The real value of vaginal sonography in the early diagnosis of ectopic pregnancy was assessed in 12 cases where ectopic pregnancy was suspected by clinical evolution and levels of B-HCG, and subsequently confirmed by microlaparotomy. The results were compared with those obtained with abdominal sonography and values of B-HCG. Vaginal sonography gave no false negatives and the percentage of false positives was 16.6%. The most typical echographyc images were: 1. Adnexal Mass (50%), 2. Pseudoring (42%), 3. Yolk sac &/or Embryo &/or Heart rate (25%). Values of B-HCG greater than 600 mIU/IS without embryo from 35th day are highly suspicious with regard to ectopic pregnancy.

Based on three cases of foetal abnormalities (hydrocephalus, prune-belly syndrome, and unilateral multicystic renal disease) diagnosed and treated by intrauterine sonographic control, the article describes the technique, evolution and outcome of these cases. Two patients (the hydrocephalus and the prune-belly syndrome) died after delivery, whereas the third one lives in normal conditions. The different diagnoses and prognoses of this new surgical procedure are discussed. We think that hydrocephaly and renal obstruction have a very bad prognosis when diagnosis and therapy are not performed an initiated at an early stage. Unilateral disease of Potter-Syndrome is associated with a very good prognosis irrespective of whether therapeutic intervention is effected or not. For this reason, the intervention should be considered according to the compressive action that the cystic renal disease can exercise on the other kidney or lung.

In patients with cervical incompetence, the diagnostic efficiency of abdominal, perineal and vaginal sonography was compared. 73 patients, who were divided into three groups, were examined: Group A (n = 50) control group, Group B (n = 11) normal pregnancies, Group C (n = 12) pregnancies with demonstrated cervical incompetence. According to our results, using vaginal sonography, only the incompetent pregnancies showed significant shortening of the cervical length. Characteristic scans were also obtained (membrane herniation) which were useful in diagnosis and control in the performance of cerclage.
