BACKGROUND: Ipsilateral deviation of the uterus (IDU) has been suggested to be specific for torsion. OBJECTIVE: To investigate the sensitivity and specificity of IDU in diagnosing torsion. MATERIALS AND METHODS: We retrospectively reviewed the pelvic US examinations in girls performed at Nationwide Children's Hospital in 2007 and compared the uterine position in girls with a normal US scan (group 1) or with adnexal masses (group 2) with the uterine position in girls with torsion (group 3). RESULTS: Uterine deviation was found in 7 of 297 girls (2%) in group 1 and in 6 of 47 (13%) in group 2, and was attributed to stool in the colon splaying the adnexa and uterus. In group 3, 18 of 44 girls (41%) had moderate or marked uterine deviation and none was associated with stool displacing the uterus. Uterine deviation was more common and severe in girls in group 3 than in girls in group 1 (P<0.001) and group 2 (P=0.010). The sensitivity and specificity of IDU for torsion were 41% and 98%, respectively. CONCLUSION: IDU is more common in adnexal torsion than in other causes of adnexal masses. With supporting clinical and imaging findings, IDU appears to be a specific marker for torsion.
