[Vaginal sonographic imaging of the ovula Nabothi].

Twenty patients, showing retention cysts in vaginosonographic examination, were included in our study. We differentiated between superficial and deep located Nabothian cysts. Fourteen cases showed primarily visible superficial cysts, the other six could only be detected vaginosonographically. The Nabothian cysts varied in size from 4 to 26 mm, the average diameter was 13 mm. Only four cases showed solitary Nabothian cysts, the other sixteen cases were multiple. The clinical significance of Nabothian cysts in the field of sterility diagnostics, especially the deep located retention cysts, cannot be assessed at present.
