BACKGROUND: Nephrolithiasis is one of the causes which lead to chronic kidney disease (CKD). Matrix metalloproteinases (MMPs) are endopeptidases degrading extracellular matrix which correlate with the pathogenesis of atherosclerosis. The current study was designed to analyze the association of (R279Q, C1562T) polymorphism of MMP-9 with nephrolithiasis patients. METHODS: Genotyping of MMP-9/R279Q and of MMP-9/C1562T polymorphism were carried out by PCR-based restriction digestion method...

BACKGROUND: There is a need for pediatric medical devices that accommodate the unique physiology and anatomy of pediatric patients that is increasingly receiving more attention. However, there is limited literature on the programs within children's hospitals and academia that can support pediatric device development. We describe our experience with pediatric device design utilizing collaborations between a children's hospital and two engineering schools. METHODS: Utilizing the academic year as a timeline, unmet pediatric device needs were identified by surgical faculty and matched with an engineering mentor and a team of students within the Capstone Engineering Design programs at two universities...

BACKGROUND: Zinc is an essential metal involved in many physiological processes. Previous work has identified a set of zinc transporters involved in Drosophila dietary zinc absorption. However, zinc excretion and reabsorption, the other two important processes to maintain zinc homeostasis, are not as well understood. In this work, we screened all the potential zinc transporter Zip (SLC39) and ZnT (SLC30) members for their likely roles in zinc excretion in Malpighian tubules, an insect organ functionally analogous to mammalian kidneys...

Bone demineralization, dehydration and stasis put astronauts at increased risk of forming kidney stones in space. The color-Doppler ultrasound "twinkling artifact," which highlights kidney stones with color, can make stones readily detectable with ultrasound; however, our previous results suggest twinkling is caused by microbubbles on the stone surface which could be affected by the elevated levels of carbon dioxide found on space vehicles. Four pigs were implanted with kidney stones and imaged with ultrasound while the anesthetic carrier gas oscillated between oxygen and air containing 0...

OBJECTIVE: To evaluate the prevalence of asymptomatic microscopic hematuria (AMH) in women presenting with POP, as well as the relationship of POP stage with AMH. MATERIALS AND METHODS: Charts of women evaluated in a Female Pelvic Medicine and Reconstructive Surgery clinic between January 2015 and July 2016 were retrospectively reviewed. The prevalence of AMH (≥3 red blood cells per high-powered field on 1 urinalysis) was compared for women with symptomatic POP and those with urinary incontinence (UI) without symptomatic POP...

BACKGROUND: Using a proteomic approach, we aimed to identify and compare the urinary excretion of proteins involved in lipid transport and metabolism in children with kidney stones and hypercalciuria (CAL), hypocitraturia (CIT), and normal metabolic work-up (NM), and in healthy controls (HCs). Additionally, we aimed to confirm these results using ELISA, and to examine the relationship between the urinary excretion of selected proteins with demographic, dietary, blood, and urinary parameters...

PURPOSE: Resveratrol (RES) is a polyphenol with antioxidant, anti-inflammatory, and many other physiological effects on tissues. In the present study, the effect of resveratrol in hyperoxaluria driven nephrolithiasis/nephrocalcinosis is investigated. METHODS: Wistar-Albino rats of 250-300 g (male, n = 24) were included in the present study. The rats were randomized into three groups: Group 1 consisted of the controls (n = 8), Group 2 of hyperoxaluria (1% ethylene glycol (EG), n = 8), and Group 3 of the treatment (1% EG + 10 mg/kg of RES, n = 8) group...

Retrograde ureteric stone migration is an extremely rare phenomenon with only one previously reported case in the literature. We report on a case of upward spontaneous migration of a ureteric stone in a 39-year-old male military trainer in Saudi Arabia who was diagnosed with upper left ureteric stone based on non-contrast spiral computerized tomography kidney ureter bladder (CT-KUB) scan. The plan was to treat the patient conservatively with alpha blockers and oral hydration. Two weeks after treatment started, repeated CT-KUB scan revealed an upward migration of the stone to the left renal calyx...

BACKGROUND: Urinary stone disease (USD) is increasing in adult and pediatric populations Adult and pediatric studies have demonstrated decreased bone mineral density and increased fracture rates. USD has also been independently linked to increased rates of myocardial infarction and cerebral vascular accidents. Although USD is a multisystem disorder involving the kidneys, bone and vasculature, the molecular mechanisms linking these three organs remain unknown. METHODS: Calcium oxalate nephropathy was induced in C57BL/6J mice with intra-peritoneal (ip) injection of sodium glyoxolate...

INTRODUCTION AND OBJECTIVE: Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for kidney stones regardless of age. Elderly patients (EP)≥65years old, in growing numbers, have more comorbidities than the general population, may alter results of PCNL. The aim of this meta-analysis was to compare efficacy and complications of this procedure between EP and young patients (YP). METHODS: Original studies of prospective and historical cohorts, in English or French, presenting PCNL series published on PubMed until 2015 were identified using the keywords percutaneous nephrolithotomy, elderly patients, kidney stones and staghorn calculi...

PURPOSE: Recent reports support the use of renal ultrasonography (US) as the initial imaging study for the evaluation of patients with suspected renal colic. Urologists, however, often advocate for computed tomography (CT) to better define stone size and location, especially prior to proceeding with endourologic intervention. One concern with using US as the initial imaging study is that CT may be required at a later time, obviating the reduction in costs and radiation gained by using US...

BACKGROUND: There is growing international evidence that nurse-led chronic kidney disease (CKD) clinics provide a comprehensive approach to achieving clinical targets effective in slowing the progression of CKD. Across Queensland, Australia, these clinics have been established in many renal outpatient departments although patient satisfaction with these clinics is unknown. OBJECTIVES: To measure patient satisfaction levels with CKD nurse-led clinics. METHOD: This was a cross-sectional study undertaken at five clinics located in metropolitan, regional and remote hospitals in Queensland...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) has been widely used to treat renal stones. The application of PCNL in obese patients results in the emergence of a number of challenges. This study compared the effect of obesity on the outcomes of PCNL in kidney stone treatment. METHODS: Eligible studies were searched in PubMed, Web of Science, and Cochrane Library databases. Data were analyzed using RevMan statistical software, weighted mean differences, ORs, and 95% CIs were calculated...

Urinary crystals with various sizes are present in healthy individuals and patients with kidney stone; however, the cellular uptake mechanism of calcium oxalate of various sizes has not been elucidated. This study aims to compare the internalization of nano-/micron-sized (50 nm, 100 nm, and 1 μm) calcium oxalate monohydrate (COM) and dihydrate (COD) crystals in African green monkey renal epithelial (Vero) cells. The internalization and adhesion of COM and COD crystals to Vero cells were enhanced with decreasing crystal size...

Retrograde ureteroscopy (URS) has become a common procedure for the management of urinary stones. Although its efficacy and safety are well known, the literature about major complications is still poor. This study highlighted some cases of life-threatening complications after semirigid ureteroscopy (s-URS) or flexible ureteroscopy (f-URS). We enrolled experienced endourologists (more than 75 cases/year in the last 3 years) and we performed a survey asking to review their series and report the cases encumbered by major complications (Clavien-Dindo IIIb-IV grade)...

BACKGROUND: Although the relationship between a history of kidney stones and chronic kidney disease (CKD) has been explored in many studies, it is still far from being well understood. Thus, we conducted a meta-analysis of studies comparing rates of CKD in patients with a history of kidney stones. METHODS: PubMed, EMBASE, and the reference lists of relevant articles were searched to identify observational studies related to the topic. A random-effects model was used to combine the study-specific risk estimates...
