“…Renal length can be measured by several modalities such as renal US, computed tomography (CT) scan, and DMSA scan5,12). CT scan has several disadvantages for children such as radiation exposure and potentially nephrotoxic contrast agent administration, therefore it is recommended as secondary diagnostic tools for further evaluation of renal lesions that are detected with other imaging modalities5,13). Renal US is one of the most common imaging method for assessment of visceral organ without any risk of radiation.…”

PurposeRenal 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.MethodsThis 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).ResultsRenal 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, R2=0.780. In group 1, the formula was renal length (cm)=0.127×age (month)+5.144, R2=0.354, and in group 2, the formula was 0.334×age (year)+6.477, R2=0.829.ConclusionIt is difficult to establish simple formulae in infants (R2=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.

“…These updated algorithms for ultrasound and postnatal hydronephrosis grading highlight the fact that renal parenchymal thickness should be measured and monitored [6,7]. Prassopoulos and Cavouras [8] used CT to measure renal parenchymal thickness in children. They determined that the lower limit of parenchymal thickness in the earlier period of life was 11 mm, whereas that in the current study was 8 mm.…”

“…This necessitates the development of normative standards of parenchymal thickness, as has been done for renal length. Excretory urography and CT have been used for this purpose [8,9]; however, both techniques use ionizing radiation, in contrast to ultrasound. Ultrasound can be performed bedside, is readily available, and can be used repeatedly in children, because no ionizing radiation is used, and is accurate in determining kidney measurements [4].…”

“…The upper urinary tract anatomy is demonstrated by CT slices of total or upper abdomen. On the unenhanced phase, the renal contour and the calyceal system appear well-defined at CT images because of the peri-and pararenal fat and the renal sinuses (5,6) . After intravenous iodinated contrast agent bolus injection, enhancement of the kidneys is observed during the nephrographic phase, and subsequently the renal hila can be bilaterally identified between the anterior and medial regions (7) .…”

OBJETIVO: Obter valores da angulação média dos hilos renais em relação ao plano horizontal, traçado sobre músculos eretores da espinha direito e esquerdo, considerando como parâmetro de referência para as medidas das angulações o centro da coluna vertebral lombar. MATERIAIS E MÉTODOS: Foram analisados 250 exames de tomografia computadorizada de abdomes considerados normais de indivíduos de ambos os sexos, sendo 128 masculinos (idade média de 52,45 ± 17,42 anos) e 122 femininos (idade média de 54,39 ± 18,27 anos), totalizando 500 hilos renais estudados. A angulação média de cada hilo renal em relação ao plano horizontal foi obtida, sendo considerados sempre os ângulos agudos. RESULTADOS: O estudo comparativo entre os sexos mostrou que não houve diferença estatisticamente significante em relação aos ângulos agudos dos hilos renais. A análise estatística mostrou, com intervalo de confiança de 95%, para média do ângulo direito os limites de 40,40° e 44,54° e para o hilo renal esquerdo os limites de 39,91° e 43,23°. CONCLUSÃO: Os hilos renais, independentemente do sexo, apresentam angulações semelhantes. Valores angulares maiores terão anomalia de hiper-rotação ou hiper-rotação exagerada e valores menores terão anomalia de rotação incompleta ou rotação invertida.
