Urologic aspects of traumatic central cord syndrome.

Abstract

Central cord syndrome (CCS) is a subset of spinal cord injury, characterized by more motor involvement of the upper extremities than the lower extremities and sacral sensory sparing. Patients with central cord syndrome have been reported to have a good rehabilitation and urologic outcome. Our purpose was to assess the urologic outcome in a group of patients with central cord syndrome. We reviewed 23 patients with central cord syndrome who were admitted to Hines VA Hospital between 1983 and 1991, 20 of whom were older than 50 years of age. Urodynamic studies showed detrusor hyperreflexia with a synergistic EMG in 15 patients and detrusor hyperreflexia with external urethral sphincter dyssynergia (DSD) in five patients. Three patients with no urologic problems were not tested. Bladder sensation was preserved during filling in all patients. At follow-up (median = 2-4 months), 16 patients (70 percent) were voiding, seven of whom required either occasional external or intermittent catheterization; nine were voiding independently. The seven other patients (30 percent) required either continuous external or intermittent catheterization (including the five with DSD). Urologic morbidity in the period after SCI included: urinary tract infections (12), renal (2) and bladder calculi (2), superficial bladder cancer (1), epididymitis (1) and none (6). Fifteen patients (65 percent) were ambulatory at follow-up while four patients needed wheelchairs. Data were not available for the other four patients. Urodynamic studies in three of the wheelchair-bound patients showed that two of them had DSD. Most patients with central cord syndrome have favorable urologic and rehabilitation outcomes and can be managed conservatively.(ABSTRACT TRUNCATED AT 250 WORDS)
