Hysterosalpingogram (HSG)
A hysterosalpingogram (HSG) is a radiographic procedure in which radiopaque contrast dye is injected through the cervix into the uterine cavity and fallopian tubes under fluoroscopic X-ray guidance.1 HSG provides a real-time image of uterine cavity shape and tubal patency. It detects structural uterine abnormalities including polyps, fibroids, intrauterine adhesions, and septal defects, as well as proximal or distal tubal obstruction. HSG has limitations: false-positive tubal occlusion results from tubal spasm occur, and peritoneal endometriosis or pelvic adhesions are not visible on HSG. In the RRM infertility evaluation, HSG is often an early step in the tubal assessment workup. It may be followed by diagnostic laparoscopy for definitive assessment of pelvic pathology. When proximal tubal obstruction is identified on HSG, clinicians may proceed to selective salpingography or transcervical catheterization of the fallopian tubes, a therapeutic extension of the diagnostic study that is a distinctive RRM/NaPro surgical technique.
