Hysterosalpingography (HSG), also known as uterosalpingography, [1] is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the fallopian tubes. It is a special x-ray procedure using dye to look at the womb ( uterus ) and fallopian tubes. [ 2 ]
Speculum used in standard vaginal procedures. Cusco's speculum: Bivalved self retaining speculum. Its advantage over Sim's speculum is that no assistance is required to hold it in place. Hence, minor procedures like papsmear, IUCD insertions can be performed independently. Its disadvantage is the limited visualization of vagina walls.
In one 2007 prospective study, the mean time for procedure was 6.8 minutes (range = 5–18 minutes) [24] for a trained physician to perform. The procedure can be performed in a physician's office. [citation needed] The procedure is reported to be permanent and not reversible by the manufacturer. Nevertheless, several Essure reversals have been ...
However, a small hydrosalpinx may be missed by sonography. During an infertility work-up a hysterosalpingogram, an X-ray procedure that uses a contrast agent to image the fallopian tubes, shows the retort-like shape of the distended tubes and the absence of spillage of the dye into the peritoneum. If, however, there is a tubal occlusion at the ...
Falloposcopy (occasionally also falloscopy [1]) is the inspection of the fallopian tubes through a micro- endoscope. [2] The falloposcope is inserted into the tube through its opening in the uterus at the proximal tubal opening via the uterotubal junction; technically it could also be inserted at the time of abdominal surgery or laparoscopy via the distal fimbriated end.
A HSG is performed after menses and before ovulation during the first half of a menstrual cycle. It is not performed if the patient is pregnant, has a pelvic infection, or heavy bleeding at the time of the test. [17] The procedure usually takes 30 minutes and often takes place in an outpatient setting such as a hospital or clinic.
Further, using fluoroscopy or hysteroscopy proximal tubal occlusion can be overcome by unilateral or bilateral selective tubal cannulation, a procedure where a thin catheter is advanced through the proximal portion of the fallopian tube os to examine and possibly restore tubal patency [8] salpinostomy (creating an opening for the tube) [9] or ...
Historically Lipiodol was often used as a contrast medium at hysterosalpingography (HSG: a procedure to determine tubal patency [i.e. whether the fallopian tubes are open], used in the investigation of subfertility). It became less commonly utilized in the 1960s to 1980s because the more modern water-soluble media give images that are easier to ...
