Kidney dimensions in ultrasound compared to somatometric parameters in normal children
Insights
This study established regression equations for kidney size and parenchymal mass in children aged 4 weeks to 16 years. These equations enable precise individual determination of renal morphometrics using sonography.
Area of Science:
- Pediatric Nephrology
- Medical Imaging
- Human Morphology
Background:
- Accurate assessment of renal morphometrics is crucial for pediatric health monitoring.
- Standardized sonographic measurements provide valuable data for evaluating kidney development and function.
- Existing methods may lack precision for individual pediatric renal assessment.
Purpose of the Study:
- To establish sonographic reference standards for kidney dimensions and volume in children.
- To correlate renal morphometric data with somatometric parameters in a pediatric cohort.
- To develop regression equations for individual determination of renal size and parenchymal mass.
Main Methods:
- Sonographic investigation of kidneys in 196 healthy children aged 4 weeks to 16 years.
- Collection of somatometric data including bodyweight, body length, and various body measurements.
- Calculation of mean values and multiple regression analysis for kidney length, parenchymal areas, and volume (PEV) across five age groups.
Main Results:
- Detailed morphometric data (length, width, depth, parenchymal areas, PEV) were documented for all children.
- Multiple regression analysis yielded specific equations for kidney length, parenchymal areas, and volume.
- Established age-specific reference ranges for renal parameters in the pediatric population.
Conclusions:
- Sonographic morphometric analysis provides a reliable method for assessing pediatric kidney size and parenchymal mass.
- The developed regression equations allow for accurate, individualized renal assessment in children.
- This study offers valuable tools for pediatric nephrology and clinical practice.
Abstract:
In 196 children aged between 4 weeks and 16 2/12 years a sonographic investigation of kidneys was performed and put into relation to somatometric data including bodyweight (BW) bodylength (BL), length of the trunk and the upper and the lower limb, breadth of thorax and pelvic, head circumference, maximum cranial length and maximum cranial breadth. None of the children had signs of renal disorder. Morphometric data, as kidney length, width, depth, parenchymal areas in longitudinal and transverse sections and the prolate ellipsoid volume (PEV) were documented. The children were divided into five groups (group 1: 2-6 months, group 2: 6-31 months, group 3: 31-99 months, group 4: 99-131 months, group 5: 131-194 months). Mean values of all parameters were calculated. For each group a multiple regression analysis was performed and a regression equation of kidney length, parenchymal areas and volume was established. This method allows an individual determination of renal size and parenchymal mass.
