PURPOSE

Since 2011, AUA pediatric urology guidelines recommends risk based approach for the manage-

ment of pediatric patients with vesicoureteral reflux. For this approach kidney condition must be

known. Detecting renal scar on DMSA scan is important in risk classification . In this study our aim

is to detect if renal parenchymal elasticity measurement by elastosonograpy tecnique could be an

alternative to DMSA scan in determining renal function and scar formation.

MATERIAL AND METHODS

Between November 2015 to April 2016, 25 vesicouretheral reflux patient, age ranging from 3 to

17 years admitted to our pediatric urology clinic, had urinary ultrasound and elastosonography

and datas about 140 renal region were recorded. Datas were upper, middle, lower pole renal

paranchymal thickness and echogenicity obtained by ultrasound and renal upper, middle and lower

pole tissue tension values (ST, SR, R) obtained by static elastosonography. DMSA scan datas

(differentiated function, upper, middle and lower pole parenchymal scar formation) were recorded.

RESULTS

Scar formation and more than 10% reduction in differentiated function in renal scan was statistically

higher in renal units in which parenchymal thinning and echogenicity increase was detected by

ultrasound.

There was no sonoelastografic data difference between renal units with and without differentiated

function decrease. Also there was no sonoelastographic data difference between renal units with

and without scar formation.

CONCLUSIONS

In this study we couldn’t find any statistical significant difference in term of tissue tension values (ST,

SR, R) measured by static elastosonography between renal units with and witout scar formation in

renal scan.
