sono-hystergram
A sono-hysterogram (SHG) is a variation on vaginal ultrasound but involves a saline infusion into the uterus (womb). The procedure can determine if a woman’s uterus is normally shaped.
reason for the examination
A sonohysterogram is carried out in the first instance to provide an image of the shape of the uterus to identify possible abnormalities. If there is uncertainty regarding the condition of the interior of the uterus (for example, if there is a suspicion of uterine polyps) as a result of standard vaginal ultrasound, a SHG will provide supplementary information. Sometimes, it will also be possible to see whether the fallopian tubes appear to be open. However, if there is a suspicion of tube problems, then a hysterosalpingography (HSG) is generally much better in assessing the situation. A sonohysterogram is not carried out as a standard procedure in every clinic. The most common method of examining the interior of the uterus is the hysteroscopy.
the examination
The procedure takes place in a clinic, generally during the first week following the last day of the menstrual period. Firstly, a catheter (a flexible tube) is inserted through the cervix, and then the probe of the vaginal echo is placed in the vagina. Next, a salt-solution is injected into the uterus, which assists the doctor in seeing the outline of the uterus. Some women complain of mild to moderate cramps.
