[Urodynamic evaluations after abdomino-perineal resection of the rectum (author's transl)]

An uro-dynamic evaluation has been performed on 25 patients, who had been submitted to abdomino-perineal amputation of the rectum and had thereafter shown functional disturbances of micturition. On the latter, causes and mechanisms are discussed, particularly neurological as well as mechanical and inflammatory ones, with regard to their relationship with sex and other possible aspects in the field of pathology. In 16 cases urinary retention developed, in 4 cases urinary incontinence, in 4 cases urgency but complete voiding. The authors conclude by stressing the role of pre-operative uro-dynamic assessment in every patient who is going to be submitted to rectal exeresis, in order to detect sub-clinical functional impairment of micturition, which could be suitably treated, during the main operation itself, by either desobstructive or reconstructive measures.
