[Hysteroscopic diagnosis and treatment of endometrial polyps]. 
The aim of the retrospective study was to analyse the frequency of polyps, anamnestic data and the result of histological examination overviewing 163 polyps which was find during 1900 hysteroscopy.  In the history of patients dilatation and curettage was find in 22% one time and in 6.6% two times, but the polyps were removed by hysteroscopy in the end.  The indication of hysteroscopy was haemorrhage in 55%, abnormal ultrasonographic results in 25% and sterility in 15%.  During 153 polypectomy were two perforations (0.89%), no other major complication.  The result of histological examination of 153 removed polyps was surprising, because in 22 cases proliferative endometrium, in 17 cases hyperplasia, in 6 cases secretory endometrium, in 5-5 cases fibroid and dyshormonal effect and in 1-1 case endometritis, adenomyosis, atrophy and malignant transformation was the histological diagnosis.  Despite of relatively high false positive hysteroscopic results, the endoscopic procedure is useful method for treatment of endometrial polyps if the aim is the minimal invasivity and organ saving surgery.
