Prospective cross-sectional study. OBJECTIVES: To investigate
residual urine volumes after intermittent catheterization (IC) in men with spinal
cord injury (SCI) and the effect of residual urine on the rate of symptomatic
urinary tract infections (UTIs). SETTING: Single SCI rehabilitation center in
Switzerland. METHODS: Sixty men experienced in IC (>/= 6 months) emptied their
bladder twice by IC. Immediately after catheterization, residual urine was
determined by ultrasonography. Personal characteristics and bladder diary details
(annual UTI rate, catheter type) were also collected. RESULTS: The median
residual urine volume was 7.0 ml (lower quartile (LQ): 0.0, upper quartile (UQ):
20.3 ml). No residual urine was observed after 42% (n=50) of all catheterizations
(n=120). Unsatisfactory residual volumes (that is, >50 ml) were observed after 9%
(n=11) of all catheterizations. There was no significant (P=0.95) difference
between the median residual urine volume of men with recurrent (>2 UTIs per year)
UTIs (2.5 ml, LQ: 0.0, UQ: 29.3 ml) and the volume of those with sporadic (</= 2
UTIs per year) UTIs (6.0 ml, LQ: 0.0, UQ: 20.0 ml). CONCLUSIONS: Bladder
evacuation by IC is an efficient method, resulting in zero or small residual
urine volumes. The small residual urine volumes generally observed after IC do
not predispose for UTIs.
