Transvaginal hysterosonographic evaluation of septate uteri: a preliminary report.

The objective of this study was to evaluate the diagnostic value of hysterosonography in septate uterine congenital abnormalities and more particularly in septate uteri. A total of 14 patients with a history of repeated spontaneous abortion or infertility who had previously undergone hysterosalpingography were included in this study. Patients were first examined by standard transvaginal ultrasound. Hysterosonography was then carried out by the intrauterine injection of an isotonic saline solution. The septate uteri were diagnosed by hysterosonography in all 14 patients (100%). Hysterosonography permitted the measurement of the thickness and height of the septum. Hysterosonography and transvaginal ultrasound enabled the correct diagnosis of malformation type in eight cases (57%). The accuracy of hysterosonography in postoperative control was greater than that of hysteroscopy. Transvaginal hysterosonography with saline solution is a low-cost, easy and helpful examination method for septate uteri. We propose that hysterosonography should be performed for the primary investigation of infertility and repeated miscarriages.
