Background and Objective: Definitive diagnosis of vesicoureteral reflux (VUR) is by voiding cystourethrogram (VUCG), yet this is an

uncomfortable procedure and does not detect renal scars. Technetium 99m Tc dimercaptosuccinic acid (DMSA) scintigraphy is currently the

standard test for detecting renal scars. The aim of the current study was to examine the capability of urinary system ultrasonography (USG) and

DSMA to distinguish VUR, and thus to replace VUCG .

Methods: Analysis of medical records of children, from birth to age 9 years, with symptoms of urinary tract infection who underwent VUCG for

detection of VUR at one medical center .

Results: Of 88 children, 73 (83%) were girls, 72 (97%) had fever. VCUG detected VUR in 33 (38%). USG revealed abnormal findings in 44%

(14/32) of the children with VUR and 41% (22/54) of those without VUR. Of the 36 children with abnormal findings on DSMA, 33% were without

VUR and 24 (67%) with VUR: 8/24 (33%) had VUR grade 1–2 and 16/24 (67%) VUR grade 3–5. Of the 33 with normal DSMA findings 27 (82%)

were without VUR and 6 (18%) with VUR: 4/6 (67%) had VUR grade 1–2 and 2 (33%) VUR grade 3–5 .

Conclusions: USG findings were not shown to distinguish VUR or to be associated with DMSA findings. DMSA does not appear as a means of

replacing VCUG for the detection of VUR, since an abnormal DMSA occurred in almost one–third of children with UTI and without VUR

Abeviations: UTI: urinary tract infection; VUR: vesicoureteral reflux; VCUG: voiding cystourethrogram; DMSA: dimercaptosuccinic acid;

USG: ultrasonography .
