Upper urinary tract calculi with infection is a quite difficult acute urologic emergency. And what is more, upper urinary tract obstruction after radical cystectomy following urinary diversion may be fatal in the vulnerable patients with this kind of situation. Postoperative anatomy and other factors affect the upper urinary tract calculi, and urinary tract infection greatly increased the risk. But it is particularly difficult to handle with patients with poor general condition and septic shock treatment, so how to optimize the selection program is worth further studying...

BACKGROUND: Cystinuria is an inherited disease that results in the formation of cystine stones in the kidney, which can have serious health complications. Two genes (SLC7A9 and SLC3A1) that form an amino acid transporter are known to be responsible for the disease. Variants that cause the disease disrupt amino acid transport across the cell membrane, leading to the build-up of relatively insoluble cystine, resulting in formation of stones. Assessing the effects of each mutation is critical in order to provide tailored treatment options for patients...

The aim of this study was to compare the effect of dietary supplementation with low dose of porous and nano zinc oxide (ZnO) on weaning piglets, and to evaluate the possibility of using them as an alternative to high dose of regular ZnO. Piglets were randomly allocated into four treatment groups fed with four diets: (1) basal diet (NC), (2) NC+ 3000 mg/kg ZnO (PC), (3) NC + 500 mg/kg porous ZnO (HiZ) and (4) NC + 500 mg/kg nano ZnO (ZNP). The result showed that piglets in HiZ group had less diarrhea than ZNP group (P < 0...

AIM: URS is a very commonly used procedure for treatment of ureter stones. Increased hydrostatic pressure in the collecting system linked to fluids used during the procedure may cause harmful effects on the kidney. The aim of this study is to determine whether the URS procedure has a negative effect on the kidney by investigating NGAL, KIM-1, FABP and Cys C levels in urine. MATERIAL AND METHODS: This study included 30 patients undergoing ureterorenoscopy (URS) for ureter stones...

Hypercalciuria is a main risk factor for kidney stone  formation. TRPV5 is the gatekeeper protein for mediating calcium transport and reabsorption in the kidney. In the present study, we tested the effect of TRPV5 activation with small activating RNA (saRNA), which could induce gene expression by targeting the promoter of the gene, on ethylene glycol (EG)-induced calcium oxalate (CaOx) crystals formation in rat kidney. Five pairs of RNA activation sequences targeting the promoter of rat TRPV5 were designed and synthesized...

Renal epithelial cell injury causes crystal retention and leads to renal stone formation. However, the effects of crystal shape on cell injury and stone risk remain unclear. This study compared the cytotoxicity degrees of calcium oxalate dihydrate (COD) crystals having different shapes toward human kidney proximal tubular epithelial (HK-2) cells to reveal the effect of crystal shape on cell injury and to elucidate the pathological mechanism of calcium oxalate kidney stones. The effects of exposure to cross-shaped (COD-CS), flower-like (COD-FL), bipyramid (COD-BD), and elongated-bipyramid (COD-EBD) COD crystals on HK-2 cells were investigated by examining the cell viability, cell membrane integrity, cell morphology change, intracellular reactive oxygen species, mitochondrial membrane potential (Δψm), and apoptotic and/or necrotic rate...

BACKGROUND: As per the recent statistical reports of World Health Organisation (WHO), 13% of total global population is obese. Orlistat remains to be the only drug approved for the long term treatment of obesity. Recent findings highlighted severe adverse effects of orlistat that included hepatotoxicity, gall stones, kidney stones and acute pancreatitis. Therefore, search for new drug is required. The investigations based on endophytic natural products would prove pivotal in the global fight against this health issue...

BACKGROUND/OBJECTIVE: The incidence of pyogenic liver abscess in Taiwan appears to be much higher than that in western countries. However, little is known about the incidence of pyogenic liver abscess among patients with predialysis chronic kidney disease. The objective of this study was to assess the association between predialysis chronic kidney disease and the risk of pyogenic liver abscess in Taiwan.

INTRODUCTION: Percutaneous Nephrolithotomy (PCNL) is the treatment modality used for the extraction of large renal stones, or multiple calculi or stones resistant to shock wave lithotripsy. The General Anaesthesia (GA) is the standard modality for PCNL. However, few studies conclude that Spinal Anaesthesia (SA) can be an alternative method of anaesthesia with similar incidence of complications. AIM: In our study we evaluated the feasibility of spinal anaesthesia in terms of intraoperative and postoperative results in patients undergoing PCNL...

REVIEW
Martino Marangella
Citrate is a tricarboxylic acid and an intermediate metabolite of Krebs cycle. It contributes to oxidative metabolism of both kidney and liver. Alkaline sodium or potassium salts have the potential to increase alkaline reserve. In the kidney citrate is completely filtered at the glomerulus, undergoing to 10-40% tubular resorption. Renal insufficiency, even early, metabolic acidosis, potassium depletion induce hypocitraturia. Its importance in nephrolithiasis stems from its ability to form soluble complexes with calcium and to interfere with crystal formation, thus exerting a dual inhibition, thermodynamic and kinetic...

Copaifera langsdorffii Desf. (Fabaceae, Caesalpinioideae), popularly known as "copaiba" or "pau d'óleo", is a species of tree that is found throughout Brazil. The leaves of this tree are used in folk medicine to treat kidney stones. Galloylquinic acid derivatives and flavonoids are the main secondary metabolites found in C. langsdorffii leaves and are likely to be responsible for the effectiveness of this treatment. As an attempt to produce a phytotherapic, we have developed a reliable HPLC-UV method for the quality control of C...

Patients at high risk of thrombotic events after percutaneous coronary intervention (PCI) may potentially benefit from intensified antiplatelet therapy. However, more potent antiplatelet therapy would be expected to only overcome risk that is mediated by high platelet reactivity (PR). We used mediation analysis to determine the contribution of residual PR to the 2-year risk of major adverse cardiac events (MACE; the composite of cardiac death, myocardial infarction, or stent thrombosis) associated with clinical risk factors after PCI with drug-eluting stents (DES) in 8,374 patients from the prospective, multicenter Assessment of Dual AntiPlatelet Therapy with Drug-Eluting Stents (ADAPT-DES) registry...

Here, we reported our clinical application of ureterorenoscope (URS) and flexible URS lithotripsy in stone removal on 10 cases of excised living donor kidney graft. After the extraction of donor kidney by retroperitoneal laparoscopy, the donor graft was perfused with 4 °C HCA solution. Calculus between 2-4 mm were removed intact with lithotomy forceps under direct vision of URS. Larger calculi of >4 mm were fractured with flexible URS combining holmium laser lithotripsy. Fragments of the calculus were extracted with basket extractor and lithotomy forceps...
