Abstract
Objective: To study the spectrum of different urinary tract abnormalities that could be detected in pediatric patients who underwent VCUG.
Methods: A retrospective study was carried at pediatric radiology unit Ain Shams university hospitals, starting from March 2019 till September 2019. Spectrum of findings were quantified in relation to patients’ symptoms. The number of true acquisitions and fluoroscopic frames, as well as the time of examination, were used as an indicator for radiation dose exposure.
Results: Out of 134 patients who were included in our study and underwent VCUG, the majority was males (n=85, 63.4%) and patients who had more than 24 months and less than 216 months with median (IQR) 72 (48-108)months being (n=82, 61.2%).
We found that half of the cases had abnormal VCUG findings (n=67, 50%). The most common abnormality was vesicoureteric reflux (VUR) (n=38, 28.4%) followed by bladder abnormalities (n=14, 10.5%).The commonest presented complaint was urinary tract infection symptoms (n=58, 43.3%).
Infants below 24 months of age showed more abnormal findings than older children. Males showed more abnormal findings than females.
High-grade VUR (IV-V) was more frequent than low grade. Both recurrent urinary tract infection (UTI) and bladder abnormalities were found to be strong predictors for VUR (p= 0.019 and 0.013, respectively).
The median (IQR) of static films within patients who had abnormal VCUG findings was greater than the median (IQR) of static films within patients who had normal VCUG findings being 7.0 (7.0 – 8.0) versus 6.0 (5.0 – 7.0), respectively with a significant statistically difference (F=6.571, p=0.011).
Conclusion: VCUG can detect different lower urinary abnormalities in children. VUR is the commonest encountered finding during VCUG, especially among patients with recurrent UTI.
