Objective : To assess the diagnostic accuracy of transvaginal sonohysterography
in the detection of uterine cavitary abnormalities in patients
with recurrent abortion.
Study Dysign : A total of 117 patients with at least two consecutive
abortions were enrolled in a prospective case-controlled study. Patients
underwent transvaginal ultrasonography, saline-contrast transvaginal
sonohysterography and hysterosalpingography for the evaluation of the
uterine cavity. The results of the three techniques were compared with
those revealed by hysteroscopy. Suspected uterine anomalies were confirmed
by laparoscopy.
Results : Thirty-nine patients ( 33.3 % ) demonstrated uterine cavitary
lesions. Sonohysterography was found to be highly sensitive
(100%) and specificity (100%) in screening the uterine cavity based on
hysteroscopic confirmation. Transvaginal ultrasonography and hysterosalpingography
had lower sensitivity (41.0 % and 74.4 %, respectively)
and so were able to detect 13.7% and 27.3 % of uterine pathologies
respectively. Sonohysterography, also, properly defined the size and location
of any uterine outgrowths. No patient required preprocedural
analgesia nor antibiotics and none had postprocedural pelvic infection.
Conclusion: Sonohysterography represents an easy, noninvasive, tolerable
and highly sensitive method for the diagnosis of uterine cavitary
abnormalities in patients with recurrent abortion.
