Installation or exchange of double-J ureteral stent is a risk factor of febrile urinary tract infection in a compromised host
Abstract Background : To study the predictors of febrile urinary tract infections (febrile UTI) after the placement of Indwelling double-J ureteral stent (DJS), and effective prophylactic antimicrobial agent. Methods : Installation or exchange of 298 double-J stents (DJS) ( 66 men and 232 women, median age 67 years, range 42~86) were examined. 258 patients had been given prophylactic antibiotic therapy after the placement of stents, 40 patients with no prophylactic antibiotic therapy. Results : 14 patients (4.2%) had febrile UTI after the placement of the stent. The pathogens was identified from the pelvic urine culture of 9 patients with febrile UTI. Enterococcus faecalis was the most common pathogen, it accounted for 25.0% of all pathogens. Compromised host was potential risk factors for the febrile UTI in patients with DJS. 1.1% of patients who received with fluoroquinolones or 4.7% of patients with cephalosporin developed a febrile UTI. Conclusions : Indwelling DJS is a risk factor of febrile UTI in a compromised host, fluoroquinolones may be effective for preventing febrile UTI after placement of DJS.
