Fatty acid (FA) composition of phospholipids in plasma and red blood cells (RBC) can influence calciuria, oxaluria and renal stone formation. In this regard, the ratio of arachidonic acid (AA) and its precursor linoleic acid (LA) appears to be important. Administration of γ-linolenic acid (GLA) has been shown to increase the concentration of dihomo-gamma linoleic acid (DGLA) relative to AA indicating that it may attenuate biosynthesis of the latter. Such effects have not been investigated in race groups having difference stone occurrence rates...

The purpose of the study was to present our experience of retaining encrusted ureteral stents (EUS) and discuss the effectiveness of 4.5/6.5F ureteroscope (URS) in the procedure. The data of patients with EUS in our center from January 2012 to December 2016 were retrospectively analyzed. The inclusion criterion was ureteral stents that required intervention above the ureteral orifice to retain and was proved to be encrusted. Impacted stents would be removed by ureteroscope lithotripsy (URL) via 8/9.8F or 4...

With an increased risk of symptomatic events, the complications related to residual fragments are complex and intractable. The management of stone fragments is a challenge to urologists. This review focused on the progress, status, and needs of the newly developed physical therapies to remove fragments and improve the stone-free rate. Physical therapies, including mechanical percussion, diuresis, and inversion therapy, ultrasonic propulsion technology, glue-clot technology, and magnetization technology, will facilitate progress in endoscopic stone fragment retrieval...

Our previous study has shown that lime powder (LP) had an inhibitory effect against calcium oxalate stone formation. However, the precise mechanisms underlying such beneficial effect remained unclear. Our present study thus aimed to address the effect of LP on excretory level and compositions of urinary proteins using a proteomics approach. From a total of 80 calcium oxalate stone formers recruited into our 2-year randomized clinical trial of LP effect, 10 patients with comparable age and clinical parameters were selected for this proteomic study...

Percutaneous nephrolithotomy (PCNL) is a commonly used type of minimally invasive treatment in kidney stone surgeries. Surgical success is assessed according to residual stone amount after surgery. The purpose of this study is to compare the two methods' success and practicality that are applied after the fracture of the stone in the patients who applied PCNL and which enable the removal of the residual stones. Among 102 patients who underwent a single-session of PCNL at our department between June 2015 and November 2016 were evaluated...

Desmosium styracifolium (D. styracifolium), which is considered as a Chinese herbal medicine, has been reported to treat the kidney stone diseases. However, the potential phytochemically active components and the underlying mechanisms associated with its efficacy in targeting urolithiasis remain to be elucidated. This study aims to investigate the anti-urolithiatic effect of total flavonoids of D. styracifolium (TFDS) on calcium oxalate (CaOx) renal stones in Sprague-Dawley rats. Animal models of CaOx urolithiasis were established in male Sprague-Dawley rats by adding 5% w/w hydroxy-L-proline (HLP) in regular rat chow...

The objective of this study was to determine risk factors of hospital admission for treatment of complications after extracorporeal shock wave lithotripsy (SWL). The electronic files and images of all patients who underwent SWL for treatment of renal stones between January 2011 and December 2015 were retrospectively reviewed. All patients underwent SWL with the same electromagnetic lithotripter (Dornier Lithotripot S). The data of those who needed hospital admission for treatment of complications within 30 days after SWL were compared with patients who did not require hospital admission...

Pediatric population has increasing incidence of renal calculus and it is estimated to be around 50/10,000 population. The treatment of choice for large and complex stone in anomalous kidney is percutaneous nephrolithotomy (PCNL). The fate of insignificant residual fragment after PCNL in pediatric patients is not well documented. Here, we are reporting our long-term experience and follow-up of insignificant residual fragment in pediatric patients with anomalous kidney in comparison to normal kidney. Intuitional ethical approval was taken...

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...

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...
