Patient's question:
I want to ask how tubal contrast is done. It can be done three days after the menstrual period is clean. I want to know what the process is like and whether it hurts or not? Please share your experiences with those who have had it done.Doctor's answer:
Hello: Hysterosalpingography (HSG) is an examination method that involves injecting a contrast agent through the cervix to visualize the uterine and fallopian tubes. The contrast agent is typically 40% iodized oil or an organic iodine preparation. The contrast agent is injected under fluoroscopy, and after the uterus and fallopian tubes are sufficiently visualized, images are taken. Repeated imaging is required at intervals (one day for iodized oil) to observe the patency of the fallopian tubes. Occasionally, HSG can restore the patency of blocked fallopian tubes, achieving a therapeutic goal.Indications: Seeking the cause of infertility; reproductive organ malformations and their types; exploring the cause of uterine bleeding; understanding fallopian tube blockage after various sterilization methods; identifying the cause of reduced or absent menstruation; determining the position of an intrauterine device (IUD) and its relationship with the uterus; assessing uterine conditions before in vitro fertilization (IVF).
Contraindications: Acute or subacute inflammation of the reproductive organs or active tuberculosis; systemic infection or severe illness; menstruation; within 6 weeks of normal delivery, miscarriage, or suction curettage; potential pregnancy; uterine malignancies; iodine allergy.
Preoperative Preparation: The best time for the examination is 3 to 7 days after the end of menstruation; the patient should be provided with as detailed information as possible about precautions and potential complications to alleviate anxiety, and instructed to sign the informed consent form; constipated patients should take a laxative the evening before the examination or undergo an enema 2 hours before to clear intestinal contents for clearer imaging; the patient should void before the examination to avoid affecting uterine position; an iodine allergy test should be performed before the examination, and only if no allergy is present should the examination proceed.
