Diagnosing IUD malposition is a critical skill for gynecologists and primary care providers. Recent research highlights that clinical symptoms and physical exams often fail to detect a displaced device. Because intrauterine devices (IUDs) are widely used in India for family planning, understanding their correct placement is essential for patient safety.
A retrospective review of 175 patients revealed that nearly half were completely asymptomatic. Among those who reported symptoms, pelvic pain and abnormal uterine bleeding were most frequent. However, the study confirms that visible strings on a physical exam do not guarantee correct placement. Consequently, clinicians must maintain a high index of suspicion. Low intrauterine placement is the most common IUD malposition pattern observed. Furthermore, patient demographics like BMI do not significantly predict displacement risk.
Ultrasound remains the gold standard for evaluating device location. While two-dimensional imaging is common, three-dimensional ultrasound offers superior accuracy for detecting embedding or partial perforation. Therefore, imaging should be ordered whenever a patient reports new-onset pain or if the strings are missing. Since many malpositioned devices remain silent, routine imaging may be considered in high-risk scenarios. Moreover, proper diagnosis prevents complications like unplanned pregnancy or uterine injury.
It depends on the location. A low-lying copper IUD significantly increases the risk of contraceptive failure, whereas a hormonal IUD might still provide some protection. However, removal and replacement are generally recommended to ensure efficacy.
No. Visible strings only confirm the device is still in the uterus, but they cannot verify if it is fundally positioned or embedded in the muscle. Ultrasound is required for precise verification.
