Taking care of urine and stool passage in patients with complete spinal cord lesion

Bladder atonia and areflexia are functional consequences of spinal shock following SCI. Sphincters are inactive, voiding is not possible. The bladder is distended. During this acute phase the therapeutic aim occurs in ensuring of the urine derivation preventing complications. Following procedures are used: permanent indwelling catheter, suprapubic drainage, intermittent cathe terization, reflex voiding by bladder tapping and suprapubic manual pressure. First days after injury on the ICU, a permanent indwelling catheter is used, later on changed to suprapubic drainage. It is recommended to change to intermittent catheterization as early as possible. Related to the level of injury the catheterization by themselves is trained for. Presence of urine infection can influence these algorithms. An adequate therapy of urine infection prevents bladder stone formation. Basic diagnostic for detrusor-sphincter dyssynergy during the chronically phase is the video-urodynamical assessment. Therapy is difficult, it occurs in a sufficient derivation. Pharmacological therapy mainly is focused to reduce the hydrostatic pressure in the urine system. Beside suprapubic epicystostomy surgical procedures are described. Those procedures support continence or provide for permanent incontinence (urinal).
