Transvaginal versus transabdominal ultrasonography in the evaluation of induced ovulation and its complications

ABSTRACT

The aim of this work was to evaluate the efficiency of TVS as compared to TAS in the monitoring of induced ovulation. The study included 35 patients undergoing hormonal therapy using hCG to induce ovulation. Each patient was examined at least four times during the menstrual cycle using both modalities. There was better correlation between the results of TVS and the estimated serum estradiol level in the study of five cases. In two cases TVS failed to show one or both ovaries, while TAS could do that. In conclusion, except in few cases, TVS is superior to TAS in the detection of the number, size and sharpness of the follicles during monitoring of induced ovulation specially in obese patients and in those with history of pelvic surgery and/or failed previous induction of ovulation. It avoids a full urinary bladder, an irritating request for both the patient and the radiologist, reduces the patient's discomfort at the time of the examination
