Imaging Studies VII: Vascular Imaging

134
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Hemodialysis I: Introduction

706
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...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Summary

Percutaneous renal biopsies (PRBs) using 16-gauge needles yield optimal samples for both native and transplant kidneys. An 18-gauge needle compromises diagnostic accuracy without improving safety in transplant biopsies.

Area of Science:

  • Nephrology
  • Radiology
  • Urology

Background:

  • Percutaneous renal biopsies (PRBs) are increasingly performed by radiologists.
  • The use of 18-gauge needles may compromise biopsy adequacy.
  • This study compares the adequacy and safety of PRB using 14-, 16-, and 18-gauge needles.

Purpose of the Study:

  • To compare the adequacy and safety of percutaneous renal biopsies (PRBs) using different automated needle sizes.
  • To determine the optimal needle gauge for PRB of native and transplant kidneys.

Main Methods:

  • A retrospective analysis of 1,615 PRBs (592 native, 1,023 transplant) performed between 2002 and 2019.
  • Comparison of biopsy adequacy (glomeruli per core) and safety outcomes (hematoma, complications, transfusion) based on needle size (14g, 16g, 18g).
  • Real-time ultrasound guidance was used for all procedures.

Main Results:

  • 18-gauge needles yielded significantly fewer glomeruli per biopsy and per core compared to 14- and 16-gauge needles.
  • Hematoma, complication, and transfusion rates were similar across all needle sizes for both native and transplant biopsies.
  • 16-gauge needles provided a comparable number of glomeruli to 14-gauge needles in native kidneys.

Conclusions:

  • A 16-gauge needle provides an optimal sample for PRB of both native and transplant kidneys.
  • The use of an 18-gauge needle compromises diagnostic accuracy in transplant biopsies without enhancing safety.
  • Radiologists should consider using 16-gauge needles for PRB to ensure adequate sample size and diagnostic yield.
