Transvaginal (TVU; 19 patients) and transabdominal ultrasound (TAU; 24 patients) were compared in their ability to visualize an ectopic pregnancy. The direct visualization of ectopic pregnancy (EUP) was 25% with TAU and 94.7% with TVU. All women had a proven EUP in laparoscopy. TAU approach showed a significant inferiority (P<0.02) and TVU a superiority (P<0.08) in comparison to clinical examination. 83% of 43 women had spotting. Nonspecific signs for EUP like fluid in the pouch of Douglas was seen in 20.9%. Thin 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 pseudogestation sac was detected in 6.9%, corpus luteum formation in 37.2%.
