The Impact of Irrigation Fluid Temperature on Thulium Fiber Laser Stone Ablation: An In-Vitro Study "Presentation"

Details
Andrei Cumpanas presented a study on the impact of irrigation fluid temperature on thulium fiber laser stone ablation, finding that while higher fluid temperatures were associated with increased ablation cone volume, the clinical significance was minimal compared to an increase in laser energy. Biography: Andrei D. Cumpanas, MD, Researcher, Department of Urology, The University of California, Irvi...

In-vivo Acute Ureteral Dilation using Electromotive Drug Administration (EMDA) in the Porcine Ureter "Presentation"

Details
Bruce Gao presented research on Electromotive Drug Administration in the Porcine Ureter, demonstrating its potential to enhance drug delivery and ureteral distensibility, offering new insights into acute ureteral dilation. Biographies: Bruce M. Gao, MD, Urologist, University of California Irvine, Irvine, CA Read the Full Video Transcript {article title="4003-i-aua-pd10-02-in-vivo-acute-ureteral-di...

Ureteral Strictures Following Ureteroscopic Ureteral Wall Injury: A Previously Unidentified Concern “Presentation”

Details
Andrei Cumpanas presented a study on ureteral strictures following ureteroscopic ureteral wall injury, highlighting a previously unidentified concern. The study aimed to determine the risk of post-ureteroscopic ureteral stricture formation based on the depth of injury into the ureteral wall, revealing that stricture rates increase significantly when the ureteral wall is partially or fully transgre...

Immersive Virtual Reality for Percutaneous Nephrolithotomy (PCNL): “The More you Know, the Safer and More Effective the Outcome” “Presentation”

Details
Andrei Cumpanas from UC Irvine presented a study on using immersive virtual reality (IVR) models prior to percutaneous stone removal, showing that IVR improved surgeon understanding of case anatomy, altered calyx choice in 30% of cases, and led to better surgical outcomes with reduced complications. Biography: Andrei D. Cumpanas, MD, Researcher, Department of Urology, The University of California,...

Artificial Intelligence Convolutional Neural Network for Efficient and Accurate CT-based Stone Volume Determination “Presentation”

Details
Andrei Cumpanas presented a study on using an AI convolutional neural network to accurately determine CT-based stone volume, showing that the AI algorithm outperformed traditional ellipsoid formulas in accuracy and precision, especially for larger stones with irregular shapes. Biographies: Andrei D. Cumpanas, MD, Researcher, Department of Urology, The University of California, Irvine, CA Read the...

Assessing Alterations in Stone Burden Among Patients with Medullary Sponge Kidney: A Volumetric Approach “Presentation”

Details
Andrei Cumpanas presented a study on assessing alterations in stone burden among patients with Medullary Sponge Kidney (MSK), showing that CT reports often miss increases in stone volume in MSK patients, leading to a false sense of stable disease.

Surgical Force-Correlating Science with Practice: A Study of the Fore Exerted by Urologists During Ureteral Access Sheath Placement “Presentation”

Details
Amir Lavasani from UC Irvine presented a study on the force exerted by urologists during ureteral access sheath placement, revealing that a significant percentage apply forces above recommended limits, risking high-grade ureteral injury. Biography: Seyed Amiryaghoub M. Lavasani, Clinical Researcher, Department of Urology, University of California, Irvine, CA Read the Full Video Transcript {article...

Immersive Virtual Reality (iVR) for Percutaneous Nephrolithotomy: The More You Know, the Better the Outcome Presentation - Andrei D. Cumpanas

Details
The study presented by Andrei Cumpanas examined the benefits of using an immersive virtual reality model before percutaneous stone removal in 125 patients. The study found that the use of immersive virtual reality resulted in an improved understanding of intra-renal anatomy, better surgical outcomes, and a reduced rate of complications. The group that viewed the virtual reality model had higher ra...

Head-To-Head Energy Transmission of the Super-Pulse Thulium Fiber Laser Versus Holmium Laser in Multiple Fiber Sizes and Settings Presentation - Allen Rojhani

Details
Allen Rojhani presents a study comparing the energy transmission and pressure generated by a super-pulse thulium fiber laser and a holmium laser during lithotripsy. The study used different fiber sizes and settings and recorded the parameters using an energy meter and pressure sensor. The results showed that the thulium outperformed the holmium in most settings, transmitting more energy and genera...

Clinical Measurement of Maximum Safe Ureteral Distensibility Using a Novel Force Sensor Presentation - Amanda McCormac

Details
Amanda McCormac presented on Clinical Measurement of Maximum Safe Ureteral Distensibility Using a Novel Force Sensor, which aimed to determine the natural distensibility of the human ureter using the UCI force sensor. The study involved 75 patients undergoing uteroscopy, and the results showed that the unstented human ureter can safely size to an average circumference of 14 French and 16 French if...
