[Perineal topometry of male newborn infants in the surgical treatment of anal and rectal defects].

The aim of this work was to designate the place of the anus on the perineum with topometric method. The examinations were carried out on 100 healthy male newborns, born in time. Five basic diameters of perineum were determined: anal-symphyseal distance, anal-phallic, anal-scrotal distance, anal-coccygeal distance and transversal dimension of perineum. The material was examined taking into consideration body weight, body length and weight-growth index. Dimensions of perineum most useful to pointing out the location of the anus in case of impotency are: anal-coccygeal distance and anal-scrotal distance. The above dimensions show the greatest relation to male newborns weight.
