Summary
This study compared four intrauterine devices (IUDs) in postpartum women. The stainless steel IUD (SSR) showed higher discontinuation rates due to pregnancy and expulsion compared to other IUDs.
Area of Science:
- Reproductive Health
- Medical Devices
- Gynecology
Background:
- Postpartum contraception is crucial for maternal health and birth spacing.
- Intrauterine devices (IUDs) are effective long-acting reversible contraceptives.
- Comparing different IUD types is essential for optimizing postpartum family planning.
Purpose of the Study:
- To evaluate and compare the performance of four different intrauterine devices (IUDs) in women 3-9 months postpartum.
- To analyze termination rates and reasons for discontinuation among the studied IUDs.
Main Methods:
- A single-blind randomized controlled trial involving 710 healthy women aged 22-32 years.
- Women were allocated to one of four IUD types for postpartum use.
- Data collected over 2 years, analyzed using logrank test for termination rates.
Main Results:
- Significant differences observed in crude and cumulative termination rates among the four IUD groups.
- The stainless steel ring (SSR) exhibited a significantly higher crude termination rate compared to MLCu250, UCD, and TCu 220C (P < 0.01).
- Primary reasons for SSR discontinuation were pregnancy and expulsion; MLCu250 showed the lowest removal rates for bleeding and pain.
Conclusions:
- The stainless steel ring (SSR) demonstrates a higher discontinuation rate in the postpartum period, mainly due to pregnancy and expulsion.
- MLCu250 appears to be the most suitable IUD for postpartum use concerning bleeding and pain-related removals.
- UCD and TCu 220C also showed varying performance profiles regarding termination and removal reasons.
