A total of 43 infertile patients with hysterosalpingographic diagnosis of bifid uterus underwent sonography and subsequent laparoscopy/hysteroscopy to evaluate the capacity of ultrasound to demonstrate the peritoneal profile of the malformed uteri correctly. Sonographic visualization was adequate in 39 cases (90.7%) and the following were identified correctly: 1 of 2 didelphic uteri, all of 11 bicornuate uteri, all of 4 complete septate uteri, and all of 22 partial septate uteri. The sensitivity of ultrasound in detecting the presence of a perimetrial fundal notch was 92.3% and its specificity 100%. Thus, a precise differential diagnosis of 'double' uteri was possible with this technique, which may in some clinical situations provide an alternative to laparoscopy.
