INTRODUCTION: There is limited, yet compelling evidence supporting the role of surgeon technical performance in influencing patient outcomes. To date, this concept has been underexplored in endourologic procedures. We hypothesized that a surgeon's technical performance plays a role in predicting an early return to continence after robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS: We conducted a retrospective, matched case-control analysis of prospectively collected unedited RARP endoscopic videos performed by a single surgeon...

PURPOSE: In the first-in-human trial of ultrasonic propulsion, subjects passed collections of residual stone fragments repositioned with a C5-2 probe. Here, effectiveness and safety in moving multiple fragments are compared between the C5-2 and a custom (SC-50) probe that produces a longer focal beam and burst duration. MATERIALS AND METHODS: Effectiveness was quantified by the number of stones expelled from a calyx phantom consisting of a 30-mm deep, water-filled well in a block of tissue mimicking material...

INTRODUCTION:  Immediate ureteroscopic treatment for patients presenting to the emergency room with symptomatic ureterolithiasis is more commonly being utilized. Recent reports demonstrate good efficacy for emergency URS, however preoperative predictors of treatment success have not been described. Here, we report our multi-center experience with emergency URS and identify predictors of successful treatment. We also describe the Emergency Ureteral Stone Treatment (EUST) Score, which integrates these predictors and stratifies patients into those that are likely and unlikely to have successful treatment...

OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is a well-established procedure for the management of urinary calculi and can be performed intercostally or subcostally. Favoring one approach vs the other is still debatable, and literature has been inconclusive regarding the efficacy and safety of both approaches. Hence, this study aims to assess the safety and efficacy of direct non-angled intercostal technique performed under full expiration and to compare it to the subcostal approach...

INTRODUCTION: Fluoroscopy is widely used during endourologic procedures and is associated with treatment required radiation exposure. Our objective was to estimate patient radiation exposure during fluoroscopy with either a fixed table or portable C-arm using a validated anthropomorphic adult male model. MATERIALS AND METHODS: A validated male anthropomorphic model was placed supine on both a cystoscopy operating room table and a fixed fluoroscopy table unit. Metal oxide semiconductor field effect transistor dosimeters were placed at 20 organ-specific locations in the model to measure organ specific dosages...

BACKGROUND AND PURPOSE: Modern flexible ureteroscopes (fURSs) have good deflection, but despite this, approaching an acute angled calix can still be difficult. The goals of our in vitro study were to assess the ability of the available modern fURSs to effectively access the sharp angled calices and to compare the end-tip deflection of the various fiber-optic and digital fURSs. MATERIALS AND METHODS: Using a bench-training model for FURS (K-Box, Porgès-Coloplast), we tried to access an acute angled calix with nine different fURSs (BOA vision, COBRA vision, R...

INTRODUCTION: Management of pediatric stone disease is challenging, with standard percutaneous nephrolithotomy (PCNL) having a good stone-free rate (SFR), but with associated high complication rates. Miniaturization of this technique has led to the rise of minimally invasive PCNL techniques such as micro (<10F) and ultra-mini (<15F) PCNL procedures. Our objective was to perform a systematic review of the literature to evaluate the success and complication rates of minimally invasive PCNL techniques in the pediatric age group (<18 years)...

OBJECTIVE: Vascular calcifications are associated with nephrolithiasis. While studies have demonstrated correlations with vascular disease and calcium stones in kidney stone formers (KSF), an etiologic link has remained elusive. As a non-contrast CT scan (NCCT) is typically part of a stone evaluation, our objective was to evaluate the association of NCCT-based assessment of abdominal aortic calcifications (AAC) with 24-hour urine parameters and stone composition. MATERIALS AND METHODS: 97 KSF were included with CT imaging and 24-hour urine studies...

INTRODUCTION: Ureteral stenting is a common procedure in urology. The cystoscopic removal of Double-J stents (DJ) causes unpleasant side effects with a negative impact on patient's quality of life. The aim of our study was to evaluate this newly developed magnetic DJ and compare it with a standard DJ regarding quality of life with indwelling DJs as well as discomfort during the removal. MATERIAL AND METHODS: The magnetic DJ (Blackstar, Urotech [Achenmühle, Germany]) is a standard 7F ureteral stent with a small magnetic cube fixed through a string on the loop of the distal part of the stent...

Introduction Irreversible electroporation (IRE) is a non-thermal minimally invasive technique to treat small renal masses (SRM). Prior work has demonstrated greater narcotic requirements after radiofrequency ablation (RFA) for tumors closer to body-wall musculature. We hypothesized that pain after IRE is not dependent on tumor location due to the athermal mechanistic action. Methods Retrospective review of 50 consecutive percutaneous IRE and RFA cases was performed from 2013 to 2014. Eight patients were excluded from analysis due to incomplete anesthesia record and/or multiple ablations per session leaving 21 patients in each group...

INTRODUCTION AND OBJECTIVE: Prostatic urethral lift (PUL) is gaining popularity for the treatment of symptomatic benign prostatic hyperplasia (BPH). We describe the feasibility and considerations of performing holmium laser enucleation of the prostate (HoLEP) as a salvage therapy after previous PUL. METHODS: Men who have undergone HoLEP after PUL were retrospectively identified from three institutions with surgeons experienced in HoLEP. Subjects were characterized by age, time from PUL procedure (months) to HoLEP surgery, indication for retreatment, and pre-operative prostate volume by ultrasound...

INTRODUCTION: Understanding the factors affecting success of extracorporeal shockwave lithotripsy (SWL) would improve informed decision-making on the most appropriate treatment modality for an individual patient. Although stone size and skin-to-stone distance do correlate with fragmentation efficacy, it has been shown that stone composition and architecture, as reflected by structural heterogeneity on CT, are also important factors. This study aims to determine if CT texture analysis (CTTA), a novel, nondestructive, and objective tool that generates statistical metrics reflecting stone heterogeneity, could have utility in predicting likelihood of SWL success...

INTRODUCTION: Determining if bacterial presence on urine microscopy represents clinical infection is important as urinary drainage is indicated in patients with obstructing urolithiasis and concomitant urinary tract infection. We aim to investigate if the presence of bacteria on urine microscopy is associated with markers of infection in patients with obstructing urolithiasis presenting to the emergency room. METHODS: A cross-sectional study was performed on 199 patients with obstructing urolithiasis divided into two groups according to the presence of bacteria on urine microscopy...
