Surgical treatment of the static perineal modifications in spinal cord or cauda equina lesions.

Severe dysuria, due to insufficiency of the perineal floor associated during micturition with a posterior tilting of the prostate-bladder block in lower or in associated upper and lower motor neuron lesions, can be treated surgically by a prostato cytso pexy. Since 1971, eight patients with post-traumatic conus and/or cauda equina lesions have been treated by this intervention. On the follow-up the satisfactory results appear to remain stable. An alternative surgical technique using the abdominal pyramidalis muscle is described so as to fix the prostate, associated with a bladder-pexy. The recurrence of dysuria, after the intervention, has always been caused by an additional lower urinary tract pathology. The comfort of the patients has been greatly improved.
