INTRODUCTION: Postnatal evaluation of prenatal hydronephrosis (PNH) often
includes a voiding cystourethrogram (VCUG) for VUR assessment. Despite limited
supporting data, VCUG is currently recommended if postnatal renal and bladder
ultrasound (RBUS) reveals moderate/severe hydronephrosis (HN) or hydroureter
(HU). Recent studies have shown VUR is more accurately diagnosed by using certain
sonographic findings as criteria for obtaining VCUG. Uroepithelial thickening
(UET) of the renal pelvis is a finding associated with high-grade vesicoureteral
reflux (HGVUR); however, the clinical significance of UET with PNH has not been
studied. OBJECTIVE: We sought to determine if the presence of UET implies
increased risk for VUR, and to investigate whether UET can improve the test
characteristics of RBUS for VUR. STUDY DESIGN: We retrospectively analyzed
postnatal RBUS and VCUG findings in infants ?30 days undergoing evaluation for
"prenatal hydronephrosis" over an 11-year period. We used logistic regression to
identify factors associated with VUR. Test characteristics of RBUS for HGVUR were
compared based on the presence of UET and two criteria sets to define abnormal
RBUS. Criteria set 1 consisted of HN SFU grade 3-4 and/or HU; criteria set 2 was
defined by the presence of two of following: UET, HU, duplication, and/or renal
dysmorphia. RESULTS: Of 135 patients, 39 (29%) had VUR, of whom 16 (41%) had
HGVUR. UET was significantly associated with VUR (p < 0.001), and the sensitivity
for HGVUR based on UET alone was 94%. On multivariable analysis, UET, HU,
duplication, and renal dysmorphia remained significant independent predictors of
HGVUR. Compared to criteria 1, using criteria 2 resulted in 43 fewer VCUGs, and
significant improvement in sensitivity and specificity for HGVUR (Table).
DISCUSSION: Consistent with previous studies, HN alone on postnatal RBUS has
little value in predicting the presence or severity of VUR. This study is the
largest known series to evaluate UET in the setting of PNH, and our results
demonstrate that UET, as well as HU, duplication and renal dysmorphia, are
independent sonographic findings predicting HGVUR. Using our proposed criteria,
the probability of HGVUR is fourfold more than the prevalence described in the
literature, and importantly, when compared to the criteria recommended by the SFU
and AUA, would have resulted in 53% fewer VCUGs while missing zero cases of
HGVUR. CONCLUSION: In infants with PNH, the sonographic findings of UET, HU,
duplication and renal dysmorphia independently indicate greater risk of HGVUR,
and the sensitivity and specificity of RBUS for HGVUR is markedly improved when
at least two of the four are present.
