Introduction:

We sought to analyze if there were any factors that would indicate the diagnosis of dilating VUR (≥grade 3) in the second VCUG where the first one was normal. 

Material and methods:

Patients who underwent VCUG between 2012-2017 were retrospectively reviewed. Within the cohort, patients who required more than one VCUG were abstracted and those with an abnormal first VCUG (VUR, posterior urethral valve, etc.) were excluded. Factors such as; age, gender, lower urinary tract dysfunction (LUTD), renal scar, recurrent UTI, abnormal ultrasonography findings (bladder abnormalities/variable degrees of hydronephrosis), and inadequate technique (absence of voiding phase) were noted. 

Results:

Out of 455 patients with a normal first VCUG, a total of 25 patients were found to have undergone more than 1 VCUG (19 girls, 6 boys; mean age 6±3years). Mean time period between the two VCUGs were 19±18months. VUR was detected in 11 patients, while dilating VUR was discovered in 7 patients. Among those, 6 patients were diagnosed with bilateral VUR, 5 of which were ≥grade 3. Recurrent UTI was found to be the only factor that would indicate dilating VUR in the second VCUG (p=0,049). Interestingly, no VUR was detected in cases that were performed after a first VCUG with inadequate technique.  

Conclusions:

In our study, recurrent UTI was shown to be the sole factor that would indicate the diagnosis of dilating VUR in the second VCUG.
