Summary
Sepsis disrupts kidney microcirculation, causing acute kidney injury even with normal blood flow. Understanding these microvascular changes is key to developing new treatments for sepsis-induced kidney failure.
Area of Science:
- Nephrology
- Critical Care Medicine
- Pathophysiology
Background:
- The renal microcirculation is vital for kidney oxygen and blood supply.
- Sepsis can impair renal microvascular function, leading to acute kidney injury (AKI).
- This dysfunction can occur despite preserved macrovascular perfusion.
Purpose of the Study:
- To review the pathophysiology of renal microcirculation during sepsis.
- To explore the mechanisms contributing to sepsis-induced AKI.
- To highlight emerging technologies for studying renal microcirculation.
Main Methods:
- Review of existing literature on sepsis and renal microcirculation.
- Discussion of pathophysiological mechanisms including endothelial dysfunction, inflammation, oxidative stress, and coagulopathy.
- Overview of new in vivo technologies for renal microcirculation research.
Main Results:
- Sepsis-induced endothelial dysfunction is driven by inflammatory, oxidative, and nitrosative factors.
- Coagulative disorders and glycocalyx disruption contribute to microcirculatory dysfunction.
- Emerging technologies offer new ways to study renal microcirculation in sepsis.
Conclusions:
- Alterations in renal microcirculation are a significant factor in sepsis-induced AKI.
- Understanding these microvascular changes is crucial for therapeutic development.
- Advanced technologies will improve our comprehension and treatment strategies for AKI in sepsis.

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

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 kidneys are vital organs responsible for filtering and cleaning blood, removing waste products, and regulating electrolyte levels. To perform these essential functions, they require a constant and robust blood supply.
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of...

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...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

The kidneys are vital organs responsible for regulating blood filtration, waste excretion, and fluid balance, all of which are crucial for maintaining homeostasis. Renal physiology examines renal blood flow, glomerular filtration, and urine formation, ensuring the body’s internal environment remains stable.Renal Blood FlowThe kidneys receive about 20-25% of the cardiac output, typically around 1200 mL of blood per minute in an average adult. Blood flows into the kidneys through the renal...
