Renal Corpuscle

Renal Corpuscle

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...

Hemodialysis I: Introduction

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Compact Bone

Compact Bone

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Dialysis

Dialysis

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Dialysis

Dialysis

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Spongy Bone

Spongy Bone

All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Background:

Dialysis patients experience a high incidence of skeletal fractures.
Existing tools are inadequate for predicting bone fragility in this population.
Bone microarchitecture analysis offers a potential avenue for improved risk assessment.

Purpose of the Study:

To evaluate the utility of microcomputed tomography (µCT) for assessing bone microarchitecture in dialysis patients.
To compare different imaging modalities for bone analysis in patients with fractures.

Main Methods:

Analysis of 12 trans-iliac bone biopsies from patients with recent fractures.
Bone microarchitecture assessment using 2D histology, 3D-µCT, and high-resolution peripheral quantitative computed tomography (HR-pQCT).

Main Results:

Trabecular bone volume measurements varied between 2D histology, 3D-µCT, and HR-pQCT.
No significant correlation was found for trabecular microarchitectural indices across the different methods.
3D-µCT demonstrated reliable measurement of cortical thickness (Ct.Th), which was lower in patients with multiple vertebral fractures.

Conclusions:

3D-µCT is a dependable technique for quantifying cortical bone in bone biopsies.
Further prospective research is needed to establish the role of 3D-µCT in predicting fracture risk in dialysis patients.
