Objective: To study and compare the clinical efficacies and characteristics of VCu intrauterine device (IUD) and TCu380A IUD in childbearing-aged women with previous cesarean section so as to provide rationales for an informed choice of contraceptive methods.
Methods: According to their physical status, a total of 400 women undergoing previous cesarean section were randomly provided VCu IUD and TCu380A IUD from February 2008 to August 2009. These healthy women were had no contraindication to IUD. The volunteers required voluntarily the placement of IUD. Then all of them were followed up for 3, 6 and 12 months.
Results: At Month 12, the pregnant rate with IUD in situ of VCu and TCu380A IUD were 1.02% and 4.64%, expulsion rate 0 and 3.1% and withdrawing rate 1.02% and 4.13% respectively. The pregnant rate was significantly different (P < 0.05); VCu showed a lower expulsion and withdrawing rate than that in TCu380A (P < 0.05); the continuation rate of VCu was higher than that of TCu380A (P < 0.05).
Conclusion: VCu offers a better efficacy of contraception with a lower expulsion and withdrawing rate, a higher continuation rate and a simpler placement method.
