... (Group 2), NCACT was also divided into 2 groups as PCal presence (PCal+) and lack (PCal–) serum UA, calcium, phosphorus, sodium, prostate-specific antigen levels and urinary analysis results of the patients were evaluated and compared. Results: PCal were detected in 38 of 169 patients (22%). PCal...

...Brittany Fitzpatrick; Catherine Schuler; Robert E. Leggett; Robert M. Levin Purpose: Superoxide dismutase (SOD) and catalase are two important antioxidant mechanisms that work together to reduce free radical damage. Intracellular free calcium in smooth muscle can change rapidly and many enzymes can...

...K. Jarrar; R.A. Amasheh; V. Graef; W. Weidner In order to clarify the role of 1, 25-dihydroxyvitamin-D [1, 25-(OH) 2 -D] in calcium stone formation, correlations between l,25-(OH) 2 -D serum levels and levels of calcium, phosphate and uric acid (UA) in serum or urine and between the l,25-(OH) 2 -D...

...Palle Jörn Osther; Henning Mathiasen; Annebirthe Bo Hansen; Hans Melchior Nissen Urinary acidification ability, acid-base status and urinary excretion of calcium and citrate were evaluated in 10 women with bilateral medullary sponge kidney (MSK) and in 10 healthy women. Patients with MSK had higher...

...William G. Robertson Urinary stone disease is a multifactorial disorder arising essentially from an abnormal combination of a number of urinary risk factors. In the case of calcium urolithiasis the main risk factors are a low urine volume, a high urinary pH, increased excretions of calcium, oxalate...

...Alan Rose; S. Sulaiman Different proportions of mixtures of whole urine and its ultrafiltrate were evaporated to 1,250 mosm/kg to study crystal formation of calcium oxalate at pH 5.3 and calcium phosphate at pH 6.8. At both pH values there was a direct linear relationship between proportion...

...P.C. Hallson; G.A. Rose; S. Sulaiman Crystal formation in whole urine was studied by the technique of rapid evaporation to 1,250 mosmol/l with and without raising citrate concentration by 40–50%. The added citrate reduced calcium oxalate crystal formation at pH 5.3 by about 25 % and reduced calcium...

... hyperparathyroidism (HPT) for periods between 5 and 24 weeks. In all the patients, serum calcium was normalized during treatment, presumably due to a reduction of bone resorption since fasting urinary calcium and urinary hydroxyproline excretion were lowered as well. This pilot study indicates that certain...

...Kenjiro Kohri; Kiyonori Kataoka; Masanori Iguchi; Sunao Yachiku; Takashi Kurita; Takao Sonoda Parathyroid hormone is concerned with urolithiasis, and regulated by serum ionized calcium concentration. We thought that parathyroid hormone might also be regulated by a hormone. 1 mg of ACTH injection...

...V. Revúsová; J. Gratzlová; V. Zvara; J. Krídl; B. Suchánek; J. Breza Several serum and urinary constitutents were evaluated in 13 calcium oxalate kidney stone formers in whom according to urinary vitamin B6 excretion sufficient vitamin B6 intake before the study was suggested. The influence of 28...

... calcium stone compositions. We investigate the efficacy of HU measurement on NCCT to determine if it can differentiate the various calcium stone subtypes. Patients and Methods: Of the 684 patients who had undergone ureteroscopy at our institution from 1/2003 to 10/2007, 100 were identified...

...J.M. Baumann; B. Affolter; U. Caprez; C. Clivaz; U. von Arx Objectives: In urine, aggregation (AGN) of crystal occurs although they are coated by negatively charged urinary macromolecules (UM) and isolated at a distance from each other, where attraction forces become extremely weak. Calcium (Ca...

... hypercalciuria after ESWL. Material and Methods: 30 calcium oxalate stoneformers (23 men, 7 women), mean age 53.3 (range 30–71) years, were evaluated prospectively. Plasma calcium and creatinine concentrations and 8-hour overnight urine were measured before ESWL and on the 1st and 2nd days after ESWL...

... with inguinal hernia (n = 7). The calcium content of the sacs and peritoneal samples (n = 6) was determined through atomic absorption spectrophotometry. Calcium contents were compared according to their sources using the Mann-Whitney U test and p values of <0.05 were considered significant. Results: While...

...) and from girls with inguinal hernia (n = 8) were obtained. The calcium contents of these samples and of samples from internal oblique muscle (n = 6) were determined by atomic absorption spectrophotometry. While the Ca 2+ contents of CM from boys with undescended testis and from girls with inguinal hernia...

... is increased by Tamm-Horsfall protein and that an increased uric acid content in the urine might cause a decrease in Tamm-Horsfall protein. In 20 patients with uric calculi the excretion of Tamm-Horsfall protein, uric acid, calcium, and citrate was measured. 65% of the patients had pure uric acid stones (group...
