In 19 patients the transvaginal (TVU) and in 24 patients the transabdominal (TAU) ultrasound approaches were compared in their ability to identify by visualisation the adnexal mass of ectopic pregnancy. The direct visualisation of ectopic pregnancy (EUP) was 25% in TAU and 94.7% in TVU approach (p less than 0.03). All women had a proven EUP in laparoscopy. TAU approach showed a significant inferiority (p less than 0.02) and TVU a significant superiority (p less than 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%. Line formed endometrium was seen in 6.9%, in 37.2% the thickness of endometrium was under 10 mm, in 55.8% more than 10 mm. An intrauterine pseudo-gestation sac was detected in 6.9%, corpus luteum formation in 37.2%. With vaginosonography organs can be seen at close range, therefore it is easier to recognise the specific signs of EUP - an extrauterine ring - formation surrounded by a dam-like structure of the tube.
对19例患者采用经阴道超声（TVU）、24例患者采用经腹超声（TAU），比较二者可视化识别异位妊娠附件包块的能力。经腹超声对异位妊娠（EUP）的直接可视化率为25%，经阴道超声为94.7%（p<0.03）。所有女性均经腹腔镜证实为异位妊娠。与触诊相比，经腹超声显示出明显劣势（p<0.02），经阴道超声则显示出明显优势（p<0.08）。43例女性中有83%出现点滴出血。20.9%可见异位妊娠的非特异性征象，如子宫直肠窝积液。6.9%可见线状子宫内膜，37.2%子宫内膜厚度小于10mm，55.8%大于10mm。6.9%检测到宫内假妊娠囊，37.2%有黄体形成。经阴道超声检查可近距离观察器官，因此更容易识别异位妊娠的特异性征象——宫外环状结构，其周围有输卵管的堤坝样结构。
