Imaging Studies VII: Vascular Imaging

Imaging Studies VII: Vascular Imaging

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...

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

Area of Science:

Urology
Medical Simulation
Surgical Training

Background:

Advances in computing have spurred the development of virtual reality (VR) surgical simulators.
The PERC Mentor™ simulator is specifically designed for training percutaneous renal collecting system access puncture.
This study aimed to validate the efficacy of VR simulation for percutaneous renal access training.

Purpose of the Study:

To validate the use of the PERC Mentor™ virtual reality simulator for training percutaneous renal access.
To assess the impact of simulation-based training on trainees' ability to perform the procedure independently.

Main Methods:

Twenty-one urologists underwent training using the PERC Mentor™ simulator after an instructional video and analog operation.
Training involved 2 hours daily for 2 consecutive days, with objective simulator parameters and subjective Global Rating Scale (GRS) scores recorded.
Trainees were evaluated 24 hours post-training, comparing their performance to an initial attempt.

Main Results:

Initially, no trainees could complete the procedure independently due to lack of experience.
Following VR simulation training, all trainees successfully completed the percutaneous renal access procedure.
Trainees with prior ultrasound-guided percutaneous nephrolithotomy experience demonstrated significantly lower operating times and contrast material usage compared to inexperienced trainees.

Conclusions:

The PERC Mentor™ VR simulator effectively trains individuals with no prior experience in fluoroscopy-guided percutaneous renal access.
The simulator facilitates independent completion of the virtual procedure.
This VR simulator shows potential as a valuable tool for both training and evaluating fluoroscopy-guided percutaneous renal access skills.
