#WCE2014 - Determinants of fluoroscopy time during percutaneous nephrolithotomy (PCNL) - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: To assess factors affecting Fluoroscopy Time (FT) during PCNL.

#WCE2014 - Does time interval from stone diagnosis to treatment affect outcomes? - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Limited resources at publically funded hospitals may demand that definitive surgical intervention for stones be delayed weeks or months, necessitating drainage to stabilize the patient and protect renal function. We sought to analyze the impact of time to treatment on patient morbidity and healthcare resource utilization.

#WCE2014 - Brian R. Matlaga, MD is the recipient of the 2014 Arthur D. Smith Endourology Lectureship - Interview

TAIPEI, TAIWAN (UroToday.com) - The recipient of this year’s Arthur D. Smith Endourology Lectureship is Brian R. Matlaga, MD, associate professor of urology at the Johns Hopkins University School of Medicine and director of ambulatory urologic care
 at the James Buchanan Brady Urological Institute in Baltimore, MD.

#WCE2014 - Single versus dual-console robot-assisted radical prostatectomy: 
Impact on intraoperative and postoperative outcomes in a teaching institution - Session Highlights

TAIPEI, TAIWAN (UroToday.com) - Many resident training programs have adopted a dual console Intuitive Da Vinci Robotic Surgical system in hopes of aiding robotic surgical training. This allows two surgeons to control the robotic arms at the same time, in parallel, or quickly alternating between the surgeons.

#WCE2014 - A comparison of patient comfort and satisfaction after robotic 
prostatectomy with suprapubic tube versus urethral catheter drainage - Session Highlights

TAIPEI, TAIWAN (UroToday.com) - Researchers from UT Southwestern sought to answer a simple question in robotic prostatectomy (RALP): Is a post-operative suprapubic tube superior to a urethral catheter with regards to pain and satisfaction?

#WCE2014 - Complete resolution of huge anterior calyceal diverticulum case report - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Calyceal diverticulum is rare (incidence rate 0.2%-0.6%) and usually related with stone formation, gross hematuria, and infection. Calyceal diverticulum is usually treated by laparoscopic or percutaneous renal access approach. Percutaneous renal access approach is traditionally applied for small calyceal diverticulum (< 2 cm). Laparoscopic approach is usually introduced for larger or anterior calyceal diverticulum, but its postoperative morbidity is not as good as percutaneous method.

#WCE2014 - Crowd-sourced assessment of technical skills (C-SATS): Validation through the basic laparoscopic urologic surgery (BLUS) curriculum - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Crowdsourcing is the practice of obtaining services from a large group of people; typically from an online community such as the Amazon.com Mechanical Turk Project. We hypothesized that the ‘crowd’ could score performances comparably to scores derived from expert surgeons of dry lab laparoscopic skill tasks videotaped during the AUA BLUS curriculum validation project.

#WCE2014 - Single port laparoscopic hernioplasty—cost effect debate - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Inguinal hernia is a common disease and the operation today has been established to progress to the single port surgery. The new procedure is feasible and the cost effect is still debated.

#WCE2014 - The acoustic shadow width is a more accurate predictor of true stone size during ultrasound - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Ultrasound images of kidney stones display a bright stone with a distal shadow. We hypothesize the width of the shadow is a more accurate predictor of true stone size than width of the stone image.

#WCE2014 - Can we further improve lower pole stone clearance rates? A randomised controlled study - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Various adjunctive measures have been tested to improve the stone free rates (SFR) for lower pole stones (LPS), but few are randomised or controlled. We report the results of addition of an adjunctive measure (inversion 30 degree head down Trendelenbugh position) to improve the SFR of LCS.

#WCE2014 - Using intraureteral indocyanine green to facilitate robot-assisted ureteral reconstructions - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Enhancing the ability to visually identify the ureter, and distinguish healthy versus nonviable ureter may facilitate robot- assisted ureteral reconstructions (RUR). Indocyanine green (ICG), a fluorescent dye that can be visualized under near- infrared light (NIRF), penetrates tissue and has a high signal-to-noise ratio. We describe our novel technique that utilizes intraureteral injection of ICG and subsequent visualization under NIRF to facilitate RUR and report our outcomes.

#WCE2014 - Robotic kidney transplantation with regional hypothermia: Results from a prospective two-arm non-randomized controlled trial (IDEAL phase 2b) - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Minimally invasive approaches to kidney transplantation (KT) have recently been described. We recently developed and described a novel technique of robotic KT (RKT) using intra corporeal graft cooling. We assessed the comparative effectiveness of RKT and open KT (OKT) by evaluating peri and post-operative outcomes.

#WCE2014 - Stone burden measurement by 3D reconstruction on NCCT is not a more accurate predictor of stone-free rate after PCNL than 2D stone burden measurements - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Stone burden has been reported as an independent predictor of post-operative outcomes of percutaneous nephrolithotomy (PCNL). We aimed to identify the optimal method of measurement of stone burden to predict residual stone at 3 months post percutaneous nephrolithotomy (PCNL).

#WCE2014 - Ellipsoid stone volume measured on computed tomography imaging correlates with computer generated 3D volumes - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Numerous CT-based parameters describing stone size have been reported to predict shockwave lithotripsy (SWL) success. Amongst these, stone volume has greatest predictive value. Widespread use of this metric is limited by the specialized software and expertise required for its determination. The majority of stones considered for SWL are ellipsoid in shape. Therefore, we hypothesize that the manually measured ellipsoid stone volume (ESV) can closely approximate the computer-generated stone volume (CSV).

#WCE2014 - The best choice and use of guide wires when buttressed during stenting or ureteroscopy - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: To overcome a large impacted stone that impedes passage of the guide wire we sometimes use a ureteric catheter to support the flexible tip of the wire. We compared four guide wires with regard to their tip bending force when buttressed at various distances from the tip.

#WCE2014 - Standardized analysis of laparoscopic and robot-assisted partial nephrectomy complications with Clavien classification - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: To analyze the complications according to the Clavien classification after laparoscopic partial nephrectomy (LPN) and Robotic-assisted partial nephrectomy (RPN).

#WCE2014 - Tumor multifocality was associated with poor prognosis in patients with upper urinary tract urothelial carcinoma after radical nephroureterectomy, irrespective of surgical procedure - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Upper urinary tract urothelial carcinoma (UTUC) accounts for approximately 5% in all urothelial tumors. While several independent risk factors have been reported, a potential prognostic variable would be the multifocality within the upper urinary tract. The aim of this study was to assess the impact of tumor multifocality for clinical outcomes in patients treated with RNU for UTUC.

#WCE2014 - A role of endourology in a treatment of urothelial cancer of upper urinary tract (UC-UUT) - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: A standard treatment for UC-UUT is/was open nephroureterectomy (NUE). Modern endourology gives many options to replace this approach. We assess a role of endourology in this topic.

#WCE2014 - In vitro comparison of different lithotrites regarding their efficacy of stone clearance - Interview

TAIPEI, TAIWAN (UroToday.com) - Introduction and Objectives: Several ultrasonic, pneumatic or electro-mechanical lithotrites are used during PCNL for fragmentation and removal of renal calculi. In an in vitro setup we compared different lithotrites or combinations (CyberWand/Olympus, Lithoclast Master/EMS, LUS2/Olympus, Lithobreaker/EMS) regarding their efficacy of lithotripsy and stone removal.

#WCE2014 - Ureteroscopy-assisted directional-eflow Doppler ultrasound-guided mini-endoscopic combined intrarenal surgery for the management of large renal stones - Interview
