Sonohysterogram (SHG)A Saline Ultrasound for the Diagnosis of Uterine Abnormalities
The sonohysterogram is a sonogram performed after a saline injection.
The sonohysterogram is completed after menstruation has ended and before ovulation occurs. The timing of the procedure allows for optimal viewing of the uterine walls, since they are at their thinnest at this point in a woman’s cycle. The patient will often call the doctor’s office on the first day of her cycle to schedule the appointment. Purpose of the SHGThe sonohysterogram allows the doctor to evaluate the uterus for the causes of
The saline ultrasound may also be used as a pre- or post- operative surgery evaluation and for other evaluation purposes. Preparing for the Saline UltrasoundIt is important that the patient is not pregnant or suffering an active infection during the saline ultrasound. The doctor may require the patient to be tested for pregnancy and/or infection prior to the exam. Some doctors also prescribe a round of antibiotics to be taken in the week before the test to prevent infection. Due to cramping caused by the SHG, the doctor may suggest a full dose of over-the-counter pain medication to be taken just prior to the procedure.

The saline helps to highlight the uterus and any irregularities within it, including structural abnormalities, fibroids, polyps and scar tissue. Many of these problems can be surgically corrected.

RisksCramping and spotting after the sonohysterogram are common, and the patient should not be concerned if she experiences these symptoms. However, infection is a slight possibility. According to the American Society for Reproductive Medicine, infection occurs in 1% of patients after undergoing sonohysterogram, and patients with tubal disease may have an increased risk. The patient should notify her doctor, in the days following the procedure, if she has:
