[Ultrasono-hysterography: techniques and indications].

Sonohysterography consists in injecting a saline solution into the uterine cavity and performing transvaginal sonography. The purpose of this procedure is the pre-operative assessment of intracavitary anomalies, especially polyps, myoma, adhesions, congenital abnormalities such as septate uterus. Technical aspects are shown. This procedure is painless, atraumatic and no adverse effect is seen if the usual precautions before hysterography are taken. The right place of this exam is between hysterography and hysteroscopy, but more widespread use is required before a final opinion can be reached.
