[Early diagnosis of tubal pregnancy with vaginal sonography]

In 19 patients, the transvaginal (TVU) and in 24 patients, the transabdominal (TAU) ultrasound approaches were compared in their ability to identify by visualization the adnexal mass of ectopic pregnancy. The direct visualization of ectopic pregnancy (EUP) was 25% in TAU and 94.7% in TVU approach (p 0.03). All women had a proven EUP in laparoscopy. TAU approach showed a significant inferiority (p 0.02) and TVU a significant superiority (p 0.08) in comparison to palpation. 83% out of 43 women had spotting. Unspecific signs for EUP, like retrouterine fluid, was seen in 20.9%. Striated endometrium was seen in 6.9%, in 37.2% the thickness of endometrium was less than 10 mm, in 55.8% more than 10 mm. A pseudogestationsac was detected in 6.9%, corpus luteum formation in 27.2%. With vaginosonography, organs can be seen at close range, and the specific signs of EUP, an extrauterine ring-formation surrounded by a dam-like structure of the tube, was identified in 94.7%.
