Objective : To compare three-dimensional transvaginal sonography (3D-TYS) (non invasive) and hysteroscopy
(minimally invasive) as a diagnostic tool in patients suffering from abnormal uterine bleeding (AUB).
Design: A prospective randomized comparative study.
Setting: This study has been conducted in the Obstetrics and Gynecology department at Bab-AI Shaaria, Al-Azhar
University Hospitals - AI Azhar University, from March 2003 to May 2005.
Patients & Methods; One hundred and thirty patients complaining of abnormal uterine bleeding were investigated by
3D transvaginal ultrasound and hysteroscopy. Data obtained were recorded, correlated and statistically analyzed.
Results: Both hysteroscopy and 3D-TYS showed 100% sensitivity and specificity in diagnosing atrophic endometrium
and suspecting malignancy. However, in cases of hyperplasia, 3D-TVS had the same 100% sensitivity hut less
specificity than hysteroscopy. On the other hand, in cases of polyps 3D-TYS had less sensitivity and specificity than
hysteroscopy.
Conclusion: Both hysteroscopy (minimally invsasive) and 30-TYS have the same accuracy in diagnosing atrophic
endometrium and suspected malignancy, but Hysterescopy is superior than 3D-TYS in diagnosing hyperplasia and
polyps in patients suffering from AUB.
