Kidney Structure01:45

Kidney Structure

75.5K
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.

Kidney Transplant I: Introduction

496
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

External Anatomy of the Kidney

3.9K
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...

Internal Anatomy of the Kidney

7.0K
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.

Acute Kidney Injury I: Introduction01:22

Acute Kidney Injury I: Introduction

797
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Area of Science:

  • Urology
  • Robotics
  • Medical Imaging

Background:

  • Ureteroscopy is crucial for diagnosing and treating urinary tract conditions like hematuria, tumors, and calculi.
  • Conventional ureteroscopy faces limitations including ergonomic challenges, visualization difficulties, and significant radiation exposure.
  • Current methods require extensive manipulation under fluoroscopy for comprehensive kidney surveillance.

Purpose of the Study:

  • To develop a robotic system for precise control of a flexible ureteroscope.
  • To reduce radiation exposure for urologists during ureteroscopic procedures.
  • To enhance visualization and maneuverability within the urinary tract.

Main Methods:

  • Development of a robotic system with three degrees of freedom control for a flexible fiber-optic ureteroscope.
  • Integration of a joystick interface, brushless motors, and a quick-mount design.
  • Evaluation using a kidney phantom with MRI-compatible fiducials, image registration via electromagnetic tracking, and paired-point registration.

Main Results:

  • The robotic system successfully controls ureteroscope tip movement with precision.
  • The prototype facilitates a steady platform and quick integration of the ureteroscope.
  • Initial evaluations using a phantom demonstrate the feasibility of image registration and tracking.
