OBJECTIVE: This study evaluated the influence of different urination methods on the urinary systems of patients with spinal cord injury. METHODS: Patients with spinal cord injury were grouped according to their usual voiding method: clean intermittent catheterization (CIC); Crede manoeuvre/reflex voiding; indwelling catheterization; normal voiding. Urinary tract infections (UTIs) were monitored and type B-ultra-sonography (B-USG) scans, renal function tests and urodynamic studies were performed in all patients over a 2-year period. RESULTS: Compared with the normal voiding group (n = 14), incidence rates of UTIs were significantly different in the Crede manoeuvre/reflex voiding (n = 26) and indwelling catheterization (n = 12) groups but not in the CIC group (n = 15). All intervention groups had a significantly higher rate of positive findings on B-USG scan and a significantly increased residual urine volume, compared with the normal voiding group. In addition, residual urine volume was significantly lower in the CIC group compared with the Crede manoeuvre/reflex voiding and indwelling catheterization groups. CONCLUSION: CIC was shown to be the optimal method for assisted bladder voiding after spinal cord injury.
