Tubal imaging can also be inaccurate and another imaging test will be needed if necessary.
Tubography is a common method to check the patency of the fallopian tubes and should be performed by a specialized doctor. 3-7 days after the clean menstruation is the best time to do tubal imaging, 3 days before the operation prohibit coitus, before the operation also exclude acute reproductive tract infection and other contraindications.
Tubal spasm and low dosage of contrast medium may cause errors in the test results.
1. Tubal spasm: Failure to exhaust the air in the cervical catheter before injecting the tubal contrast agent, too fast and too much force when injecting, as well as low temperature of the contrast agent may cause tubal spasm, which will affect the entry of the drug into the tubes, thus leading to inaccurate test results.
2. Too little contrast medium: when the amount of contrast medium injected is too little to flow into the uterine cavity, it may lead to the tubes not being visualized, thus resulting in misdiagnosis.
If necessary, tubal imaging can be carried out again, after the imaging should prohibit pelvic bathing and sexual life for 2 weeks, but also follow the doctor’s instructions to take metronidazole and other antibiotics, in order to prevent infection.
