AUA 2018 Stone Disease

AUA 2018: Comparison of Two Digital, Single Use Flexible Ureterorenoscopes (Boston Scientific Lithovue And Pusen Pu3022) - A Prospective Study

San Francisco, CA USA (UroToday.com) The number and availability of single-use flexible ureteroscopes has currently been on the rise as more companies begin to develop scopes in this novel area. There have currently been no in vivo studies to compare the performance of different single use scopes. In lieu of this, Dr. Kam and colleagues sought to compare the Pusen single-use scope vs the LithoVue (Boston Scientific) single-use scope. The reusable Olympus URF-V2 was used as a standard for this comparison.

AUA 2018: Portable Digital Endoscopy Using Laptop Adaptor Device

San Francisco, CA USA (UroToday.com)  Brian Calio, MD presented his institution’s experience using a portable, digital ureteroscope that uses a laptop as its video monitoring system. As an introduction to his talk, Dr. Calio explained the importance of ureteroscopy in urology today. However, he also explained that ureteroscopy presents a financial obstacle to many countries. These high costs can exceed $30,000 and includes the cost of a reusable rigid and/or flexible scope. CCD/CMOS video camera with coupler, halogen light source, video recorder.

AUA 2018: The Utility of Emergently Placed Interventional Radiology Nephrostomy Tube Tracts for Subsequent Percutaneous Nephrolithotomy

San Francisco, CA USA (UroToday.com) Patients undergoing percutaneous nephrolithotomies require optimal percutaneous access to remove kidney stones larger than 2 cm. The primary goal for this access is to safely drain urine, usually completed by interventional radiology. Dr. Kaitlan Cobb of George Washington University and her research team observed the efficiency of nephrostomy tubes placed by IR to obtain percutaneous access in acute settings.

AUA 2018: Holmium Laser Lithotripsy for Ureteral and Renal Stones: Is Dusting Equivalent to Fragmenting?

San Francisco, CA USA (UroToday.com) Dr. Thomas Knoll, from University of Tuebingen, presented research comparing two commonly used holmium laser lithotripsy settings for ureteroscopic stone treatment. The variables of frequency, energy, pulse length and shape impact the laser’s effect on the stone and therefore the outcomes of dusting and fragmentation. As ureteroscopy has become the primary treatment of choice for upper tract stones, this prospective study of 177 patients aimed to determine the optimum laser settings to improve stone management.

AUA 2018: Perioperative Outcomes of Flexible Ureteroscopy for Urolithiasis using the Sheathless Technique: A Comparative Study

Dr. Benjamin Pradere, the Chief of Clinic at Chru Hôpitaux De Tours, presented on the perioperative outcomes using a sheathless method for flexible ureteroscopy (fURS). As a result of advancing capabilities of flexible ureteroscopes, the interest in sheathless and wireless approaches to fURS has increased. The author opened by explaining current literature that correlates ureteral access sheaths (UAS) deployment to a possible increase ureteral damage and ureteral lesions formation during standard fURS.

AUA 2018: A Novel Concept for Reporting Outcomes of a Successful Treatment in Endourology for Stones: The Stone-Fecta

San Francisco, CA USA (UroToday.com) Dr. Giovanni Cacciamani, a fellow from the University of Southern California, presented his data on a novel concept for a system for reporting outcomes during URS/RIRS for stones, titled the STONEfecta (Successful Treatment Outcomes in Endourology). Dr. Cacciamani and his team wanted to develop a system to track and influence management decisions of URS and RIRS procedures, as the number of treatments needed to reach stone free rates in the safest way possible in terms of infections and intraoperative complications represents a concern for both patients and surgeons.

AUA 2018: Emergency Room Utilization and Associated Costs for Pediatric vs. Adult Nephrolithiasis

San Francisco, CA USA (UroToday.com) Diana K. Bowen, MD, a Pediatric Urology Fellow from the Children’s Hospital of Philadelphia, Perelman School of Medicine at the University of Pennsylvania, presented data that compared the frequency of visits and associated charges for emergency room encounters during a single stones episode between pediatric and adult patients.
