Non-Invasive Laboratory Investigations
1. Hysterosalpingography (HSG) / Dye Push:
This is a procedure where contrast media is pushed inside the uterine cavity through the cervical canal, by a canula in the radiology department. It is performed within 10 days of the menstrual cycle, but after the period stops, HSG helps to delineate the uterine cavity and to find out the patency of the fallopian tubes. We in our clinic do not go by the printed report of radiologists. We analyze the HSG plate thoroughy and try to find out patency through the nature of spill or dye, length of the tube, whether any coiling or kinking is there, and the tubo-ovarian relation (TOR), if possible.
2. Sonosalpingography (SSG):
This is another less invasive procedure, to test the tubal patency. Here, normal saline is passed through the uterine cavity through a baby catheter. When the water comes out through the abdominal opening of fallopian tube, it falls on the pelvic cavity, which can be detected through ultrasonography. According to our view, interpretation of this test is difficult and injection of excess amount of fluid which may be necessary anytime, causes excessive pain.
3. Hydrotubation / Water Injection:
This is a non–invasive procedure where 5–10 ml medicated solution is pushed inside the uterine cavity through a canula, without anesthesia. This is a clinic procedure, performed during the first half of the menstrual cycle (from D6-D10) to assess, maintain or sometimes to remove any minor obstruction/block in the fallopian tubes. It takes about 5-10 minutes and prophylactic antibiotics are usually given orally. Many authorities opine that hydrotubation is obsolete now-a-days.
Colposcopy is a procedure to observe neck of the womb (cervix), to find any or abnormality. This test helps to detect any pre-cancerous or cancerous lesions in the neck of the womb.
