Ureteral stents do not cause bacterial infections in children after ureteral reimplantation - Abstract

Department of Urology, University Hospitals, Leuven, Belgium.

To determine, in a prospective study, the incidence of bacterial colonization and the risk of bacterial infection of indwelling double-J stents in children undergoing ureteral reimplantation. In a balance between the safety and comfort of the child, the need for postoperative stenting of the reimplanted ureters has been discussed. It is unknown whether an indwelling double-J stent after ureteral reimplantation would be a risk factor for postoperative urinary tract infection.

From 2005 to 2010, 209 children (138 girls and 71 boys; median age 3.8 years) with vesicoureteral reflux underwent unilateral or bilateral cross-trigonal ureteral reimplantation (352 ureters). All children received a single dose of gentamicin (2 mg/kg body weight) and a preoperative bladder rinse with 10% polividone-saline solution. A transurethral catheter was also left postoperatively for 2 (unilateral) or 3 (bilateral) days. The ureter was stented with a 8-22 cm multilength catheter. At 3 weeks postoperatively, the ureteral catheters were removed and investigated for bacterial colonization.

Of the 209 children, 10 (4.8%) developed a urinary tract infection within the first 6 weeks after ureteral reimplantation. Of the remaining 199 children without any symptoms, 13 (6.5%) had a positive urine culture at removal of the catheters. Of the 199 children without any symptoms, 90 (45.2%) had a positive culture of one or more segments of the double-J catheter.

Although the colonization rate of ureteral stents in our study was 42.9%, the rate of urinary tract infection during the first 6 weeks after ureteral reimplantation using indwelling ureteral stents was only 4.6%. We have concluded that the clinical significance of bacterial colonization of an indwelling ureteral stent is low, and therefore, ureteral stents can be used safely.
