Ureteroscopy flexible

Ben H Chew, Dirk Lange
Open ureterolithotomy and pyelolithotomy used to be first line therapy for treating kidney and ureteral stones. With the advent of shockwave lithotripsy, open stone surgery became less prevalent, but once ureteroscopy became more prevalent, open stone surgery became all but extinct. Advances in smaller, more flexible endoscopes and improvements in intracorporeal lithotripters, ureteroscopy has become a mainstay of therapy for kidney stones. The holmium:YAG laser can be utilized through flexible instruments and fragments any stone no matter what it is composed of...

PURPOSE: Questions still remain regarding the durability and longevity of flexible ureteroscopes (URS). The objective of this manuscript is to estimate potential economic benefits of the single use flexible digital URS compared to our recent experience with reusable flexible digital URS using cost benefit analysis. MATERIALS AND METHODS: Ureteroscopic procedures were prospectively recorded over a 12-month period (February 2014 - February 2015). All flexible ureteroscopies were performed using the Karl Storz Flex-XC™ digital ureteroscopes...

INTRODUCTION: We evaluated a new digital single-use flexible ureteroscope, LithoVue™ with respect to deflection, image quality and maneuverability. METHODS: A prospective cohort study was conducted in eight tertiary reference centers in Europe in December 2015 and January 2016. All consecutive patients included underwent flexible ureteroscopy and were 18 years or older. Deflection and image quality pre- and post-use and maneuverability were rated with a Likert scale...

We evaluated the clinical value of flexible ureteroscopic lithotripsy for the treatment of upper urinary tract calculi in infants. Fifty-five infants with upper urinary tract calculi were included in this study: 41 males and 14 females. Retrograde intrarenal surgery was performed by an 8 Fr/30 cm flexible ureterorenoscope (POLY®) combined with a holmium laser. CT scanning or radiography of the kidneys, ureters, and bladder region was performed one month after the operation to confirm the clearance of calculi...

BACKGROUND: The challenges of training and assessing endourologic skill have driven the development of new training systems. The Center for Research in Education and Simulation Technologies (CREST) has developed a team and a methodology to facilitate this development process. METHODS: Backwards design principles were applied. A panel of experts first defined desired clinical and educational outcomes. Outcomes were subsequently linked to learning objectives. Gross task deconstruction was performed and the primary domain was classified as primarily involving decision-making, psychomotor skill or communication...

BACKGROUND: We analyzed the outcome and complications of rigid (R-URS) and flexible (F-URS) ureteroscopic lithotripsy for treatment of proximal ureteric stone (PUS). SUBJECTS AND METHODS: Retrospective data of 135 patients (93 males and 42 females) submitted to R-URS and F-URS for treatment of PUS in the period between July 2013 and January 2015 were investigated. (R-URS, group 1) was performed in 72 patients while 63 patients underwent (F-URS, group 2).We compared the 2 groups for success, stone characteristics, operative time, intraoperative and postoperative complications...

INTRODUCTION: Roboflex Avicenna represents a new device for flexible ureteroscopy, able to provide an efficient lithotripsy for renal calculi, Bucharest being the fourth place in the world where such a device is already in use. MATERIAL AND METHODS: The study was prospective and included a number of 132 patients equally randomized which underwent standard flexible ureteroscopy and robotic flexible ureteroscopy for renal calculi between July and February 2016. All the procedures were performed with aStorz XC flexible ureteroscope in association with Avicenna Roboflex...

PURPOSE: To evaluate the factors affecting complication rates of flexible ureteroscopy and laser lithotripsy (FURSL). MATERIALS AND METHODS: Data on a total of 1395 patients, with 1411 renal units underwent 1571 procedures with FURSL for renal and/or proximal ureteral stones between April 2012 and January 2016, were retrospectively analyzed. Complications were assessed using the Satava and modified Clavien systems. Univariate and multivariate analyses were done to determine predictive factors affecting complication rates...

Ureteral polyps are benign tumors of the ureter, which are relatively rare. The etiology has proposed various hypotheses, involving chronic inflammation and congenital disease. Most of them are commonly diagnosed in the upper ureter including the ureteropelvic junction. Some studies have reported polypectomy using a holmium laser, but several studies presented laparoscopic ureteroureterostomy for patients in whom the mentioned procedure is difficult. We underwent laparoscopic ureteroureterostomy with a combination of flexible ureteroscope for ureteral polyps of more than 3 cm length...

BACKGROUND: Since the development of the first flexible ureteroscope, in 1964, technological advances in image quality, flexibility, and deflection have led to the development of the first single-use digital flexible ureteroscope, LithoVue™ (Boston Scientific, Marlborough, MA). With respect to reusable fiber-optic and now digital ureteroscopes, there is an initial capital cost of several thousand dollars (USD) as well as, controversy regarding durability, the cost of repairs and the burdensome reprocessing steps of ureteroscopy...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is the most widely recommended treatment for calyceal diverticular calculi, providing excellent stone-free results. However, its invasiveness is not negligible considering its major complication rates. Flexible ureteroscopy (FURS) is currently used to treat calyceal diverticula. However, the greatest drawback of FURS is locating the diverticulum since its neck is narrow and concealed. In such a case, the FURS procedure must be converted to PCNL...

INTRODUCTION: In special situations such as malrotated or ectopic kidneys and UPJ stenosis treatment of renal lithiasis can be challenging. In these rare cases laparoscopy can be indicated. OBJECTIVE: Describe the Laparoscopic-assisted rigid nephroscopy performed via transpyelic approach and report the feasibility. PATIENTS AND METHODS: We present two cases of caliceal lithiasis. The first is a patient that ESWL and previous percutaneous lithotripsy have failed, with pelvic kidney where laparoscopic dissection of renal pelvis was carried out followed by nephroscopy utilizing the 30 Fr rigid nephroscope to remove the calculus...

BACKGROUND: Flexible ureteroscopic lithotripsy (URS) is rapidly becoming a first-line therapy for patients with renal and ureteral calculi. Most current medical infusion devices can only monitor infusion flow and pressure, but not renal pelvic pressure (RPP). PATIENTS AND METHODS: We designed a patented intelligent system to facilitate flexible URS that included an irrigation and suctioning platform and a ureteral access sheath (UAS) with a pressure-sensitive tip, enabling regulation of the infusion flow precisely and control of the vacuum suctioning by computerized real-time recording and monitoring of RPP...

OBJECTIVE: To assess and compare the applicability of the Resorlu-Unsal Stone Score (RUSS) and the Modified Seoul National University Renal Stone Complexity (S-ReSC) score for flexible ureterorenoscopy (f-URS). PATIENTS AND METHODS: We retrospectively analyzed the hospital files of 719 patients who had been treated with f-URS for kidney stone at two referral centers between July 2012 and December 2015. The RUSS and Modified S-ReSC scores were calculated by the same surgeon for each patient using imaging methods and were compared as to their predictive capability for postoperative success...
