"Kidney measure" children

Bin Xu, Guoping Jiang, Jingjing Ye, Jin He, Wangfang Xie
PURPOSE: To evaluate the renal cortex stiffness in children with glomerular disease by shear wave based elastography point quantification (ElastPQ), and to investigate the association between shear wave velocity (SWV) in the renal cortex and age in normal children, and the inter-gender differences. MATERIALS AND METHODS: One hundred and five children who were pathologically confirmed with glomerular diseases were selected as the disease group. Meanwhile, 120 healthy children were selected as the control group...

BACKGROUND: Kidney measures in early life are associated with kidney disease in later life. We hypothesized that these associations are partly explained by common genetic variants that lead to both smaller kidneys with lower kidney function in early childhood and kidney disease in adulthood. METHODS: We examined in a population-based prospective cohort study among 4,119 children the associations of a weighted genetic risk score combining 20 previously identified common genetic variants related to adult eGFRcreat with kidney outcomes in children aged 6...

BACKGROUND: Genes for tuberous sclerosis complex (TSC) type 2 and autosomal-dominant polycystic kidney disease (ADPKD) type 1 are both encoded over a short segment of chromosome 16. When deletions involve both genes, an entity known as the TSC2/ADPKD1 contiguous gene syndrome, variable phenotypes of TSC and ADPKD are exhibited. This syndrome has not been reviewed in the radiology literature. Unlike renal cysts in TSC, cystic disease in TSC2/ADPKD1 contiguous gene syndrome results in hypertension and renal failure...

OBJECTIVE: To assess the effects of chronic erythrocyte transfusions on prevalence of sonographic incidence of organ damage in children with sickle cell anemia (SCA). STUDY DESIGN: Children (N=148; mean age, 13.0 years) with SCA, receiving chronic transfusions (average, 7 years), underwent abdominal sonography at 25 institutions. After central imaging review, spleen, liver, and kidney measurements were compared with published normal values. Potential relations between ultrasound, clinical, and laboratory data were explored via analysis of variance, Student t test, and Cochran-Mantel-Haenzel tests of non-zero correlation...

BACKGROUND: Xanthogranulomatous pyelonephritis is an uncommon form of chronic pyelonephritis rarely seen in children. Preoperative diagnosis is difficult and management is still obscure. AIM: The authors report on a focal pseudotumoral case and discuss therapeutic modalities. CASE: A 2-year-old boy was admitted for a 2-weeks history of fever and right flank pain. Physical examination revealed a right lumbar mass. White blood cell count was 12...

Information about growth of kidney structures in early life is limited. In a population-based prospective cohort study, from foetal life onwards, we constructed reference curves for kidney growth from the third trimester of pregnancy until early childhood, using data from 1,158 healthy children. Kidney size, defined as length, width, depth and volume, was measured in the third trimester of pregnancy and at the postnatal ages of 6 months and 24 months. Analyses were based on more than 2,500 kidney measurements...

BACKGROUND: An adverse fetal environment may lead to smaller kidneys and subsequently kidney disease and hypertension in adulthood. The aims of this study are to examine whether kidney size tracks from fetal life to childhood and whether maternal and fetal characteristics are associated with kidney size at the age of 2 years. STUDY DESIGN: Prospective cohort study from fetal life onward. SETTING & PARTICIPANTS: The study was conducted in a group of 688 infants in Rotterdam, The Netherlands...

BACKGROUND: The etiology of Balkan Endemic Nephropathy, (BEN), a tubulointerstitial kidney disease, is unknown. Although this disease is endemic in rural areas of Bosnia, Bulgaria, Croatia, Romania, and Serbia, similar manifestations are reported to occur in other regions, for instance Tunisia and Sri Lanka. A number of explanations have been stated including lignites, aristolochic acid, ochratoxin A, metals, and metalloids. Etiologic claims are often based on one or a few studies without sound scientific evidence...

OBJECTIVE: To evaluate the renal growth pattern in patients with primary vesico-ureteric reflux (VUR) using long-term measurements of split renal function with 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy. PATIENTS AND METHODS: In all, 712 children aged < 16 years (466 boys and 246 girls) with primary VUR were referred to our hospital from July 1991 to December 2000. VUR was diagnosed by voiding cysto-urethrography. The patients were treated either surgically (group 1) or conservatively (group 2) and followed with serial 99mTc-DMSA scintigraphy for up to 10 years...

An incidence of hemolytic-uraemic syndrome as a cause of the acute renal failure in childhood, its early survival rate and long-term sequela quences were compared in the 1970s, 1980s, and 1990s in the same geographical area. 196 children with HUS were treated between 1972-1999. 94% had a typical D+ HUS. The majority were of patients severely ill with 87% requiring peritoneal dialysis of an average 14 days duration. The children were grouped into three 9-year periods for comparison (1972-1980, 1981-1989, 1990-1999)...

The measurement of resistive index (RI = [peak systolic velocity--end diastolic velocity]/peak systolic velocity) by Doppler sonography has demonstrated variable reliability as an indicator of pediatric urinary obstruction. By modifying Doppler studies with the addition of furosemide (diuretic Doppler sonography), we previously found significant differences between 10 nonobstructed and 10 obstructed kidneys in children (median age 7 months). The obstructed kidneys have since undergone surgical repair, and postoperative reevaluation has been performed by diuretic Doppler sonography and diuretic renography...

Kidney length and depth were measured by sonography in 46 normal children fro 0 to 16 years of age. Sonography was used to obtain kidney measurements without the known magnification caused by factors of chemical and photographic nature seen by urography. The results of our study were used to control the age-adapted equipment for renography in children. There was a good correlation between kidney length and depth and variables like age, weight, height and body surface area. The best values were found in the correlations to body surface area...

In uremia, poor growth occurs despite normal to increased levels of insulin and GH. Since serum somatomedin levels measured by RIA and radioreceptor assay are normal in patients with renal failure, while serum somatomedin activity measured by bioassay is low but increased by dialysis, we asked if somatomedin activity could be decreased due to the presence of a low mol wt inhibitor(s). Serum was obtained from eight normal adults and eight uremic patients before hemodialysis treatment and was fractionated by gel filtration...

The axes of the kidneys in children with a thoracolumbar gibbus deformity may be distorted to simulate a horseshoe kidney. Measurements of the angle of the gibbus and the angle of intersection of the renal axes were made in 68 children with thoracolumbar meningomyelocele. Thirty-eight children with a gibbus deformity and thoracolumbar meningomyelocele had an abnormality of the renal axis on supine urography, including 19 (28 per cent) in whom a horseshoe kidney was suggested. Three additional children with a gibbus deformity and thoracolumbar meningomyelocele had a normal renal axis...
