INTRODUCTION: We set out to investigate whether general anesthesia with low ventilation (LV, respiratory rate ≤8/min and tidal volume <500 ml) could reduce renal mobility and thereby facilitate improved retrograde intrarenal surgery (RIRS) compared to general anesthesia with standard ventilation (SV). MATERIALS AND METHODS: All 60 consecutive patients who presented for RIRS in our department from September 1, 2017 to December 31, 2017 were prospectively randomized 1:1 into one group that was selected to receive SV and another that received LV...

OBJECTIVES: To report a comparative analysis of outcomes in patients who underwent multiple excisions for unilateral, synchronous, multifocal renal tumors using both open and robotic approaches. METHODS: We retrospectively reviewed 110 patients who underwent robotic and open partial nephrectomy and had multiple tumor excisions in an ipsilateral kidney. "Trifecta" was defined as negative surgical margins, no urologic complications, and a GFR preservation of >90% at last follow-up...

PURPOSE: Endourologic procedures like percutaneous nephrolithotomy (PCNL) employ the use of foot pedals in low-light operating room (OR) settings. These pedals can be especially difficult to locate or distinguish when several pedals are present during a single operation. Improper instrument activation in the OR has led to serious complications ranging from unintentional electrocautery to patient burns and even an intraoperative explosion. This study evaluates the impact of color-coded illumination on speed and efficiency of foot pedal activation...

OBJECTIVES: To test rates over time of robotic partial and radical nephrectomy (RPN and RRN) at teaching vs. non-teaching institutions and to examine associated complication rates and length of stay. MATERIAL AND METHODS: Within the Nationwide Inpatient Sample (2008-2013), after stratification according to institutional teaching status, we examined the rates of robotic, open and laparoscopic PN and RN. Subsequently, we tested complication rates and length of stay associated with RPN or RRN according to institutional teaching status...

OBJECTIVE: The increasing number of flexible ureteroscopy (fURS) procedures, the fragility of devices and their growing repair costs represent a substantial burden for urological departments worldwide. No risk factors of flexible ureteroscope damage have been identified so far. The objective of this study was to investigate the impact of infundibulopelvic angle (IPA) on device damage and on other intra- and postoperative factors such as length of hospital stay (LOS), surgical complications, stone-free rate (SFR), operation and fluoroscopy time...

INTRODUCTION: Advances in flexible ureteroscope design and accessory instrumentation have allowed for more challenging cases to be treated ureteroscopically. Here we evaluate our experience with ureteroscopy for the management of large renal calculi (≥ 2cm) and provide a concise review of recent reports.. METHODS: A retrospective review was undertaken of all ureteroscopy cases between 2004 and 2014 performed by the endourologic team at a single academic tertiary care institution...

OBJECTIVE: To compare perioperative 30-day outcomes between minimally-invasive radical prostatectomy (MIRP) with and without concurrent inguinal hernia repair (IHR) using a national database. METHODS: The National Surgical Quality Improvement Program database was queried for MIRP from 2012-2015. Concurrent IHR was identified using relevant Current Procedural Terminology codes. Primary outcomes were overall complications, reoperations, unplanned readmissions, and mortality within 30 days of MIRP...

OBJECTIVE: To evaluate a portable electronic pH meter and to put its accuracy in perspective with reagent strips read by a layperson, a healthcare professional and an electronic reading device. MATERIALS AND METHODS: Based on a pre-analysis on 20 patients, a sample size of 77 urine aliquots from healthy volunteers was necessary to obtain sufficient study power. Measurements of urinary pH were obtained by use of reagent strips, a portable pH meter and a laboratory pH meter (gold standard)...

Objective To investigate the correlation between fluid dynamic processes and deposition of encrusting particles in ureteric stents. Materials and Methods Microfluidic models (referred to as 'stent-on-chip' or SOC) were developed to replicate relevant hydrodynamic regions of a stented ureter, including drainage holes and the cavity formed by a ureteric obstruction. Computational fluid dynamic (CFD) simulations were performed to determine the wall shear stress (WSS) field over the solid surfaces of the model, and the computational flow field was validated experimentally...

INTRODUCTION: To make percutaneous access easier in PCNL, we developed Automated Needle Targeting with X-ray (ANT-X) Method: ANT-X uses an image registration software with a closed loop feedback system to autoalign the puncture needle to the desired calyx using the bullseye technique. We tried percutaneous punctures on a live pig model and compared the results with free-hand technique. We then performed our first PCNL in a human subject with the aid of ANT-X. Our patient was a 48 year-old gentleman with a 1...

Objective The objective of this meta-analysis was to compare the efficacy and safety of externalized ureteral catheter (EUC) and double-J stent (DJS) in tubeless percutaneous nephrolithotomy (PCNL) for patients with upper urinary stones based on published literature. Materials and Methods A comprehensive literature search using Pubmed, Embase, and Cochrane Library was performed to find studies comparing outcomes of EUC and DJS for treating patients with upper urinary stones up to Dec 2017. 7 studies, which included 863 patients from 5 randomized controlled trials(RCTs) and 2 non-RCTs published between 2009 and 2017, met our inclusion criteria and were included in this systematic review and meta-analysis...

OBJECTIVES: To compare the outcomes of retroperitoneal versus transperitoneal approach for robot assisted partial nephrectomy (RAPN). MATERIALS AND METHODS: A systematic review of the literature was performed through January 2018 using PubMed, Scopus, and Ovid databases. Article selection proceeded according to the search strategy based on PRISMA criteria. Only studies comparing retroperitoneal to transperitoneal approach for RAPN were deemed eligible for inclusion...

BACKGROUND AND PURPOSE: Temporary drainage of the upper urinary tract after ureterorenoscopy for the treatment of urinary stones is almost a routine in endourologic practice. In these cases, a Double-J stent (DJS) is left for 7 or more days. In borderline cases, a ureteral catheter attached to the urethral catheter may be left for 24-48 hours. In some situations, tubeless approach is possible. The purpose of this study was to evaluate the necessity and immediate postoperative implications of upper tract drainage by comparing complications and symptoms at the immediate postoperative period in these three groups of patients...
