OBJECTIVES: To study the feasibility and perioperative outcomes associated with a laparoscopic approach to completion nephrectomy in patients with locoregional disease recurrence after partial nephrectomy for renal cell carcinoma. PATIENTS AND METHODS: We performed a retrospective review of patients who underwent partial nephrectomy between 2006 and 2016 and developed locoregional recurrence, defined by the presence of new disease within the original surgical bed...

OBJECTIVE: To develop a contemporary complication profile for supracostal, upper pole endoscopic-guided prone tubeless "maxi-PCNL" in order to evaluate the need for change. MATERIALS/METHODS: We identified patients undergoing supracostal upper pole PCNL by a single surgeon at a high volume, tertiary care stone center between October 2010 and April 2017. Access was obtained with ureteroscopic guidance. The tract was dilated to 30 french via radial balloon dilation...

OBJECTIVE: To investigate by means of a randomized clinical trial the safety of no drain in the pelvic cavity after Robot-assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND). MATERIALS AND METHODS: From May to December 2016, 112 consecutive patients who underwent RARP with or without ePLND were prospectively randomized in a control (CG) and study (SG) group. In the CG, a drain was placed in the pelvic cavity at the end of surgery and removed after 24 hours...

INTRODUCTION: A novel semirigid ureterorenoscope named the Sotn ureterorenoscope was designed with a vacuum suction system. The present study aimed to evaluate the feasibility and safety of using the Sotn ureterorenoscope to manage single proximal ureteral or renal pelvis stones. METHODS: Data were retrospectively collected from consecutive patients treated with a Sotn ureterorenoscope between February 2010 and August 2015 at Sun Yat-sen Memorial Hospital of Sun Yat-sen University and Jiangmen Wuyi Traditional Chinese Medicine Hospital in China...

OBJECTIVES: To define the most suitable approach to assess residual stone fragments after RIRS. METHODS: Ninety two patients (115 renal units) submitted to RIRS for symptomatic kidney stones > 5 mm and < 20 mm or < 15 mm in the lower calyx diagnosed by noncontrast computed tomography (NCCT) were prospectively studied. Residual fragments were assessed by endoscopic evaluation (END) at the end of the procedure and by NCCT, ultrasound (US) and Kidneys-Ureter-Bladder X-ray (KUB) performed at the 90th postoperative-day (POD)...

INTRODUCTION: Laparoscopic surgery has been a standard procedure of living donor nephrectomy. Transperitoneal hand-assisted laparoscopic living donor nephrectomy (HALDN) has been commonly reported by many centers with excellent outcome. However, there are few studies reporting retroperitoneoscopic living donor nephrectomy (RPLDN). METHODS: Four hundred four consecutive kidney donors (124 men, 280 women) were enrolled in this study. Age of the donors was 55.0 ± 10...

PURPOSE: The holmium laser is used increasingly for a wide array of urological procedures. Laser safety goggles are mandatory at many centers for individuals within the nominal hazard zone, as set out by the institution. Recent ex-vivo studies suggest standard eye wear may be equally as protective. We sought to evaluate the perceptions and practice patterns of laser safety goggles in urology. MATERIAL AND METHODS: A 24 question survey was sent out via e-mail to an international email list of approximately 2000 urologists that were members of the Endourological Society...

INTRODUCTION: Morcellation of the adenoma after laser enucleation of the prostate (LEP) is both time consuming and prone to complications. We have designed a novel polyethylene sack (ProSac) to improve the morcellation process following LEP. A silicone and cadaver model were both utilized to evaluate safety and efficacy of the ProSac. METHODS: The inanimate model used tissue-mimicking silicone to accurately approximates bladder volume and compliance. The second model was developed using a fresh cadaver...

PURPOSE: Surgery for upper tract urinary stone disease is often reserved for symptomatic patients and those whose stone does not spontaneously pass after a trial of passage. Our objective was to determine whether payer type or race/ethnicity is associated with the timeliness of kidney stone surgery. MATERIALS AND METHODS: Population-based cohort study using the California Office of Statewide Health Planning and Development dataset from 2010 to 2012. We identified patients who were discharged from an emergency department with a stone diagnosis and who subsequently underwent a stone surgery...

OBJECTIVE: To determine associations between laboratory values and subsequent culture positivity in the acute ureteral calculi patient. Specifically, we aim to develop a predictive model to assist with optimization of patient outcomes and improvement of antimicrobial stewardship. METHODS: Utilizing the electronic medical record (EMR) system, we conducted a retrospective review of 3,888 patients with ureteral calculi. Relevant demographic information, vital signs and laboratory parameters obtained in the emergency department were tabulated...

This randomized study compared the clinical efficacy and safety of monopolar and bipolar electrosurgical modalities in transurethral resection of bladder tumor. Total 287 patients underwent transurethral resection of bladder tumor during the study period. After exclusion, 160 patients were analyzed in the study with 80 patients in either group. Demographic data such as age, gender distribution and co-morbidities were comparable between the groups. Tumor location, grade, stage and other tumor characteristics were also comparable between the groups...

OBJECTIVE: To identify avoidable predictors of postureteroscopy (URS) unplanned encounters and to minimize 30-day encounters. MATERIALS AND METHODS: We performed retrospective chart review and telephone surveys on patients who underwent URS for urolithiasis between January and June 2016. Univariate and multivariable analyses evaluated for potential predictors of unplanned encounters. RESULTS: Of 157 patients, there were 44 (28.0%) unplanned patient-initiated clinical phone calls, 23 (14...

INTRODUCTION: Moses technology is a novel Holmium:YAG laser system designed to minimize stone retropulsion and improve stone ablation when the laser is not in direct contact with the stone. Our aim was to assess the efficiency of Moses technology relative to short and long pulse lithotripsy using an automated in vitro "dusting model" of stone comminution. METHODS: All tests were conducted using a Lumenis Pulse 120H Holmium:YAG laser with a 365µm Moses D/F/L fiber...

Objective To evaluate the clinical value of endoscopic fibrin glue (FG) application therapy in treating hemorrhagic radiation cystitis (HRC). Patients and Methods This is a single cohort, prospective pilot study. We collected data from patients with HRC who were treated at our urology unit during the period May 2014 to December 2016. Patients with grade >=2 HRC for whom conventional therapy and trans-urethral endoscopic electrocoagulation had failed were treated with endoscopic intravesical FG. The mean follow-up was 26...

BACKGROUND AND PURPOSE: Although several different ureteral access sheaths (UASs) of ≤10/12F are commercially available, their advantages and disadvantages during retrograde intrarenal surgery (RIRS) are still unknown. This study aimed to evaluate the difference in intrapelvic pressure (IPP) between different UASs of ≤10/12F with several irrigation pressure settings. MATERIALS AND METHODS: Five different commercially available UASs (9.5/11.5F Flexor® , 10/12F ReTrace® , 10/12F Bi-Flex® , 10/12F Proxis® , and 10/12F UroPass® ) with the thinnest ureteroscope (UFR-P6® ) were tested with eight different irrigation pressures (40-180 mbar) in an ex vivo porcine kidney model...

Purpose To investigate the principles that govern ureteral stent failure by digitally and mechanically characterising their luminal reduction in response to various extrinsic compression forces. To explore the relationship between ureteral stent 'material area', 'luminal area' and 'cross-sectional area (CSA)' for resisting extrinsic compression forces. Materials and Methods 4.8 French (Fr, n=9), 6Fr (n=9), and 7Fr (n=9) ureteral stents were mechanically investigated to determine parameters that contribute to resisting radial compression forces...
