Trans abdominal versus transvaginal ultrasound in assessment of polycystic ovary.

Abstract

Objective: The main objective of our study is to compare transabdominal and transvaginal ultrasound in assessment of polycystic ovaries. Study Design: Cross Sectional Comparative study. Setting: Jinnah Medical College and Hospital Karachi. Period: January 2016 to January 2017. Material & Methods: 200 married females were selected with complaints of irregular menses, hirsutism, obesity and infertility and age group 18-45 years. Patients with already diagnosed polycystic ovaries or on hormonal treatment were excluded. Results: Out of 200 patients, 54 patient shows poly cystic ovaries both on trans abdominal and Trans vaginal ultrasound, 16 patients on Trans vaginal ultrasound only  but not on trans abdominal ultrasound in which 13 patients were very obese. Rest of the patients had normal ovaries on both types of ultrasound examinations. The prevalence of polycystic ovaries noted by transabdominal ultrasound is 27% (54/200) overall and by TVS ultrasound is 35% (70/200). Conclusion: PCOS is quite a common endocrine complaint. Our results suggest that prevalence of PCO is 27% by trans-abdominal u/s and 35% by TVS. The Mean volume of ovary is greater in women with polycystic ovaries but there is no significant difference seen in prevalence of polycystic ovaries diagnosed by both ultrasound examinations. Although it has been observed that TVS is better than transabdominal U/S in detection of PCO but our study shows that the two methods are almost analogous except in obese patient where TVS displayed better results.
