چکیده
PURPOSE Renal size is an important indicator to determine adequate organ growth in children. The aim of this study was to estimate renal size with Technesium-99m dimercaptosuccinic acid (DMSA) scan and propose a simple formula for predicting renal length in normal Korean children. METHODS This study included 346 children (148 boys and 198 girls; age range, 1 month to 17 years) in whom renal length was measured using the DMSA scan. Patients with anatomical renal abnormalities or acute pyelonephritis were excluded. Children were divided into two groups: 214 children (61.8%) were less than a year old (group 1) and 132 (38.2%) were ≥1 year (group 2). RESULTS Renal length was larger on the left side than the right side, and there was no significant gender-related difference in renal length. We propose the following formula for renal length based on the analysis of the 346 children in our study: the formula was as follows: 4.682×age (month)(0.137), R(2) =0.780. In group 1, the formula was renal length (cm)=0.127×age (month)+5.144, R(2) =0.354, and in group 2, the formula was 0.334×age (year)+6.477, R(2) =0.829. CONCLUSION It is difficult to establish simple formulae in infants (R(2) =0.354). Therefore, further studies including relevant variables are needed for this age group. We proposed formulae to estimate renal length in Korean children over 1 year of age by using the DMSA scan.

Background: Imaging modalities such as voiding cystourethrography (VCUG), direct radionuclide cystography (DRNC), and renal cortical scintigraphy (RCS) with technetium-99m dimercaptosuccinic acid (Tc-99mDMSA), are helpful in detecting possible abnormalities of urinary tract such as vesicoureteral reflux (VUR). However, there are confounding data regarding the preference of these modalities. In ...

UNLABELLED Technetium-99m dimercaptosuccinic acid (Tc-99m DMSA) as a static renal agent is currently the most frequently used agent in the detection of renal scarring, and allows accurate calculation of differential renal function (DRF). But this agent has some disadvantages such as relatively higher radiation dose and time consumption. METHODS The purpose of this study was to evaluate the po...

Introduction. Fibroblast growth factor 2 (FGF2) is a potent mitogenic factor of cortical fibroblasts and induces kidney fibrosis. We hypothesized that serum levels of FGF2 has an association with the severity of vesicoureteral reflux (VUR) and renal parenchymal scar. Materials and Methods. Between 2007 and 2009, a total of 28 children with VUR were enrolled in this study and were compared with ...
