Diagnostic accuracy of sonohysterography vs hysteroscopy in benign uterine endocavitary findings

OBJECTIVE: To compare diag - nostic accuracy of sonohysterography vs hys - teroscopy in patients with benign uterine endo - cavitary findings. PATIENTS AND METHODS: This retrospec - tive study evaluated 202 patients submitted to sonohysterography after transvaginal ultra - sound examination suspicious for uterine en - docavitary findings. Cytological sample was taken and analyzed from the fluid used to dis - tend the uterine cavity. Of 202 patients enrolled for this study, 86 patients underwent gynaeco - logical surgery, of whom 77 were treated with operative hysteroscopy and 9 with other gynae - cological surgical techniques. Statistical analy - sis was performed to evaluate diagnostic agreement between sonohysterography vs hys - teroscopy and cytology vs histology. RESULTS: Diagnostic concordance between sonohysterography and hysteroscopy was sig - nificant (k value 0.87). The correlation between cytological and histological findings had a moderate level of concordance (k value 0.49). CONCLUSIONS: Sonohysterography pro - vides a diagnostic accuracy as well as hys - teroscopy, therefore, it could be considered an alternative procedure in the diagnosis of be - nign uterine endocavitary findings.
