Patient's question:
Detailed medical condition and consultation purpose: I have polycystic ovary syndrome (PCOS), and the doctor has recommended a fallopian tube hydrotubation. How is fallopian tube hydrotubation performed? Is it complicated? Does ovulation indicate that the fallopian tubes are unobstructed?Doctor's answer:
Hysterosalpingography (HSG) is a diagnostic procedure where a syringe (containing normal saline and antibiotics) is used along with a cervical cannula to slowly inject saline into the uterus. The assessment of whether the fallopian tubes are open or partially blocked is based on the presence or degree of pressure exerted by the saline. Why can some women get pregnant after this procedure? Scholars explain that the pressure from the water helps to straighten twisted fallopian tubes or clears blockages caused by inflammation, such as adhesions or obstructions in the fallopian tube lumen. However, those who conceive successfully after this method are the lucky few, as they represent only a small percentage of women who undergo the procedure. In reality, before the procedure, doctors cannot determine whether the patient has twisted fallopian tubes or adhesions/blockages in the fallopian tube lumen, making the process highly subjective and accidental. Clinically, it has also been observed that infertile women with confirmed bilateral fallopian tube blockages, even after being cleared with the procedure, still fail to conceive.Although hysterosalpingography is a minor surgical procedure, it requires high precision. Providing women who are not pregnant with a rough understanding of this knowledge may help them choose the right hospital for treatment and foster cooperation with their doctors, ensuring the procedure is used appropriately, improving the reliability of the evaluation, and guaranteeing safety.
Ovulation and fallopian tube patency are unrelated.
