This study was designed as a comparative cross-sectional cross-over trial on children performing clean intermittent catheterization (CIC) with reused catheters for 1 or 3 weeks.


To determine the incidence of symptomatic urinary tract infection (UTI) and bacteriuria (defined as colony count of ⩾105 colony forming units per ml of a single strain of organism) in these two different frequencies of catheter change.


Multidisciplinary children's neurogenic bladder clinics at two tertiary care hospitals in Kuala Lumpur Malaysia.


Forty children aged between 2 and 16 years performing CIC for at last 3 years were recruited. Medical and social data were obtained from case files. Baseline urine cultures were taken. All children changed CIC catheters once in 3 week for the first 9 weeks followed by once a week for the next 9 weeks. Three-weekly urine cultures were obtained throughout the study. Standardization of specimen collection, retrieval and culture was ensured between the two centers.


At baseline, 65% of children had bacteriuria. This prevalence rose to 74% during the 3-weekly catheter change and dropped to 34% during the weekly catheter change (Z-score 6.218; P<0.001). Persistence of bacteriuria (all three specimens in each 9-week period) changed significantly from 60 to 12.5%, respectively (P<0.005). There was no episode of UTI during the 18-week study period.


Reuse of CIC catheters for up to 3 weeks in children with neurogenic bladders appears to increase the prevalence of bacteriuria but does not increase the incidence of symptomatic UTI.
