reviewed the outcome of de novo ureteric re-implantation for patient between 1998-2000. All patients
underwent cross-trigonal re-implantation. Post op all children had MCUG and history of further UTI
was recorded. Results were calculated as median, range and percentages. Fisher extract test was
used to calculate P value with a value of <0.05 regarded as significant.
RESULTS
26 patients included, 19 salvage. 14 had bilateral VUR and 5 had unilateral VUR.7 de novo group,
4 had bilateral and 3 had unilateral VUR.In salvage group, 13 were injected once and 6 injected twice.
Median injected amount of in each ureter was 0.5 mls (0.5-2mls). Bilateral ureteric re-implantation
was done in 14 children in salvage group and 4 in de novo group. surgery time in salvage group was
120 minutes (74-360) while in de novo140 (90-180) with a P value of 0.703. Blood loss was minimal
(less than 10 ml) in both groups. No major complications in either group. hospital stay in salvage
group was 5 days (4-7), and in de novo was 6 days (5-10) P value 0.061 follow up was 1 year (1-5)
in both groups. Only one patient in salvage group had persistent unilateral grade 3 VUR on one year
follow up. None of the patients in both groups developed symptomatic UTIs.
CONCLUSIONS
Salvage ureteric re-implantation after failed endoscopic injection has same success rate with no
significant complication rates as compared to denovo ureteric re-implantation for high grade primary
VUR.

PURPOSE
Renal scintigraphy is routinely used to study renal impairment in patients with vesicoureteral reflux
(VUR), but it is invasive and requires radiation exposure. The aim of our study was to analyze if
renal ultrasound (US) is a good predictor of relative renal function (RRF),measured on renal DMSA
scan.
MATERIAL AND METHODS
A retrospective review of all patients with VUR controlled in our division between 2008 and 2016 was
performed. We registered the following variables: sex, reflux grade, laterality, comorbidities, US
renal volume (measured as an ellipsoid volume), US relative renal volume (US-RRV) and DMSA-
RRF. We excluded patients with bilateral or secondary reflux or those with comorbidities.US-RRV
and DMSA-RRF were compared, correlation was studied and the predictability of US to assess
relative renal function was measured.
RESULTS
We reviewed 387 patients, 82 of which had a unilateral primary VUR and no comorbidities. We
registered 41 males and 41 females, with 46 left and 36 right reflux; 39 were low graded (I-III)
and 43 high graded (IV-V).US-RRV strongly correlates with DMSA-RRF (R2=0.849, p<0.001), fol-
lowing the linear function: RRF=0.966*RRV-0.338. US-RRV overestimated DMSA-RRF by 4.4%
(p<0.001).The efficacy of US-RRV in predicting a DMSA-RRF<40% had an 87.5% sensitivity for
RRV<40%, and the area under the ROC curve was 0.82 (0.73-0.91, p<0.001).
