X-ray examination of IUD

The X-ray examination of the IUD can determine the position and shape of the IUD and determine if there are any abnormalities to ensure the contraceptive effect. Generally, the use of standing perspective and the application of TV perspective make the X-ray inspection of the IUD very convenient and clear. Fluoroscopy, need to reduce the aperture to observe carefully, in case of obesity, you must pressurize the lower abdomen, so that a part of the fat tissue can be seen. The lying position is easier to see than the standing position, because the lower abdomen is flat when lying, which is good for observation. If there is suspicious should be observed. Basic Information Specialist classification: gynecological examination classification: X-ray Applicable gender: whether women are fasting: not fasting Tips: Check should be 3-7 days after menstruation is clean. Normal value There are many types of birth control devices, such as circular birth control rings, T-shaped IUDs, Y-shaped IUDs, V-shaped IUDs, twist rings, and birth control rings. The most used in China is the birth control ring. In the standing position examination, the general birth control ring is located 2 to 6 cm above the pubic symphysis, and within 3 cm of both sides of the midline. When the standing position and the lying position are inspected, the position of the birth control ring may vary from 0.5 to 4 cm. Since the position of the uterus in the pelvic cavity is not fixed, and the uterus itself often has different degrees of forward tilting, backward tilting or tilting, the position and shape of the birth control ring are also greatly different. The shape of the birth control ring is mostly circular or elliptical. The anteversion or backward tilting of the uterus makes the ring shadow elliptical, and the extreme forward or backward tilting makes the ring shadow appear "one". Clinical significance Abnormal results: 1. Illegal ring break: The fracture marks are visible. When completely broken, the two broken ends are in a "V" shape in the same direction, and the two broken ends are linear in the opposite direction. After the ring breaks, it is easy to break through the uterine wall and enter the abdominal cavity. 2. The birth control ring is distorted: The multi-system uterine cavity is too small or asymmetrical, so that the birth control ring is not fully bounced and distorted. The ring shadow can be "8" shaped, small round, triangular, etc. 3. The birth control ring is removed from the cervix or vagina: The rate of shedding ring is about 10%, and the reason for shedding is: 1 Immune size is not suitable; 2 improper position in the uterus; 3 IUD deformation; 4 uterus sensitive to foreign bodies, increased contractility; 5 uterine malformations; Take the ring out. X-ray performance: 1 ring shadow is longitudinal "1" shape or oblong; 2 ring shadow position is lower than or overlapping with pubic bone. 4. The IUD enters the abdominal cavity: The main reasons for the birth control device to enter the abdominal cavity are as follows: 1 the surgical instrument damages the uterine wall, or the force is too strong, causing the IUD to be embedded in the uterine wall or penetrating into the abdominal cavity; 2 due to the contraction of the uterus, the pressure causes the IUD to penetrate into the abdominal cavity through the muscle wall of the uterine wall; 3 The uterus strongly contracts or the fallopian tube relaxes, and the IUD enters the fallopian tube and is discharged into the abdominal cavity. X-ray performance: 1 IUD position is too high or off-center distance is large; 2 IUD activity range is large, up to the pelvic edge; 3 ring education deformation, can be long, half-moon shape; 4 pelvic area see ring Shadow, exploration of the atrium without a ring; 5 cases of difficult to diagnose can be used for hysterosalpingography, see the ring shadow outside the official cavity. 5. With IUD pregnancy: Due to the discomfort of the size of the device, the position may be improper, and a ring pregnancy may occur. X-ray performance: 1 position of the early pregnancy device, the shape can be no abnormality; 2 with the uterus increased, the position of the IUD is abnormal; 3 ring shadow deformation can be oval or irregular shape; 4 side piece ring shadow position bias Pre- or posterior; 5 fetal bones overlap with the annulus after development. Combined with early pregnancy symptoms and signs, it is not difficult to make a diagnosis. People to check: Women who have used IUDs. Precautions Contraindications before examination: The examination should be 3-7 days after the menstruation is clean. Requirements for inspection: Obey the doctor's instructions to check. Don't have to panic on the X line. When the patient is on X-ray examination, the safe exposure should be within 100 roentgens, and the allowable number of exposures and time should be determined according to the exposure amount. Inspection process Generally, the use of standing perspective and the application of TV perspective make the X-ray inspection of the IUD very convenient and clear. Fluoroscopy, need to reduce the aperture to observe carefully, in case of obesity, you must pressurize the lower abdomen, so that a part of the fat tissue can be seen. The lying position is easier to see than the standing position, because the lower abdomen is flat when lying, which is good for observation. If there is suspicious should be observed.
