Transvaginal scan and transabdominal sonogram pre and postoperative comparison

ABSTRACT

Transvaginal [TV] scan replaced transabdominal [TA] sonography in evaluation and scanning of certain conditions. TV and TA sonography were compared in a prospective study. A total of 88 patients [66 pelvic and 22 pregnancy] examinations were performed by two techniques at time, patients ranging in age from 14 to 60 years. The improved anatomic detail on TV scans yielded new information in 60 patients and better visualization of pelvic structures in 50 patients. Sonoclinical diagnosis was altered on the basis of TV sonographic findings in 75. Statistically comparison of the two techniques indicated that TV scanning was significantly better than TA scanning in the visualization of gestational sac content, detection of fetal heart motion, detection of twin in early pregnancy and evaluation of the endometrial canal in the retroverted or retroflexed uterus. TV scanning was significantly better than TA scanning in folliculometry, detection of ovarian mass or cyst especially with patients having leiomyomas obscuring the ovaries. Also, useful in detection of uterine small fibroids and cervical tumors staging
