Abstract
Objectives: We conducted a pilot study in 20 women with sonographically suspect endometria, to assess the value of contrast sonography and patient acceptance of this procedure. Methods: Saline solution 4–20 ml was injected into the uterine cavity using an embryo transfer catheter, followed by hysteroscopy in 19 cases and hysterectomy in one case. Results: A polyp was diagnosed in 12 patients, a submucous myoma in one patient, a proliferated endometrium in five patients and a placental polyp in one patient. A sonographic irregular structure was diagnosed in one patient which turned out to be coagula on hysteroscopy and histology. The procedure was well accepted by all patients. The diagnosis found by contrast sonography agreed in all cases with that found by hysteroscopy. Conclusion: Our results show that contrast sonography is an easy, quick and inexpensive procedure which increases the diagnostic value of vaginal sonography. The indications for contrast sonography are based on inconclusive sonographic findings, especially if polyps or submucous myoma are suspected.
