Patient's question:
Hello doctor, I had a mycoplasma infection detected in November, and the doctor said my right fallopian tube was slightly thickened. Now the mycoplasma has turned negative. I would like to ask if I must undergo fallopian tube hydrotubation now? What related tests need to be done before the hydrotubation? How long does it take? Can hydrotubation definitely clear the fallopian tube? Can it be done in general second-class hospitals?Doctor's answer:
Hello: Hysterosalpingography (HSG) is one of the diagnostic methods for checking whether the fallopian tubes are unobstructed.Indications:
1. Suspected fallopian tube blockage in primary or secondary infertility;
2. To assess the outcome of tubal reconstructive surgery;
3. To examine and evaluate the effectiveness of various sterilization procedures;
4. To restore patency in mildly obstructed fallopian tubes.
Contraindications:
1. Presence of acute or subacute pelvic inflammation;
2. Severe cervical erosion or chronic cervical inflammation with purulent discharge;
3. Trichomonas vaginalis or Candida infection;
4. During menstruation or irregular vaginal bleeding;
5. Pregnancy;
6. Severe systemic diseases, such as heart disease or impaired lung function.
Timing Selection: The procedure is generally performed within one week after the end of menstruation. If done too early, the endometrium may not be fully healed or may still contain residual blood, which could lead to blood entering the abdominal cavity. If done too late, such as during the luteal phase, the endometrium is thicker, and using a metal catheter may easily damage it, causing the endometrium to be pushed into the abdominal cavity.
Procedure Steps:
Perform routine disinfection, wear sterile gloves, and drape a speculum. Insert the catheter tip into the cervical canal, connect the other end to a syringe, and slowly inject the fluid. Observe the resistance, backflow, and leakage. If all the fluid is injected smoothly without resistance or backflow, it indicates that the fallopian tubes are patent. If there is significant resistance, and the syringe returns 10ml of fluid when the pressure is released, the fallopian tubes are blocked. If there is moderate resistance with slight backflow, it suggests that the fallopian tubes are partially patent. Do not force the injection if resistance is encountered.
