Kidney stone disease represents a rare cause of chronic kidney disease (2–3%) but has severe clinical consequences. Type 1 renal tubular acidosis is a strong lithogenic condition mainly related to primary Sjögren syndrome. This study aimed to illustrate an unusual presentation of Sjögren syndrome to improve the knowledge about rare kidney stone diseases, and to … Leggi tutto
Hypercalciuria is an important, identifiable, and reversible risk factor in stone formation. The foremost and most fundamental step in dissecting the genetics of hypercalciuria is understanding its pathophysiology. Hypercalciuria is a complex trait. This article outlines the various factors that compromise the attempt to dissect the genetics of hypercalciuria, summarizes the clinical and experimental monogenic … Leggi tutto
Correction to: Kidney International (2011) 80:1278–1291; doi:10.1038/ki.2011.336 In the above-cited article, Table 2 was published with incorrect alignment of age ranges and erroneous unit changes concerning the cystine and urate excretion levels. The urate gram units needed to be multiplied by 10. In Table 1, the diagnosis related to NPT2a mutations should read ‘Urolithiasis, osteoporosis, … Leggi tutto
Kidney stone disease (nephrolithiasis) is a common problem that can be associated with alterations in urinary solute composition including hypercalciuria. Studies suggest that the prevalence of monogenic kidney stone disorders, including renal tubular acidosis with deafness, Bartter syndrome, primary hyperoxaluria and cystinuria, in patients attending kidney stone clinics is ∼15%. However, for the majority of … Leggi tutto
Kidney stone disease comprising nephrolithiasis and nephrocalcinosis is a clinical syndrome of increasing prevalence with remarkable heterogeneity. Stone composition, age of manifestation, rate of recurrence, and impairment of kidney function varies with underlying etiologies. While calcium-based kidney stones account for the vast majority their etiology is still poorly understood. Recent studies underline the notion that … Leggi tutto

Distal renal tubular acidosis (dRTA) is characterized by an impaired ability of the distal tubule to excrete acid, leading to metabolic acidosis. Associated complications include bone disease, growth failure, urolithiasis and hypokalaemia. Due to its rarity, there is limited evidence to guide diagnosis and management; however, available data strongly suggest that metabolic control of the … Leggi tutto
Context: An optimum metabolic evaluation strategy for urinary stone patients has not been clearly defined. Objective: To evaluate the optimum strategy for metabolic stone evaluation and management to prevent recurrent urinary stones. Evidence acquisition: Several databases were searched to identify studies on the metabolic evaluation and prevention of stone recurrence in urolithiasis patients. Special interest … Leggi tutto
The pathophysiology of renal tubular acidosis (RTA) seems well worked out. Distal or type 1 renal tubular acidosis (dRTA)leads to positive proton balance,which results in decreased bone mineral density (BMD) and a urinary phenotype most consistent with calcium phosphate stone formation: hypocitraturia, hypercalciuria, and a high urine pH. Nephrocalcinosis and CKD are also seen. Proximal … Leggi tutto
