Pak Paed J Jan ;37(4):222-5.

Aim: The aim of this study was to assess renal ultrasound in pediatric patients admitted with uncomplicated urinary tract infection. Patients and methods: This retrospective study was carried out in Abuzar pediatric hospital. Duration of study was 3 year from March 2006. Cases with positive urinary culture were included in this study. Positive urinary culture was defined as 100,000 CFU/ml of midstream sample or urine bag or 10,000 CFU/ml in suprapubic sample. Sex, age, sonographic findings, VCUG, and DMSA scan findings were recorded. T-Test, chi-square, and ANOVA was used for comparison. SPSS ver 13.0 (SPSS Inc, Chicago, Il, USA) used for analysis. Results: In our study 625 cases were included. Hydronephrosis (56,40%); bladder wall thickness 33 (23.57%); hydroureter 13 (9.29%); parenchymal echogenicity 8 (5.71%), and stone 6 (4.29%) were the most common findings. Of 538 renal utrasonogram, 398(73.97%) were normal and 140 were abnormal (26.03%) (P<0.0001). Sensitivity, specificity, positive predictive value and negative predicative value of RUS for VUR were 42.68%, 78.96%, 38.04%, and 81.99% respectively. Conclusion: In cases with UTI, most of the renal ultrasound was normal. Hydronephrosis was the most common identified abnormality among cases with VUR.
