OBJECTIVE: To assess the feasibility of laparoscopic nephrectomy (LN) in the treatment of patients with xanthogranulomatous pyelonephritis (XGP). METHODS: Retrospective study of 17 patients (mean age 60.0±13.3 years) who underwent LN by a single surgeon from 2010-2018. Socio-demographic and clinical data including diagnosis, presenting clinical features, surgical management and postoperative course were analyzed. RESULTS: LN was successfully performed in 15 (88...

INTRODUCTION: staging of upper tract urothelial carcinoma remains a dilemma due to imaging and biopsy limitations leading to understaging. We seek to determine the accuracy of endoluminal ultrasound (ELUS) for clinical staging of UTUC. MATERIALS AND METHODS: Patients evaluated for UTUC underwent retrograde pyelography, ureteroscopy and ELUS. ELUS was performed using mechanical radial scanning at 20 MHz in B-mode with a 5F probe. Cine clips were evaluated by 2 radiologists blinded to ureteroscopic and pathology findings...

BACKGROUND: Due to new radiobiologic data, the International Commission on Radiological Protection recommends a dose limit of 20 mSv per year to the eye lens. Therefore, the IAEA International Basic Safety Standard and the European council directive 2013/59/EURATOM require a reduction of the annual dose limit from 150 to 20 mSv. Urologists are exposed to an elevated radiation exposure in the head region during fluoroscopic interventions, due to the commonly used overtable X-ray tubes and the rarely used radiation protection for the head...

INTRODUCTION: With increasing use of high-power laser settings for lithotripsy, the potential exists to induce thermal tissue damage. In vitro studies have demonstrated that temperature elevation sufficient to cause thermal tissue damage can occur with certain laser and irrigation settings. The objective of this pilot study was to measure caliceal fluid temperature during high-power laser lithotripsy in an in vivo porcine model. METHODS: Four female pigs (30-35 kg) were placed under general anesthesia and positioned supine...

INTRODUCTION: CT is the gold standard for visualizing renal and ureteral calculi. CT three-dimensional reformatting allows for automatic, accurate, and reliable measurement of stone size, volume, density, and location. In this study, we aimed to develop and test a software platform capable of calculating a battery of clinically important urinary stone parameters at the point-of-care (POC). METHODS: The syngo Calcium Scoring (Siemens Corporation) algorithm was modified to identify calcium-based stones using an attenuation threshold (250 HU) within a region of interest...

OBJECTIVES: To report a comparative analysis of outcomes in patients who underwent excisions of renal hilar tumors using both open and robotic approaches. MATERIALS AND METHODS: We retrospectively reviewed robotic and open patients who underwent partial nephrectomy (PN) of renal hilar tumors between 2011 and 2016. "Trifecta" was defined as negative surgical margins, no complications, and a GFR preservation of >90% at last follow-up. Inverse probability of treatment weighting (IPTW) was applied to equilibrate treatment groups, minimize selection bias, and optimize inference on the basis of each patient's clinico-demographic characteristics...

INTRODUCTION: The Endockscope combines a smartphone, a battery powered flashlight and a fiberoptic cystoscope allowing for mobile videocystoscopy. We compared conventional videocystoscopy with the Endockscope paired with next generation smartphones in an ex-vivo porcine bladder to evaluate its image quality. MATERIALS AND METHODS: The Endockscope consists of a three-dimensional (3D) printed attachment that connects a smartphone to a flexible fiberoptic cystoscope plus a 1000 lumen light-emitting diode (LED) cordless light source...

Objective To perform evaluation of the perioperative outcomes and 90 day complication rates of continuation of low dose aspirin through surgery in patients undergoing robot assisted radical prostatectomy (RARP). A significant proportion of patients undergoing RARP are on antiplatelet medications for primary or secondary prevention of cardiovascular events. However, there is still a relative lack of data with regards to the advantages and complications of continuing these medications through surgery. Methods Our usual protocol of RARP entails continuation of low dose aspirin (75 mg once a day) for patients who are already on antiplatelet agents...

INTRODUCTION: We surveyed United States of America (U.S.A.)-based urologists to characterize practice patterns and indications to perform a renal mass biopsy for small renal masses. MATERIALS AND METHODS: Members of the American Urological Association who practice in the United States were invited to participate in an 11-question web-based survey that was distributed via SurveyMonkey® from December 2016 to January 2017. RESULTS: There were 1,131 respondents...

Introduction A "Negative" ureteroscopy (URS) is defined as a URS in which no stone is found during the procedure. It may occur when the stone has already been passed spontaneously or when it is located outside the collecting system. The aim of the study was to outline risk factors for Negative-URS. Material and Methods We retrospectively analyzed the possible risk factors for Negative-URS from a database of 341 URS cases. In every case where presumptive ureteral stone was not found, a formal nephroscopy as well as a whole collecting system revision were completed...

Background Laparoscopy is widely used in the urological field. This systematic review and meta-analysis were conducted to assess the clinical and surgical efficacy of three-dimensional (3D) laparoscopic system in comparison with two-dimensional (2D) laparoscopy for the treatment of different urological conditions. Methods Following PRISMA guidelines, a systematic literature search from Web of Science, PubMed, Cochrane Library, and EMBase was carried out to identify relevant studies published up to May 2018...

OBJECTIVES: Urine cultures before secondary ureterorenoscopy (URS) are recommended to exclude bacteriuria, but results are often pending on the day of surgery. We sought to develop predictive models that reliably indicate the absence of bacteriuria in patients with indwelling ureteral stents based on readily available data. PATIENTS AND METHODS: Records of patients undergoing secondary URS between 2014 and 2017 were assessed retrospectively. Patient characteristics, automated urinary sediment analysis, blood analyses, and results of urine cultures were analyzed using descriptive statistics, receiver operating characteristic curves, logistic regression, and model selection...

PURPOSE: To present the positive impact of technique standardization on successful outcome, fluoroscopy, and total operating time (TOT) shortening in a prospective study. METHODS: Six experienced endourologists participated. To assess whether the adaptation of standardized surgical steps improved their methodology with time, 253 patients were prospectively divided in three consecutive 1-month groups. Patients underwent stent placement and exchange and total operating and fluoroscopy times (FTs) were recorded...
