... was higher in patients with uric acid (17/37, 45.9%) and struvite stones (11/27, 40.7%) than in calcium stone formers (35/188, 18.6%) (χ 2 16.31, p < 0.001). The prevalence of hypercalciuria was higher in the calcium stone group than in uric acid or struvite stone patients (36.4 vs. 9.7 vs. 13.7%; χ 2...

... The absorptive or renal origin of hypercalciuria can be discriminated using an acute oral calcium load test (ACLT). Of 86 patients with calcium oxalate kidney stones, 28 (23%) were found to be hypercalciuric (HCa) and 58 (67%) normocalciuric (NCa) on their customary free diet, containing 542 ± 29...

... Hypercalciuria in the absence of urolithiasis has been considered to be a cause of asymptomatic hematuria. No mechanism for this association has been demonstrated. In an effort to establish the specificity of this association, we induced hypercalciuria in 10 healthy subjects by oral administration...

...Antonio Torralbo; Emeterio Pina; José Portolés; Ana Sánchez-Fructuoso; Alberto Barrientos We report a case of congenital magnesium-losing kidney with associated hypercalciuria and ocular derangements consisting of myopia, bilateral macular colobomata and bilateral papillary dysversion...

... bilateral or unilateral nephrocalcinosis, as demonstrated by abdominal computed tomography scans. Renal histology revealed calcinosis of renal tubules in 2 patients. Computed tomography is a reliable method for the detection of nephrocalcinosis in this disorder. Hypercalciuria was also seen in 6 patients...

...Bernd Hoppe; Thomas Neuhaus; Andrea Superti-Furga; Ishilde Forster; Ernst Leumann Hypercalciuria and nephrocalcinosis are not uncommon in patients with Wilson’s disease but have only once been reported as the presenting sign. We diagnosed Wilson’s disease in a 17-year-old male patient 6 years after...

...Martin Tieder; Raphael Arie; Itai Bab; Joseph Maor; Uri A. Liberman Hereditary hypophosphatemic rickets with hypercalciuria (HHRH) is a new autosomal form of hypophosphatemic rickets, recently described. This disease is characterized, and differs from other forms of hereditary hypophosphatemic...

Wang Idiopathic hypercalciuria, though a common cause of nephrolithiasis, has not been recognized to cause hypocalcemia and severe bone disease. We describe an adolescent with idiopathic...

... remained unchanged. All subjects had significant increases in nephrogenous cyclic AMP, suggesting that parathyroid activity is elevated in subjects with furosemide-induced hypercalciuria. With furosemide, fecal calcium was significantly decreased, and resultantly, there was no significant change...

...André Ulmann; Samia Hadj; Bernard Lacour; Agnès Bourdeau; Cyrille Bader We report a 29-year-old man with a mild decrease in glomerular filtration, nephrocalcinosis, hypercalciuria and a renal magnesium leak. He had other features of ‘congenital magnesium-losing kidney’, such as arthritis...

...D.F. Geary; M.J. Dillon; K. Gammon; T.M. Barratt 3 patients are described in whom proteinuria was detected on routine urine analysis and subsequently shown to be predominantly tubular in origin. Renal biopsies showed only minor changes. Hypercalciuria was also noted in 1 of the 3 patients...

... calcium and a significant increase in urinary cyclic AMP from the control to the furosemide periods: this suggests that furosemide-induced hypercalciuria produced elevated parathyroid activity. After treatment with furosemide, the response of urinary cyclic AMP and phosphate to PTE was blunted. During...

... hyperoxaluria as urinary oxalate excretion greater than 2 SD above normal, 50% of stone-forming people were found to be hyperoxaluric. When stone formers were classified in normo- and hyperoxaluric, the prevalence of hypercalciuria, hyperuricuria, family history of stone disease and recurrencies in stone...

...Ibrahim S. Salti; Kamal Hemady An unusual case of rickets associated with hypercalciuria is described. In addition to proteinuria, the patient had phosphaturia, aminoaciduria, renal glucosuria and impaired renal concentration but no renal tubular acidosis. Studies did not support the diagnosis...

...W.G. Robertson; M. Peacock Hypercalciuria is common in patients who form calcium oxalate urinary stones and is considered by many to be the cause ofthe disorder. This review shows that there is little relationship between either the rate of stone-formation or calcium oxalate crystalluria...

In the light of these findings, the diagnosis of incomplete renal Fanconi syndrome was made. In conclusion, on the basis of the present findings...

... with idiopathic hypercalciuria (HC). However, the respective role played by Na and K excretion in the rise of the UNa/K in growing individuals is not well clarified. Methods: The urinary excretion of Na and K was evaluated in fasting morning and 24-hour urine samples of 37 consecutive children with HC and of 21...
