BACKGROUND AND PURPOSE: Implanted foreign bodies are associated with a higher risk of infection. Little has been published on infectious complications associated with ureteral double-J stents. The aim of this study was to define risk factors and characterize the febrile complications of the insertion of double-J stents. PATIENTS AND METHODS: One hundred consecutive cases of retrograde stent insertion (55 men and 45 women) were evaluated retrospectively. Eighty-one patients had an obstructing stone, either in the ureter or at the ureteropelvic junction; 10 had an obstructing tumor; and 9 had hydronephrosis and pain without calculi. Risk assessment was calculated for two major categories: urgent (N = 47) and elective (N = 53) insertion. Potentially confounding factors such as age, sex, accompanying medical problems, and types of prophylaxis were assessed. All but six patients received prophylactic antibiotics prior to stent insertion. RESULTS: All thirteen patients who had fever at the initial evaluation underwent urgent stent insertion. Of the 87 afebrile patients (53 elective and 34 urgent insertions), 22 (25%) developed fever (> or = 38 degrees C) after the procedure. Fever developed in 19 (56%) of the 34 urgent-insertion group who were not originally febrile as opposed to 3 (6%) of the elective-insertion group (P < 0.001). Six of these 22 patients (27%) had a positive urine culture after insertion. None had a positive blood culture, including the 13 patients who underwent the procedure while febrile. CONCLUSIONS: Urgent insertion of a double-J stent is associated with a high risk of fever but a favorable outcome.
