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.
Menorrhagia remains a significant health issue for women worldwide. Traditionally hysterectomy has been the treatment of choice when excessive menstrual bleeding remains unresolved by hormonal manipulation. In an attempt to provide a less invasive alternative to hysterectomy, traditional techniques such as rollerball endometrial ablation were developed 20 years ago. Although extremely effective, they possessed the potential of significant intra-operative risks and their success depended on high technical proficiency of the surgeon. As surgery and technology evolved, second generation endometrial ablation devices were developed which demonstrated improved safety and efficacy rates that paralleled traditional treatments. Since 1997, the Food and Drug Administration (FDA) has approved five such devices for use in the United States. Each possesses a unique technology profile with supporting level I evidence that allows for the treatment of a wide variety of uterine anatomy.
This study aimed to determine whether the presence of endometrial polyps discovered during ovarian stimulation affects the outcomes of intracytoplasmic sperm injection (ICSI) cycles. This retrospective descriptive study was conducted in a private assisted reproductive technology unit. Medical records of ICSI cycles performed between January 2003 and December 2004 were reviewed. Patients were divided into three groups: patients with endometrial polyps discovered during ovarian stimulation (group 1, n=15), patients who underwent hysteroscopic polyp resection prior to their ICSI cycle (group 2, n=40) and patients without polyps (group 3, n=956). Main outcome measures were clinical pregnancy rates and implantation rates. Age of the patients, age of the husbands, body mass index, total amount of gonadotrophins used, length of stimulation, peak oestradiol concentrations, peak endometrial thickness and number of embryos replaced were not significantly different between the groups, nor were the pregnancy and implantation rates. Only one patient (12.5%) from the first group experienced miscarriage within 12 weeks of pregnancy. In conclusion, endometrial polyps discovered during ovarian stimulation do not negatively affect pregnancy and implantation outcomes in ICSI cycles.
