Insights
Post-cystography urinary infection (UI) incidence was low at 4.3% in children. Vesicoureteral reflux (VUR) was a significant risk factor for UI after this common diagnostic procedure.
Area of Science:
- Pediatric Radiology
- Infectious Disease Epidemiology
Background:
- Cystography is an invasive diagnostic procedure with potential complications, including urinary infection (UI).
- Limited studies exist on the incidence and risk factors of post-cystography UI, particularly in pediatric populations.
Purpose of the Study:
- To evaluate the incidence of post-cystography urinary infection (UI) in pediatric patients.
- To identify potential predictive factors associated with post-cystography UI.
Main Methods:
- Retrospective review of clinical records for pediatric patients (<15 years) who underwent cystography (radiologic or indirect radionuclide) between 2009-2018.
- UI was defined as occurring within seven days post-procedure. Descriptive and nonparametric statistics were used to analyze data.
Main Results:
- 531 cystograms were performed; 4.3% resulted in post-cystography UI.
- Vesicoureteral reflux (VUR) was diagnosed in 40% of cases and was significantly associated with UI.
- E. coli was the most frequent causative microorganism (52%).
Conclusions:
- The incidence of post-cystography UI in this pediatric cohort was low.
- Vesicoureteral reflux (VUR) is a significant risk factor for post-cystography UI.
- Emphasizes the importance of proper catheterization technique and post-procedure clinical surveillance.
Objective:
Cystography an invasive procedure with potential complications such as urinary infection (UI). There are few studies about the incidence of complications associated with this procedure. The purpose of this study is to evaluate the incidence of post-cystography urinary infection (UI.).
Methods:
Retrospective study with a review of clinical records of patients under 15 years of age, followed in this hospital, who underwent cystography (radiologic or indirect radionuclide) between 2009 and 2018. Post-cystography UI was defined when it occurred until seven days after the procedure. Descriptive and nonparametric statistics were applied to assess possible predictive factors related with post-cystography UI.
Results:
In the study period, 531 cystograms were undertaken (55% indirect radionuclide and 45% radiologic). The mean age at the procedure was 11.5 months; 62% were boys. Every patient had a previous negative urine culture; 50% were under antibiotic prophylaxis at the time of the procedure. The most common indication for the procedure was the post-natal study of congenital hydronephrosis/other nephrological malformation (53%), followed by the study of febrile UI (31%). Vesicoureteral reflux (VUR) was diagnosed in 40% of procedures. Post-cystography UI occurred in 23 cases (incidence of 4.3%). The most frequent microorganism was E. coli (52%). The presence of VUR was significantly associated with the occurrence of post-cystography IU.
Conclusions:
The incidence of post-cystography UI was low in our sample. The presence of VUR was significantly associated with the occurrence of post-cystography UI. The authors highlight the importance of an adequate catheterization technique and the need for clinical surveillance after the procedure.
