BACKGROUND: Calcium nephrolithiasis is associated with an increased risk of osteoporosis and fracture. Hypercalciuria has been assumed to be pathogenic for bone loss in kidney stone formers (KSF), although this association was shown in small cross-sectional studies. We explored the association of urine calcium (UCaV) with bone mineral density (BMD) in KSF. METHODS: We retrospectively studied BMD in KSF. Excluded were subjects with hypercalcemia, chronic bowel disease, primary hyperparathyroidism, distal renal tubular acidosis or endogenous creatinine clearance <40 ml/min...

A horseshoe kidney (HSK) is the most common congenital renal fusion anomaly. HSKs are more likely than normal kidneys to have associated problems of stones, ureteropelvic junction obstruction, stasis and infection. However, they do not have an increased incidence of renal cell carcinoma when compared to normal kidneys. Due to its rarity, accurate diagnosis may be difficult. Of similar significance is the fact that problems may arise during surgery on these kidneys due to altered anatomy and aberrant blood supply...

BACKGROUND: Adenine phosphoribosyltransferase deficiency is an inborn error of metabolism that can cause kidney disease from crystalline nephropathy or kidney stones. METHODS: We present three cases from a single centre with varied presentations to illustrate how increasing awareness led to better patient identification. We then undertook a cross-sectional survey of all the patients identified from the Purine Research Laboratory in the UK since 1974. RESULTS: Our index case presented with recurrent nephrolithiasis and was diagnosed on stone analysis, the second case presented with acute kidney injury and the third case was identified from a biopsy undertaken for acute on chronic kidney injury...

Cystinuria and polycystic kidney disease are 2 genetic disorders that affect the genitourinary tract but rarely together. This case report presents 2 pediatric patients diagnosed with polycystic kidney disease and cystinuria requiring surgical treatment. Both subjects presented acutely with stone disease. Imaging studies and stone analysis established the diagnoses. Although coexistence of these 2 conditions is rare, cystinuria should be considered in the differential diagnosis when evaluating patients with cystic disease who develop renal calculi...

Obesity is a risk factor for a plethora of severe morbidities and premature death. Most supporting evidence comes from observational studies that are prone to chance, bias and confounding. Even data on the protective effects of weight loss from randomized controlled trials will be susceptible to confounding and bias if treatment assignment cannot be masked, which is usually the case with lifestyle and surgical interventions. Thus, whilst obesity is widely considered the major modifiable risk factor for many chronic diseases, its causes and consequences are often difficult to determine...

Renal stone disease is a frequent condition, causing a huge burden on health care systems globally. Calcium-based calculi account for around 75% of renal stone disease and the incidence of these calculi is increasing, suggesting environmental and dietary factors are acting upon a preexisting genetic background. The familial nature and significant heritability of stone disease is known, and recent genetic studies have successfully identified genes that may be involved in renal stone formation. The detection of monogenic causes of renal stone disease has been made more feasible by the use of high-throughput sequencing technologies and has also facilitated the discovery of novel monogenic causes of stone disease...

Recent large 3 cohorts have shown that caffeinated beverage consumption was associated with lower risk of kidney stone disease. However, its protective mechanisms remained unknown and had not been previously investigated. We thus evaluated protective effects of caffeine (1 μM-10 mM) on calcium oxalate monohydrate (COM) kidney stone formation, using crystallization, crystal growth, cell-crystal adhesion, Western blotting, and immunofluorescence assays. The results showed that caffeine reduced crystal number but, on the other hand, increased crystal size, resulting in unchanged crystal mass, consistent with crystal growth that was not affected by caffeine...

Haemophilus species are known to colonize the upper respiratory tract and can cause infections. However Haemophilus influenzae has been rarely described as a cause of genitourinary tract infection. We report a 44-year-old nonimmunocompromised Japanese man with bacteremic pyelonephritis caused by a nontypable H. influenzae associated with a left ureteral calculus. The organism was isolated from both blood and urine cultures. Treatment consisted of 14 days of intravenous ceftriaxone and oral amoxicillin one after than other and insertion of a left ureteral stent...

Medullary sponge kidney (MSK) disease, a rare kidney malformation featuring recurrent renal stones and nephrocalcinosis, continues to be diagnosed using expensive and time-consuming clinical/instrumental tests (mainly urography). Currently, no molecular diagnostic biomarkers are available. To identify such we employed a proteomic-based research strategy utilizing urine from 22 patients with MSK and 22 patients affected by idiopathic calcium nephrolithiasis (ICN) as controls. Notably, two patients with ICN presented cysts...

The intestine exerts a considerable influence over urinary oxalate in two ways, through the absorption of dietary oxalate and by serving as an adaptive extra-renal pathway for elimination of this waste metabolite. Knowledge of the mechanisms responsible for oxalate absorption and secretion by the intestine therefore have significant implications for understanding the etiology of hyperoxaluria, as well as offering potential targets for future treatment strategies for calcium oxalate kidney stone disease. In this review, we present the recent developments and advances in this area over the past 10 years, and put to the test some of the new ideas that have emerged during this time, using human and mouse models...

Animal models are useful in the study of many human diseases. Our current understanding of the biological, physiological, and biochemical aspects of hyperoxaluria and calcium oxalate urolithiasis has been greatly informed by studies using animals. Recently, limitations in the extrapolation to humans of research results derived from laboratory rodents have been identified. The use in biomedical research of a variety of organisms, including large animals, is increasingly encouraged. The purpose of this article is to review the use of pigs in biomedical and stone research, to provide a rationale for using pigs in metabolic stone research, and to describe our 8-year experience in developing a porcine platform for studying hyperoxaluria and calcium oxalate urolithiasis...

This concise review summarizes our current understanding and the recent developments in genetics and related renal tubular disorders that have been linked with, or have been shown to be causal in, renal stone disease. The aim is to provide a readily accessible quick and easy update for urologists, nephrologists and endocrine or metabolic physicians whose practice involves the diagnosis and management of nephrolithiasis. An important message is to always consider a seemingly rare, and usually genetic, cause of kidney stones, since some of these are emerging as more common than originally thought, especially in adult clinical practice in which a family history of stones is a common finding...
