OBJECTIVE: The increasing number of flexible ureterorenoscopy (fURS) procedures, the fragility of devices, and their growing maintenance and repair costs represent a substantial burden for urologic departments. Disposable single-use fURS devices offer many advantages over reusable fURS. Among them, the LithoVue™ model shows the best clinical utility. In our study, we assessed the economic aspects of reusable fURS application compared with the potential costs and benefits of single-use fURS (LithoVue™)...

OBJECTIVES: The aim of this study was to investigate "caliceal" fluid temperature changes during holmium laser activation/lithotripsy using settings up to 40 W power output with different irrigation flow rates. MATERIALS AND METHODS: The experimental system consisted of a glass test tube (diameter 10 mm/length 75 mm) filled with deionized water, to mimic a calix. Real-time temperature was recorded using a thermocouple (Physitemp, NJ) positioned 5 mm from the bottom of the tube...

INTRODUCTION: The management of residual fragments (RFs) that persist after percutaneous nephrolithotomy (PCNL) has been poorly studied. Fragments have the potential to grow or cause symptoms. The aim of this study was to follow patients with fragments after PCNL to identify predictors of stone-related events (re-interventions and complications) after PCNL. PATIENTS AND METHODS: Data were retrospectively collected from patients who underwent surgery from 2008 to 2013 at our hospital...

INTRODUCTION: Kidney stone risk factors are understudied among Asians. Our study objective was to investigate associations of obesity and other chronic diseases with incident kidney stones among the urban Chinese. PATIENTS AND METHODS: Included in this study are two prospective cohorts: the Shanghai Women's Health Study (N = 69,166) and Shanghai Men's Health Study (N = 58,054). Incident kidney stones were determined by self-report in 2004 and 2008. Cox regression models were used to evaluate the associations of study variables with stone risk with adjustment of demographics, medical history, and dietary intakes...

PURPOSE: Ureteroscopic laser lithotripsy requires irrigation for adequate visualization and temperature control during treatment of ureteral stones. However, there are little data on how different irrigation and laser settings affect the ureteral wall and surrounding tissues. This effect has become an important consideration with the advent of high-powered lasers. We therefore evaluated the effect of laser settings and irrigation flow on ureteral temperature in an in vitro setting. MATERIALS AND METHODS: To mimic ureteroscopic laser lithotripsy, we simulated clinically relevant irrigation flow rates and fired a Holmium:Yttrium-aluminum-garnet (Ho:YAG) laser while monitoring "intraureteral" temperature...

PURPOSE: To evaluate the efficacy and safety of increasing the energy dose in treating urinary lithiasis with extracorporeal lithotripsy through an expanded number of Shock Waves Per Session (SWPS). MATERIALS AND METHODS: a randomized, prospective, and comparative study was performed with patients with renal or ureteral lithiasis from 2011 to 2014. Two groups were studied: Group A (n = 136), treated with 3500 SWPS, and Group B (n = 171), subjected to an expanded treatment with 7000 SWPS...

The manuscript by Matlaga et al titled "Ureteroscopic Laser Lithotripsy: A Review of Dusting Versus Fragmentation With Extraction" was first intended for a meta-analysis publication, but because limited data published, it became an interesting review article focused in the current debate about which of the so described laser urinary lithotripsy "Fragmentation with Extraction" and "Dusting" techniques is better. Authors do an effort to homologize terminology and nomenclature and list the most efficient energy settings used in clinical scenario on the "Fragmentation with Extraction" [(Frequency 12-15 Hz (< 30 watt laser) >50Hz (100/120 watt laser) / Energy 0...

PURPOSE: Nephrolithiasis contributes significantly to the worldwide healthcare burden. Patient-reported outcome measures (PROMs) are widely recognized as important outcome measures for patient-centered care. We sought to summarize what is currently known about PROMs in urinary stone disease and to characterize use of PROMs in randomized controlled trials (RCTs) for nephrolithiasis. MATERIALS AND METHODS: Health-related quality of life (HRQOL) in patients with nephrolithiasis is reviewed...

Port placement for robot-assisted laparoscopic urologic surgery can be critical to effective completion of the minimally invasive procedure. An ideal port template would allow unhampered access to all critical structures during surgery, easy access for the bedside assistant, and minimization of arm collision with the fewest ports necessary to minimize cosmetic impact. We present a comprehensive plan for the placement of ports across different procedures for a variety of upper tract (radical/partial nephrectomy, retroperitoneal radical/partial nephrectomy, and pyeloplasty), lower tract (prostatectomy, and cystectomy), combined upper/lower tract (nephroureterectomy, retroperitoneal lymph node dissection), and female pelvic surgeries...

INTRODUCTION AND OBJECTIVES: In recent years, there has been a shift to minimally invasive partial nephrectomy (MIPN) with the dissemination of robotic-assisted technology. However, contemporary data on the comparative morbidity of open PN and MIPN are lacking. We therefore evaluated the perioperative morbidity of MIPN and OPN using a contemporary national cohort. METHODS: We identified 13,658 patients aged 18-89 who underwent PN from 2010-2015 in the National Surgical Quality Improvement Program (NSQIP) database, of whom 9,018 (66...

OBJECTIVE: Urinary incontinence is one of the most bothersome adversities after robot-assisted radical prostatectomy (RARP). The aim of this study was to investigate the urinary continence recovery and the effect of various surgical techniques. MATERIALS AND METHODS: We previously reported that posterior rhabdosphincter reconstruction and nerve-sparing were independent predictors of urinary continence recovery 1 month after catheter removal in 199 patients who underwent RARP...

INTRODUCTION: Single-use ureteroscopes have been gaining popularity in recent years. We compare the optics, deflection, and irrigation flow of two novel single-use flexible ureteroscopes-the YC-FR-A and the NeoFlex-with contemporary reusable and single-use flexible ureteroscopes. METHODS: Five flexible ureteroscopes, YC-FR-A (YouCare Tech, China), NeoFlex (Neoscope, Inc., USA), LithoVue (Boston Scientific, USA), Flex-Xc (Karl Storz, Germany), and Cobra (Richard Wolf, Germany), were assessed in vitro for image resolution, distortion, field of view, depth of field, color representation, and grayscale imaging...
