Transabdominal sonography comparison with transvaginal sonography

Abstract

Aims & Objectives: Transvaginal sonography (TVS) comparison with trans-abdominal sonography (TAS) in the diagnosis of pelvic masses Study Design: Retrospective descriptive study conducted at Gynae clinic Jinnah Hospital Lahore with collaboration of radiology department Materials and Methods: Transvaginal Sonogram was compared with transabdominal sonogram in hundred women referred for evaluation of pelvic masses from gynae clinic. All the women were interviewed regarding their age, parity, duration of mass and associated symptoms. Diagnosis was based on the combination of clinical, sonographic (TVS, TAS) and surgical correlation. Both ultrasound modalities were compared for the details about the internal architecture and diagnostic information. Results: Most common age group with pelvic masses was between 26-35yrs. TVS was more sensitive for both uterine and adnexal masses. Sensitivity of TAS was 65% and TVS was 88%. There was a significant difference in diagnosing true positive cases by trans-vaginal approach. (P value < 0.001) Specificity of TAS was 89% and TVS 86% for both uterine and adnexal masses. Image quality was better in 87% of cases with trans-vaginal approach and 5% of cases with trans-abdominal approach and it was equivalent in 8% of cases. There was a significant difference in the image quality between two modalities (P value < 0.001). Regarding anatomical details TAS was better in 12% of cases and TVS was better in 28% of cases and both were equivalent in 60% of cases, Diagnostic information of these two modalities was almost equivalent. TAS was better in 7% of cases and TVS was better in 8% of cases and both were equivalent in 85% of cases Conclusion: The results suggest that TVS has considerable advantage over conventional TAS in evaluation of pelvic masses in women.
