Summary
This study found that body mass index (BMI), male gender, and height are key factors influencing kidney size (craniocaudal diameter, cortical width, and parenchymal width). Kidney position also affects renal size, while contralateral kidney absence impacts renal cortex size.
Area of Science:
- Radiology
- Urology
- Medical Imaging
Background:
- Normal renal parenchyma and upper urinary tract parameters are crucial for accurate diagnosis.
- Establishing normative data aids in identifying renal abnormalities.
- Contrast-enhanced computed tomography (CECT) is a standard imaging modality for renal assessment.
Purpose of the Study:
- To assess normal renal parenchyma and upper urinary tract parameters using contrast-enhanced computed tomography (CECT).
- To develop a mathematical model for normal kidney dimensions.
- To identify factors influencing renal size and morphology.
Main Methods:
- Retrospective observational study of 520 patients with normal CECT scans.
- Detailed measurements of renal dimensions (craniocaudal diameter, transverse diameter, anteroposterior diameter), parenchymal width, cortical width, and kidney rotation were performed.
- Multivariate regression analysis was used to identify influencing factors such as BMI, gender, and height.
Main Results:
- Craniocaudal diameter (CCD) remained elevated until the fifth decade.
- Linear correlations were observed between height and renal dimensions (CCD, cortical width, parenchymal width).
- Body Mass Index (BMI), male gender, and height were statistically significant factors influencing renal size (CCD, cortical width, parenchymal width).
Conclusions:
- Kidney size exhibits a wide range among individuals.
- BMI, male gender, and height are the most significant factors influencing renal dimensions in adults.
- Kidney position and the absence of a contralateral kidney also impact renal size and cortical dimensions.

01:12Internal Anatomy of the Kidney
The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.

01:21External Anatomy of the Kidney
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

01:10Nephrons
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma happens...
01:45Kidney Structure
The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease.

01:25Chronic Kidney Disease I: Introduction
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...
