Large cohort studies on whether any association existed between urological interventions for urolithiasis and the development of CKD are lacking. From claims data of the National Health Insurance (NHI) program of Taiwan, we identified 54,433 patients newly diagnosed with urolithiasis during 1998-2010. For each case, four individuals without urolithiasis were randomly selected and frequency matched by age, sex, and diagnosis year. Both groups were followed up until the end of 2010. Incident CKD events were identified by the International Classification of Diseases, Ninth Revision (ICD-9) code in the NHI registration database...

OBJECTIVE: To study brushite stone formers (BSF) change in renal function and overall risk of progression to chronic kidney disease (CKD) over time. MATERIALS AND METHODS: A retrospective review of all patients with urolithiasis on stone analysis was performed from 1995-2003. Stones were classified as brushite if they had at least 10% brushite composition on analysis. Patients with a minimum of 6 years clinical follow-up were included in the study. BSF were matched 1:3 to idiopathic calcium oxalate stone formers (CaOxSF) over the same time period...

Urolithiasis, a complex multifactorial disease, results from interactions between environmental and genetic factors. Epidemiological studies have shown the association of urolithiasis with a number of lifestyle-related diseases, including cardiovascular diseases, hypertension, chronic kidney disease, diabetes and metabolic syndrome. Elucidation of the mechanisms underlying urinary stone formation will enable development of new preventive treatments. The present article reviews the epidemiology, pathophysiology and potential treatment of urolithiasis...

BACKGROUND AND OBJECTIVES: Epidemiological evidence suggests that patients with urolithiasis are at increased risk for end-stage renal disease (ESRD). It is unclear if urological intervention impacts the progression of chronic kidney disease (CKD). METHODS: We conducted a retrospective observational cohort study of patients in the Marshfield Epidemiologic Study Area database between January 1991 and May 2007, where 1,340 patients diagnosed with urolithiasis were extracted...

Hyperoxaluria is a well-recognised risk factor for urolithiasis and patients with primary hyperoxaluria (PH) gradually build up calcium oxalate deposits leading to chronic kidney disease. Efforts to improve treatment for PH have focused on reducing urine oxalate excretion and thus decreasing lithogenesis. To determine the efficacy of treatments designed to alter a biochemical parameter it is necessary to know the biological and analytical variation of that parameter. In this study, we estimated the intra-individual biological variation of urine oxalate excretion in patients with PH, and from this determined what would constitute a significant change in the form of a reference change value (RCV)...

Hoon Young Choi, Hyeong Cheon Park, Sung Kyu Ha
Impact of water intake on the courses of chronic kidney and urinary tract diseases, such as urolithiasis, urinary tract infections, chronic kidney diseases (CKD), autosomal dominant polycystic kidney diseases and bladder cancer, has recently been studied. It still remains controversial whether increased water intake slows the progression of CKD or not. However, high water intake suppresses plasma levels of arginine vasopressin (AVP), which is expected to be beneficial for the preservation of the kidney function...

In this study we sought to determine if among individuals with urolithiasis, extracorporeal shock wave lithotripsy (SWL) and ureteroscopy are associated with a higher risk of incident arterial hypertension (HTN) and/or chronic kidney disease (CKD). This was measured in a population-based retrospective study of 11,570 participants with incident urolithiasis and 127,464 without urolithiasis in The Health Improvement Network. Patients with pre-existing HTN and CKD were excluded. The study included 1319 and 919 urolithiasis patients with at least one SWL or URS procedure, respectively...

Nowadays, increasing of renal pathology, especially of its chronic forms characterized by long clinical duration and frequent exacerbations is observed in pregnant women. The study was carried out to analyze prevalence and structure of renal pathology in pregnant women with further development of social economic basics of its prevention. The epidemiological analysis established that during 2009-2011 in Baku prevalence of renal pathology in pregnant women amounted to 11%. The analysis of structure and dynamics of renal pathology in pregnant women during the same period revealed that leading positions are taken by chronic pyelonephritis (27...

Primary hyperoxaluria type 1 is a rare autosomal-recessive disease caused by the deficient activity of the liver specific enzyme alanine-glyoxylate aminotransferase. Increased endogenous oxalate production induces severe hyperoxaluria, recurrent urolithiasis, progressive nephrocalcinosis and renal failure. Here we report a 6 month old boy who presented with vomiting and decreased urine volume. He was diagnosed with chronic kidney failure at 4 months of age and peritoneal dialysis was introduced at a local hospital...

Severe worsening lactic acidosis in an elderly patient following an episode of atrial fibrillation, who is not haemodynamically compromised, usually indicates an intra-abdominal vascular catastrophe. We describe a unique case of severe peri-renal sepsis in a patient with long-standing dialysis-dependent chronic kidney disease unrelated to urolithiasis that masqueraded as an acute abdominal condition requiring emergency laparotomy and nephrectomy.

While associations exist between water, hydration, and disease risk, research quantifying the dose-response effect of water on health is limited. Thus, the water intake necessary to maintain optimal hydration from a physiological and health standpoint remains unclear. The aim of this analysis was to derive a 24 h urine osmolality (U(Osm)) threshold that would provide an index of "optimal hydration," sufficient to compensate water losses and also be biologically significant relative to the risk of disease...

Ureteric strictures can be caused by traumatic pelvic surgery, urolithiasis and instrumentation. There are various treatment options for ureteric stricture, including laparoscopic ureteric reimplantation. A 56-year-old female with a history of chronic left pelviureteric junction obstruction presented with urosepsis secondary to right-sided urolithiasis. The patient had a left nephrectomy and developed right-sided ureteric stricture following repeated ureteroscopy to manage her stone disease. The treatment with ureteric stenting was unsuccessful...

Atazanavir is commonly used as one of the key drugs in combination antiretroviral therapy for human immunodeficiency virus (HIV). However, atazanavir has the potential to yield its crystalline precipitation in urine and renal interstitial tissues, leading to crystalluria, urolithiasis, acute kidney injury (AKI) or chronic kidney disease (CKD). In epidemiological studies, atazanavir/ritonavir alone or in combination with tenofovir has been associated with increased risk of progression to CKD. However, renal biopsies were not provided in these studies...

Fasting during Ramadan is prohibited when an individual's health is endangered. Little work has been published in this direction in patients with chronic kidney disease (CKD). We aimed to evaluate the impact of fasting during Ramadan on the renal function of patients with CKD, adjusting for the initial degree of renal impairment. We prospectively studied 60 patients with CKD (35 females; mean age 45.6 ± 15.8 years). All study patients were older than 15 years, being followed-up at the nephrology clinic for more than six months, having a stable CKD during the preceding six months and who had fasted during Ramadan the previous year...
