WCE 2018: Proposal for a Simple Anatomical Classification of the Pelvicalyceal System for Endoscopic Surgery

Paris, France (UroToday.com) Ureteroscopic and percutaneous stone surgeries are increasing worldwide, but no two patients are alike and some patients’ renal anatomies could differ drastically. Currently, there is no universal nomenclature for the classification of kidney anatomy with regard to the pelvicalyceal system. Due to this, the ability to describe detailed ureteroscopic findings and share common information about the position of a stone or the appropriate puncture site for a percutaneous approach is greatly reduced. Therefore, Dr. Ryoji Takazawa and his team of clinical urologists at the Tokyo Metropolitan Ohtsuka Hospital in Tokyo decided to take matters into their own hands and develop a universal classification system that can be used worldwide. 

WCE 2018: Single-Use Grasper Integrated Flexible Cystoscope for Stent Removal: Micro-Costing Analysis Based Comparison

Paris, France (UroToday.com) For this study Dr. Michael Souriel performed a cost analysis on the use of a recently commercially available single-use flexible cystoscope with integrated grasper (Isiris, Coloplast). He compared the cost of using this device for patient stent removal in an outpatient setting versus using a standard reusable cystoscope and stent grabber. 

WCE 2018: Moses and the Stone: In Vitro Comparison of a Novel Laser Technology to Short and Long Pulse in a Stone Dusting Model

Paris, France (UroToday.com) For this presentation, Dr. Brenton Winshop introduced Moses technology as a novel Holmium: YAG laser pulse system that minimizes stone retropulsion and improves stone fragmentation even when the laser is not in direct contact with the stone. For his study, he aimed to assess the ablation efficiency of Moses technology in laser lithotripsy using an in vitro model.

WCE 2018: Lessons Learned from Open to Laparoscopic to Robotic-Assisted Surgery

Paris, France (UroToday.com) Ali Riza Kural, MD gave a summary regarding the changes in the approach to prostate cancer throughout the years, from diagnosis to treatment. In the past, nearly all patients diagnosed with low risk prostate cancer were offered treatment (radiation or surgery) and were ideal candidates for nerve-sparing radical prostatectomy (RP). Thanks to a series of publications with long-term follow-up evaluating the role of active surveillance, many patients with low risk prostate cancer are now able to avoid radical treatments that are associated with morbidity and a decrease in their quality of life.

WCE 2018: Feasibility of a Non-Opioid Pathway for Postoperative Symptom Control After Ureteroscopy

Paris, France (UroToday.com) The opioid epidemic in recent years has continued to become a growing problem around the world, especially in the United States. The implication and expectation for patients to receive opioids for pain following surgical procedures has caused addiction and health risks that have reached crisis levels. Dr. David Sobel and his team of endourologists at the University of Vermont Medical center have recognized this drastic issue and have begun efforts to implement non-opioid protocols for outpatient urologic surgery.

WCE 2018: Measuring Deployment Forces During Passage of an Ureteral Access Sheath in the Porcine Ureter: “If it don’t go easy, it don’t go at all”

Paris, France (UroToday.com) As an introduction to his talk Dr. Kamaljot Kaler stated that the widespread use of ureteral access sheaths during ureteroscopy has been limited due to concerns regarding ureteral injury. For his study, the team at UC Irvine developed a ureteral access sheath deployment force sensor to determine a measurable amount of force that causes significant ureteral injury within a juvenile porcine model.

WCE 2018: Quantitative Assessment of Effectiveness of Ultrasonic Propulsion of Kidney Stones

Paris, France (UroToday.com) In today’s urologic practice, surgeons are constantly trying to determine new ways of improving patient care for stones, especially with the use of new technology. At the University of Washington School of Medicine, new ultrasonic technology has recently been created which has the ability to reposition stones in the urinary tract. Dr. Patrick Samson is one such physician who helped develop the technology in Seattle and excitedly shared his center’s initial experience with the ultrasound device. The researchers attempted to determine the device’s feasibility in 13 awake and 2 anesthetized subjects. They wished to determine the safety and effectiveness of the new ultrasound transducer design, while also using ureteroscopic observation to quantify the number of kidneys in which stones were repositioned.
