Medical treatment of cystinuria: A twin study of genetic and dietary influences on nephrolithiasis: Hypocitraturia and hyperoxaluria after Roux-en-Y gastric bypass surgery. Do prior AKI episodes nepbrolithiasis adverse impact on the kidney function?

Clinical Review: Kidney Stones Pathogenesis, Diagnosis, and Management

nephrolithoasis The incidence of nephrolithiasis is highest in Caucasian males 2where the incidence of kidney stones rises after age 20, peaks between 40 and 60 yr of age at approximately 3 per per yearand then declines 8. Although hypercalciuric nephrolithiasis is typically a polygenetic complex trait, in rare instances it may be a monogenetic disorder.

Future phenotype-genotype studies are needed to identify the associated gene defect.

Fortunately, melamine—induced renal damage appeared to be reversible, and affected children have been reported to have a satisfactory short and long-term renal prognosis [ 33 ]. Although urinary cystine solubility is pH dependent, alkali treatment alone has limited effectiveness in the management of cystine stone formers.

Clinical and molecular analysis of patients with renal hypouricemia in Japan—influence of URAT1 gene on urinary urate excretion. Cr and fasting urinary phosphorus are obtained to establish the diagnosis of renal leak calcium, excessive calcium mobilization from bone, and renal phosphorus leak.


Beverage use and risk for kidney stones in women. Shock wave lithotripsy and diabetes mellitus: Therefore, imaging studies play a crucial diagnostic role.

J Am Soc Nephrol Is selective therapy of recurrent nephrolithiasis possible? Open in a separate window. A single hour urine collection is inadequate for the medical evaluation of nephrolithiasis. Molecular mechanisms of crystal-related kidney inflammation and injury. However, due to the complex nature of idiopathic hypercalciuria, many putative candidate genes have been identified that participate in this polygenic illness. Hypocitraturia commonly occurs with metabolic acidosis or acid loading mediated through up-regulation of proximal renal tubular reabsorption of citrate Low urinary pH appeared to be an important cofactor that favored melamine crystal deposition and AKI [ 32 ].

Ammonium is a major buffer that neutralizes hydrogen protons secreted by the kidney. Effect of low-carbohydrate high-protein diets on acid-base balance, stone-forming propensity, and calcium metabolism. This article has been cited by other articles in PMC. Int J Antimicrob Agents Excessive crystal agglomeration with low citrate excretion in recurrent stone-formers. Intratubular crystallization events can lead to an obstructive uropathy on a microscopic level, for example in uric acid nephropathy.

Random h urine profile and h urine profile after 1 wk of dietary restrictions. In one study conducted in a Sardinian cohort, most subjects exhibited low urinary pH with high urinary titratable acidity, with only one third showing elevated urinary UA excretion In enteric hyperoxaluria, the underlying mechanisms are purported to be increased permeability to oxalate with unabsorbed bile acid and fatty acids interacting with divalent cations in the lumen of the intestine, thereby raising intestinal luminal oxalate content and resulting in excessive urinary oxalate excretion Recent studies report that a discrepancy between serum cystatin C and creatinine levels can also be a clue that suggests a post-renal cause [ 910 ].


NADPH oxidase as a therapeutic target for oxalate induced injury in kidneys. In females, the incidence rate is higher in the late 20s, decreases by age 50, mephrolithiasis remains relatively constant thereafter 28. Correction of hypocitraturia and prevention of stone formation by combined thiazide and potassium citrate therapy in thiazide-unresponsive hypercalciuric nephrolithiasis.

Kidney Stones 2012: Pathogenesis, Diagnosis, and Management

Its excretion corresponds with urinary sulfate acid load. Unlike CaOx, in CaP stone formers there is apatite crystal deposition in the inner medullary collecting duct, producing plugs associated with interstitial scarring Gastrointestinal calcium absorption in nephrolithiasis.

One suggested mechanism for the formation of calcium stones is increased urinary supersaturation of stone-forming salts, which leads to homogeneous nucleation in the lumen of the nephroithiasis, followed by crystal growth and consequent obstruction in the distal nephron 5.

Am J Physiol Renal Physiol Clinical features and management of cystinuria.

A higher excretion may increase the risk of CaP stone formation. Evidence Acquisition and Synthesis:
