Significance of asymptomatic bacteriuria in spinal cord injury patients on condom catheter.

A total of 56 male spinal cord injury patients on condom catheter drainage was studied prospectively within 6 months of the injuries for 5 years. Low bladder pressures (filling maximum 35 cm. water and voiding maximum 70 cm. water) were ascertained with video-urodynamics. External sphincterotomy was performed when necessary for detrusor-sphincter dyssynergia. Yearly upper tract imaging, serum creatinine levels and urine cultures were obtained. All patients had colonized urine (asymptomatic) during the entire study period. No patient sustained deterioration of the urinary tract on imaging or by serum creatinine determinations during the 5-year interval. We conclude that asymptomatic bacteriuria is of no consequence to the integrity of the upper urinary tract when low pressures are operant.
