Urinary tract infection in children undergoing diagnostic voiding cystourethrography.
J Surg Pak Jan ;15(2):68-72.

Objective To determine the frequency of urinary tract infection (UTI) in children undergoing voiding cystourethrogram (VCUG) and to find out congenital urinary tract anomalies (CUTA) that may predispose to such an outcome. Study design Descriptive case series. Place & Duration of study The Department of Pediatric Nephrology, National Institute of Child Health (NICH) Karachi, from September 2007 to March 2008. Methodology A total of 100 children of one month to 12 years underwent voiding cystourethrogram following standard technique. For post-VCUG-UTI, urinalysis and culture and sensitivity (CS) were done in all cases. The demographic data, indications, post-VCUG- UTI, type of pathogens and radiological diagnosis were recorded. Descriptive statistics were used for analysis. Results Out of 100 patients there were 70 males and 30 females. Mean age was 3.05 ± 2.9 years (range one month - 12 years). Post- VCUG-UTI was found in 12 patients. Most common pathogen was E. coli (n= 5/12, 42%) followed by Pseudomonas aeruginosa (n= 4/12, 33%) and Klebsiella (n=3/12, 25%). CUTAs diagnosed on VCUG were found in 59 cases. Posterior urethral valves (PUV n-26) and primary vesicoureteral reflux (VUR n-22) were the two most common CUTAs and probably the risk factors for UTI in addition to catheterization. Conclusions This study showed a high frequency of post-VCUG-UTI in children. Both VCUG and CUTAs may be considered as risk factors for UTI..
