Genital prolapse is the weakening or loss of support of pelvic organs, accompanied by their descent or prolapse. There are many etiological reasons for developing this nosology. A form of the small pelvis may play a role in the development of genital prolapse. The study was carried out on 74 preparations of women's bone pelvis, 30 multidetector row spiral CT of small pelvis of patients with genital prolapse of III - IV degree. Standard and non-standard pelvimetric indices are estimated, on the basis of which a number of indices have been calculated, which make it possible to evaluate the shape of pelvis. According to the results obtained, in the anthropometric study of pelvic bone preparations, the most common forms were mesopelic, medium, uniform, harmonious and round forms of the pelvis. In this case, the cylindrical shape of the cavity of the small pelvis was most often encountered. According to the multidetector row spiral CT data, in women with genital prolapse, platypelic, low, broadened, broad and transversely oval bone pelvis forms were most common. The pelvis of women, suffering from genital prolapse, mainly had a dilating downward form of the small pelvis cavity.
