Abstract |
Purpose: As vesicoureteral reflux (VUR) could lead to
renal functional deterioration when combined with
urinary tract infection, we need to decide whether
operative anti-reflux treatment should be performed at
the time of diagnosis of VUR. Predictive value of
radioisotope voiding cystography (RIVCG) for renal
outcome was tested. Materials and Methods: In 35
children (18 males, 17 females), radiologic voiding
cystourethrography (VCU), RIVCG and DMSA scan were
performed. Change in renal function was evaluated using
the follow-up DMSA scan, ultrasonography, and clinical
information. Discriminant analysis was performed using
individual or integrated variables such as reflux
amount and extent at each phase of voiding on RIVCG, in
addition to age, gender and cortical defect on DMSA
scan at the time of diagnosis. Discriminant function
was composed and its performance was examined. Results:
Reflux extent at the filling phase and reflux amount
and extent at postvoiding phase had a significant
prognostic value. Total reflux amount was a composite
variable to predict prognosis. Discriminant function
composed of reflux extent at the filling phase and
reflux amount and extent at postvoiding phase showed
better positive predictive value and specificity than
conventional reflux grading. Conclusion: RIVCG could
predict renal outcome by disclosing characteristic
reflux pattern during various voiding phases. (Korean J
