (CS). The type of delivery was a significant predictor forIUD expulsion (p
