SSG & HSG Procedure 

Sonosalpingography (SSG), also known as Sion test, is a diagnostic procedure primarily used for evaluating patency of fallopian tubes.[1][2] It was introduced as a screening procedure for infertility investigations.[3] It is becoming more popular among practitioners due to absence of side effects.[2] Under ultrasound scanning, a slow and deliberate injection of about 200 ml physiologic saline into the uterine cavity is accomplished via Foley catheter. An inflated bulb of the catheter prevents leakage of fluid outside uterine cavity. By visualizing the flow of saline along the tube and observing it as a shower at fimbrial end, tubal patency can be tested. Presence of free fluid in pouch of Douglas also confirms tubal patency. 

Hysterosalpingography (HSG), also known as uterosalpingography,[2] is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the fallopian tubes. This means it is a special x-ray using dye to look at the womb (uterus) and Fallopian tubes.[3] It injects a radio-opaque material into the cervical canal and usually fluoroscopy with image intensification. A normal result shows the filling of the uterine cavity and the bilateral filling of the fallopian tube with the injection material. To demonstrate tubal rupture, spillage of the material into the peritoneal cavity needs to be observed. It has vital role in treatment of infertility especially in case of fallopian tube blockade.
