Etiology. Distinguish making factors and contributing conditions of abaissement. To making factors carry rising intraabdominal pressure (a physical strain, fixing labors, persistent constipations and profuse diarrheas), traumatic and dystrophic lesions of muscular aponeurotic formations of a diaphragm of a basin and the copular apparatus of a rectum.
