    Abstract:
    The aim of this study was to evaluate the efficacy of endometrial cytology using the Uterobrush in the collection of samples for the diagnosis of endometrial lesions. The preparation technique for endometrial brushing specimens was also demonstrated. In their earlier study, the authors described the cyto-architectural criteria that appear to be more useful for the cytological assessment of endometrial lesions. Therefore, for the application of the diagnostic criteria, endometrial cytological sampling will become more important. With regard to the cell sample collection, the authors used the Uterobrush because the insertion into the uterine cavity is easy and painless. The authors compared the Uterobrush with the Endocyte, since they thought that cell clumps using the former device tended to be smaller. The purpose of the current study was to improve and evaluate cell preparation methods using the Uterobrush. The authors investigated three methods [i.e., conventional and improved techniques ("flicked" method) with the Uterobrush and the Endocyte] of endometrial cell collection and preparation. Using conventional methods, a brush was rolled along a glass slide and the collected material spread and smeared. However, using the "flicked" method, a brush is strongly flicked with forceps, so that the cells are transferred to the slide and its position is moved along the slide little by little and smeared. The frequency by size of cell clumps with tube or sheet-shaped pattern was examined in the preparations. Cell block specimens with the Uterobrush were also investigated. Endometrial cytology from a total of 90 women was evaluated. Most were outpatients and all were older than 20 yr (ranging from 20 to 54, average 42.7 yr). Of these, 30 cases from each group were examined by three methods. Uterobrush samples prepared by the "flicked" method have a greater quantity of cell clumps than those using the Endocyte sampler, while the frequency-by-size of cell clumps was by degree the same as the Endocyte. The cell clumps obtained in the Uterobrush "flicked" method preparation was considered equivalent or superior as an aid to making a diagnosis of endometrial lesions and it became obvious that the same criteria were applicable to both of instruments. Our cytological examination may be a potent aid to making a diagnosis of endometrial lesions and these findings will be helpful in the standardization of criteria in direct intrauterine cell samples.
