Application of 3D-HyCoSy in the diagnosis of oviduct obstruction.

Abstract

The aim of the study was to analyze the application value of three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in the diagnosis of oviduct obstruction. Fifty-two patients with infertility and oviduct obstruction were continuously selected and treated with 3D-HyCoSy and CLP (CLP). It was found that according to CLP diagnosis, 40 oviducts were obstructed, 30 were partially obstructed, 12 were tortuous and 22 were completely obstructed. The 40 cases were unilaterally pathological, 24 were bilaterally pathological, 10 were diagnosed as congenital dysplasia, 35 were diagnosed as inflammation and 19 were diagnosed as tumor and cyst. Based on the diagnostic criteria of CLP, the diagnostic sensitivity, specificity, positive predictive values and negative predictive values of 3D-HyCoSy was 82.4, 88.3, 77.9 and 90.2%, respectively. The contrast agent flow time of oviduct obstruction (tortuosity and complete obstruction) as diagnosed by 3D-HyCoSy was significantly prolonged when compared with that of partial oviduct obstruction (P<0.05), and flow time of inflammation as diagnosed thereby was longer than that of congenital dysplasia, tumor and cyst. Following the diagnosis of inflammation, the shape of the contrast agent was tenuous, swollen, angled, rigid and distorted and the occurrence rate of inflammation was significantly higher (P<0.05). In conclusion, the diagnostic effect of 3D-HyCoSy on oviduct obstruction was more accurate and can show different features when diagnosing different types of inflammation, thus having a certain value for identifying the inflammation.
