Current urate-lowering therapy (ULT) includes three direct acting drugs (allopurinol, febuxostat, Rasburicase) and at least four 'indirect' drugs with other important targets (canagliflozin, losartan, fenofibrate and sevelamer). Moreover, the alcalinization of urines using bicarbonate can be used to dissolve urate crystals and the clinician may discontinue several drugs are known to increase serum levels of uric acid, such as diuretics, aspirin, cyclosporine, theophylline, mycophenolate and ACE inhibitors. While there is a consensus to start ULT in cases of symptomatic hyperuricemia (gout, urate-nephrolithiasis), the very frequent conditions of asymptomatic hyperuricemia remains a major conundrum...

Uric acid nephrolithiasis appears to increase in prevalence. While a relationship between uric acid stones and low urinary pH has been for long known, additional association with various metabolic conditions and pathophysiological basis has recently been elucidated. Some conditions such as diabetes and metabolic syndrome disease, excessive dietary intake, and increased endogenous uric acid production and/or defect in ammoniagenesis are associated with low urinary pH. In addition, the phenomenon of global warming could result in an increase in areas with greater climate risk for uric acid stone formation...

Byeong Kyu Park, Gwang Ha Kim
A fistula between the renal pelvis and duodenum (pyeloduodenal fistula) is very rare. It can occur spontaneously or after trauma to one of these organs. A spontaneous pyeloduodenal fistula is usually caused by chronic inflammation, including reactions to foreign bodies, nephrolithiasis, benign and malignant neoplasms, as well as pyogenic infections. The main treatment to date has been surgery. We encountered one case of pyeloduodenal fistula found during an evaluation for abdominal discomfort in a 39-year-old female...

The calcium-sensing receptor (CaSR) gene plays an important role in regulating the Ca2+ balance and reducing the risk for calcium stones. In this study, we evaluated the association of CaSR polymorphisms with calcium nephrolithiasis in the population of Yi nationality in Southwestern China. Biochemical variables were evaluated in 624 calcium nephrolithiasis patients and 470 age-matched healthy controls without a history of nephrolithiasis. CaSR polymorphisms rs7652589, rs1501899, rs1801725 (Ala986Ser), rs1042636 (Arg990Gly) and rs1801726 (Gln1011Glu) were investigated between the calcium nephrolithiasis patients and healthy controls, using direct sequencing...

Nephrolithiasis is a rare disease in children. For many years children with kidney stones have been managed like "small adults", but there are significant differences between the pediatric and the adult age in clinical presentation, etiology and treatment. Management of this condition in children has some peculiarities with respect to the adult, as it is often the sign of an underlying metabolic abnormality. Some of these metabolic alterations can lead to serious consequences, such as chronic renal failure, if not adequately diagnosed and treated...

Systemic oxalosis can be either primary or secondary hyperoxaluria. Oxalosis is a phenomenon in which calcium oxalate crystals deposit in various visceral organs leading to bone marrow (BM) failure and recurrent renal stones. We describe two rare cases of BM oxalosis. Hyperoxaluria is strongly associated with nephrolithiasis and nephrocalcinosis. Both the patients presented with recurrent renal stones and a variable degree of BM failure. BM oxalosis should be considered as a possible diagnosis in patients in recurrent nephrolithiasis and cytopenia...

Rare renal diseases (RRD) are an important category of rare disease (RD) as they can do great damage to the patients, families and society. The patient may undergo years even decades of numerous investigations including invasive procedures and yet not have definitive and precise diagnose and therefore, no opportunity for appropriate treatment. The great progress in molecular genetic techniques characterized many Mendelian diseases on molecular level. This gave the possibility for appropriate prevention and treatment interventions, genetic counseling and prenatal diagnosis...

Numerous epidemiological studies have shown that male patients with uric acid nephrolithiasis outnumber female patients. To our knowledge, no research exists evaluating the reasons gender affects the development of uric acid nephrolithiasis. We hereby used a novel application of structural equation modeling to analyze the mediators of the effects of gender on uric acid nephrolithiasis. In 1,098 patients with nephrolithiasis between 2012 and 2016, male gender was found to have a statistically significant positive indirect effect on the development of uric acid nephrolithiasis, which was mediated by lower urine pH (estimate: 0...

Madhumitha Reddy, Karim Kader
Bladder cancer is the sixth leading cancer in the United States. Radical cystectomy is a lifesaving procedure for bladder cancer with or without muscle invasion. Radical cystectomy is performed on 39% of these patients, and 35% will have a life-threatening recurrence. Distant metastases are the most common; local, upper tract, and urethral recurrence can also occur. Surveillance after cystectomy is critical to diagnosing recurrence early. Functional complications after urinary diversion include bowel dysfunction, vitamin B12 deficiency, acidosis, electrolyte abnormalities, osteopenia, nephrolithiasis, urinary tract infections, renal functional decline, and urinary obstruction, which can be reversed when diagnosed early...

OBJECTIVES: To compare the sensitivity of non-contrast CT to endoscopy for detection of renal calculi. Imaging modalities for detection of nephrolithiasis have centered on abdominal x-ray (KUB), ultrasound (US), and non-contrast computed tomography (CT). Sensitivities of 58-62% (KUB), 45% (US), and 95-100% (CT) have been previously reported. However, these results have never been correlated with endoscopic findings. METHODS: Idiopathic calcium oxalate stone formers with symptomatic calculi requiring ureteroscopy (URS) were studied...

Chinese herbal medicine has been practiced for the prevention, treatment, and cure of diseases for thousands of years. Herbal medicine involves the use of natural compounds, which have relatively complex active ingredients with varying degrees of side effects. Some of these herbal medicines are known to cause nephrotoxicity, which can be overlooked by physicians and patients due to the belief that herbal medications are innocuous. Some of the nephrotoxic components from herbs are aristolochic acids and other plant alkaloids...

The Mediterranean Dietary (MedDiet) Pattern has been linked to many beneficial health effects. This review summarizes the main findings of a prospective cohort study, the Seguimiento Universidad de Navarra (SUN) cohort, specifically focused on MedDiet and the risk of major chronic disease. It is an open cohort in which 22,786 Spanish university graduates have participated since 1999 until February 2018. Data on diet, lifestyle and clinical diagnosis are collected at baseline and every two years. After reviewing 21 publications from the SUN cohort on the effects of the MedDiet, we conclude that this cohort has provided good evidence that a high MedDiet adherence is associated with a reduced incidence of all-cause mortality, fatal and non-fatal major cardiovascular disease (CVD), type 2 diabetes, weight gain, metabolic syndrome, depression, cognitive decline, and nephrolithiasis...

INTRODUCTION: Nephrolithiasis is one of the most common diseases in urology. According to the EAU Guidelines, a percutaneous nephrolitholapaxy (PNL) is recommended when treating a kidney stone >2 cm. Nowadays PNL is performed even for smaller stones (<1 cm) using miniaturized instruments. The most challenging part of any PNL is the puncture of the planned site. PNL-novice surgeons need to practice this step in a safe environment with an ideal training model. We developed and evaluated a new, easy to produce, in-vitro model for the training of the freehand puncture of the kidney...
