RESUMEN
To assess the diagnostic and accuracy of sonohysterography [SMG], hysterosalpingography [HSG] and transvaginal ultrasonography [TVU] in the detection of uterine cavity abnormalities in patients with recurrent pregnancy loss. Hysteroscopy was the gold standard. Subjects and methods: Forty five patients with recurrent pregnancy loss underwent TVU, SHG and HSG. The results of each examination were compared with those obtained by hysteroscopy. There was tolal agreement between hysteroscopy and SHG in detecting submucous myoma, uterine malformation and intrauterine adhesions while sensitivity rates of TVU for these lesions were 57.1%, 66.7%, and 0% respectively and 100% sensitivity rates. For intrauterine polyp detection SHG had higher sensitivity [75%] than TVU [25%] and both procedures had 10[3% specificity rates, I-ISO had 100% accuracy for detection of uterine malformation, low PPV [46.15%] for diagnosis of sub-mucous myoma and polyps and low PPV [66.7%], for intrauterine adhesion detection, SHG is a method of choice for the diagnosis of intrauterine pathology in habitual abortion patients
