Metabolic syndrome (MS) individuals have a higher risk of developing chronic kidney disease through unclear pathogenic mechanisms. MS has been also related with higher nephrolithiasis prevalence. To establish the influence of MS on renal function, we designed a murine model of combined metabolic syndrome and hyperoxaluria. Four groups of male Sprague-Dawley rats were established: (1) control group (n = 10) fed with standard chow; (2) stone former group (SF) (n = 10) fed with standard chow plus 0.75% ethylene glycol administered in the drinking water; (3) metabolic syndrome group (MS) (n = 10), fed with 60% fructose diet; (4) metabolic syndrome + stone former group (MS + SF) (n = 10), 60% fructose diet and 0...

The objective of this study is to investigate the efficacy of silodosin in medical expulsive therapy (MET) for ureteral stones. We conducted a systematic review and meta-analysis to determine the efficacy and safety of silodosin in MET for ureteral calculi. We searched PubMed, Embase, Medline, Central (the Cochrane Library, Issue 1,2013), Google Scholar from the inception to March 2015 for randomized controlled trials (RCTs), comparing silodosin with tamsulosin or control on ureteral stone passage. Eight RCTs with a total of 1145 ureteral stone patients (300 patients in the control group, 287 patients in the tamsulosin group, 558 patients in the silodosin group) were included in this meta-analysis...

Idiopathic calcium oxalate nephrolithiasis is a highly recurrent disease that is increasing in prevalence. Decades of research have not identified effective methods to consistently prevent the formation of nephroliths or induce medical dissolution. Idiopathic calcium oxalate nephroliths form in association with renal papillary subepithelial calcium phosphate deposits called Randall's plaques (RPs). Rodent models are commonly used to experimentally induce calcium oxalate crystal and stone formation, but a rodent model that conclusively forms RPs has not been identified...

PURPOSE: To compare the longitudinal health-related quality of life (HRQoL) after surgical intervention with ureteroscopic lithotripsy (URSL) and shock wave lithotripsy (SWL) and to evaluate the factors affecting HRQoL in urolithiasis patients. METHODS: A total of 262 patients who underwent lithotripsy (SWL, n = 61; URSL, n = 201) for upper urinary tract calculi treatment between June 2012 and January 2015 were evaluated. All patients were administered the Short-Form 36-item survey (SF-36) to assess HRQoL at four timepoints: before surgery, on the day of discharge, and 1 and 6 months after lithotripsy...

INTRODUCTION: Percutaneous nephrolithotomy (PNL) is the primary treatment modality for management of staghorn stones. PNL in supine position has important advantages over prone positon. However, studies comparing prone and supine positions for PNL in staghorn stone patients have conflicting results, and the aim of the current study was to compare prone and supine positions for PNL in staghorn stone cases. PATIENTS AND METHODS: Data of patients underwent PNL for staghorn stones in supine or prone position by a single urologist were collected prospectively...

Protein supplements are consumed for an expected increase in muscle mass and improved exercise performance, but as their impact on lithogenic parameters are unknown, we aimed to evaluate the effects of Whey protein (WP) and Albumin upon the risk factors for nephrolithiasis. WP or Albumin supplements (one scoop/day) were administered for 3 days to 18 healthy volunteers, with 1-week washout period between them. Serum and 24-h urine samples were collected at baseline and after completing each intervention. All participants were asked to replicate their baseline diet during the subsequent urine collection...

Numerous studies have reported an association between stress and urolithiasis. Although urinary risk factors have been measured in several of these, compelling evidence of a causal relationship has not been established. A shortcoming is that alterations in single urinary parameters rather than ratios and quotients, which provide a more synergistic risk evaluation, have been measured. Recently, we speculated about a possible association between chronic stress and stone recurrence. This presents an intriguing dichotomy of whether stress causes stones or vice versa, or whether they are linked in a self-propagating stress-stones-stress-recurrence cycle...

Many urine proteins are found in calcium oxalate stones, yet decades of research have failed to define the role of urine proteins in stone formation. This urine proteomic study compares the relative amounts of abundant urine proteins between idiopathic calcium oxalate stone forming and non-stone forming (normal) cohorts to identify differences that might correlate with disease. Random mid-morning urine samples were collected following informed consent from 25 stone formers and 14 normal individuals. Proteins were isolated from urine using ultrafiltration...

The rates of extracorporeal shock wave lithotripsy (SWL) appear stable in the UK. However, there is little evidence on the natural history of these calculi if SWL fails. We set to look at the effectiveness of SWL in patients with a single, previously untreated renal stone and the natural history of those stones that failed treatment. We retrospectively reviewed all data from our prospectively collected database of patients undergoing a first treatment for a single renal stone between October 2010 and November 2013...

Ketamine, as a systemic and local analgesic, has been used to reduce postoperative pain in many studies. The present study was designed to assess the analgesic efficacy of nephrostomy tract infiltration of ketamine in postoperative pain after tubeless percutaneous nephrolithotomy (PCNL). Sixty-six patients with renal stone who were candidates for PCNL were randomized to two groups with 33 patients in each group. In group K, 20 mL saline solution containing 1.5 mg/kg ketamine was infiltrated into the nephrostomy tract and in group C, 20 mL saline solution was infiltrated into the nephrostomy tract at the end of surgery...

Kidney stones are increasing in the pediatric and adult populations; similarly osteoporosis is increasingly recognized in children. While kidney stone formers are known to suffer from low bone density, metabolic bone patients have not been considered a high risk population for kidney stones. Retrospective chart review of Nationwide Children's Hospital Metabolic Bone Clinic patients from October 2009-2013. Patients were identified by ICD 9 codes for osteoporosis, osteopenia, low bone density and kidney stones...

We previously developed an animal model of calcium oxalate (CaOx) deposition on the Malphigian tubules of Drosophila melanogaster as a model of urolithiasis. Here, we introduce a new tool for the study of anatomical structure for Drosophila. As a consequence of technical development, the invention of micro-computerized tomography (CT) has been introduced to the small animal, such as rat and mice. We used Drosophila as a model organism and fed the flies 0.5% lithogenic agent ethylene glycol for 3 weeks. Samples were simply prepared for further scanned by micro-CT to scan samples at 800 nm resolution...

The aim of this study was to estimate uric acid renal stone prevalence rates of adults in different countries of the world. PubMed was searched for papers dealing with "urinary calculi and prevalence or composition" for the period from January 1996 to June 2016. Alternative searches were made to collect further information on specific topics. The prevalence rate of uric acid stones was computed by the general renal stone prevalence rate and the frequency of uric acid stones in each country. After the initial search, 2180 papers were extracted...

The aim of this study was to compare the clinical characteristics of "pure" uric acid renal stone formers (UA-RSFs) with that of mixed uric acid/calcium oxalate stone formers (UC-RSFs) and to identify which urinary and dietary risk factors predispose to their formation. A total of 136 UA-RSFs and 115 UC-RSFs were extracted from our database of renal stone formers. A control group of 60 subjects without history of renal stones was considered for comparison. Data from serum chemistries, 24-h urine collections and 24-h dietary recalls were considered...
