PURPOSE: Ureteroscopic laser lithotripsy requires irrigation for adequate visualization and temperature control during treatment of ureteral stones. However, there is 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 Ho:YAG laser while monitoring "intraureteral" temperature...

INTRODUCTION AND OBJECTIVES: Ureteral stent symptoms are experienced by the majority of patients with ureteral stents. No one stent or technology has shown a clear advantage.  The Helical<sup>TM</sup> stent, a spirally cut stent made of proprietary Percuflex<sup>TM</sup> material was designed to conform to the shape of the ureter and better accommodate patient movement.  We prospectively sought to compare unscheduled visits, analgesic use and pain scores in patients who received a Percuflex Helical ureteral stent following ureteroscopy compared to a historical control group...

We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus...

Purpose Nephrolithiasis contributes significantly to the world-wide health care 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. A search of both MEDLINE and EMBASE databases for randomized controlled trials (RCTs) in nephrolithiasis was performed to assess utilization of PROMs in these trials...

Background Given the high incidence, prevalence and rate of recurrence, urolithiasis stone treatment at a high stone-free rate should have a low complication rate. The German S2k guideline (GS2k-GL) for the diagnostic testing, therapy and metaphylaxis of urolithiasis provides recommendations for the first and second choice for stone treatment, depending on stone location and size. Ureterorenoscopy (URS) is the treatment of first choice for most stones. URS is only the second option for renal stones > 20 mm and proximal ureteric stones ≤ 10 mm...

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) is an effective treatment for renal stones. Due to the significant pain and morbidity after standard PCNL because of nephrostomy tubes, various modifications of PCNL are being performed. We report a randomized trial comparing these modalities. MATERIALS AND METHODS: A total of 75 patients were randomized into three groups of 25 each: standard PCNL with nephrostomy tubes (Group 1), tubeless PCNL with ureteric stent and no nephrostomy (Group 2), and totally tubeless PCNL without ureteric catheter or nephrostomy (Group 3)...

INTRODUCTION: It is generally advised to have a safety guidewire (SGW) present during ureteroscopy (URS) to manage possible complications. However, it increases the strenght needed to insert and retract the endoscope during the procedure, and, currently, there is a lack of solid data supporting the need for SGW in all procedures. We reviewed the literature about SGW utilization during URS. METHOD: A review of the literature was conducted through April 2017 using PubMed, Ovid, and The Cochrane Library databases to identify relevant studies...

OBJECTIVE: Extracorporeal shock wave lithotripsy (ESWL) represents one of the most frequently used methods to treat urinary tract calculi. However, sometimes we do not obtain the fragmentation expected. The aim of this study is to evaluate the parameters that may influence ESWL final results, developing a classification for better patient's selection and outcome optimization. METHODS: 270 patients with renal or ureteral stones were retrospectively reviewed after ESWL treatment, recording both clinical parameters (age, sex, location, laterality, body mass index [BMI]), and CT-Scan parameters (stone size and volume, skin-to-stone distance (SSD), mean and maximal stone density)...

INTRODUCTION: To determine rates of spontaneous ureteral stone passage in patients with indwelling ureteral stents, and to identify factors associated with the spontaneous passage of stones while a ureteral stent is in place. MATERIALS AND METHODS: From our institutional database, we identified patients who underwent ureteroscopic procedures for stone disease between January 1, 2013 and March 1, 2015. We compared the rates of spontaneous stone passage between patients who had previously undergone ureteral stent placement and those who had not...

Shows the current real time terminology and variants of systematization and grading of complications of contact ureteral lithotripsy (CULT). Research papers related to complications of CULT published over the last three decades were analyzed. Currently there is no clear terminology, classification, systematization and grading of CULT complications. The terms used are deficient because they do not adequately characterize specific complications of CULT. For example, some researchers define a complete ureteral avulsion as a defect at two levels, but others interpret it as a defect of the ureter at only one level...

RELEVANCE: Acute pyelonephritis is known to be the most complicated and severe urinary tract infection occurring in all age groups and accounting for 14% of all kidney diseases. The generally recognized standard antibiotic therapy cannot completely prevent the progression of the disease to its chronic form after relief of its acute manifestations thus leading to a high incidence of relapses. The aim of our study was to investigate the spectrum of uropathogens and their antibiotic sensitivity in acute obstructive pyelonephritis...

Urolithiasis can result as a complication of urinary diversión, favored by urinary stasis, intestinal mucus, urinary tract bacteriuria, the metabolic derangements and the presence of foreign bodies. We present a 52- year-old male who underwent radical cystectomy with construction of a Bricker uretero-ileostomy. 5 years later he was found with a forgotten ureteral stent, a 6 cm calculi occupying the whole ileal conduit and a 13 mm calculi in the left renal pelvis. We present our experience in the successful endourological management of an encrusted neglected ureteral stent in an ileal conduit, achieving a stone-free status without complications...
