Aim: The primary goal of urologic management in children with neurogenic bladder is to reduce the risk of urinary tract infection (UTI) and associated renal injury. We aimed to evaluate the use of antibacterial-coated clean intermittent catheterization (CIC) catheters for neurogenic bladder patients in comparison with standard catheters. Material and Methods: We performed a retrospective study of 144 neurogenic bladder patients aged 6-16 years old, who received CIC at two major centers between January 2007 and June 2016. Group 1 consisted of children used antibacterial coated (chitosan) catheter (n=55), group 2 of children used standard CIC without antibacterial (n=42) and group 3 of children used standard CIC returned into antibiotic coated CIC mimimum 6 months (n=29). Febrile urinary tract infection and asymptomatic bacteriuria were evaluated among patients with antibacterial coated or standard catheters. We also focused on a subgroup of patients with high risk of urinary tract infection (grade 3> vesicoureteral reflux, previously scar formation in renal scintigraphy). Results: Totally 126 patients (89 female, 37 male) were involved in this study. The mean age of the study group was 9.6±2.6 years (range 6 to 16) and the mean follow-up 58±14 months (min: 22, max: 69). There was no significant difference between three groups for asymptomatic bacteriuria and febrile UTI frequencies. However, febrile UTI frequencies and de nova scar formation in renal scintigraphy were higher in previously defined subgroup of patients with high risk of urinary tract infection in group 2 than group1 and 3. Discussion: Both antibiotic coated and standard CIC can be used in children with neurogenic bladder with similar complication rates. Patients with high risk of urinary tract infection (higher than grade 3 vesicoureteral reflux, dilated ureter, previously de nova scar formation in renal scintigraphy) will benefit from antibacterial-coated catheters rather than standard ones.
