Urine specimens were collected from 26 normal subjects, 10 patients with proven primary hyperparathyroidism, and eight patients with hypercalcaemia due to other causes. After overnight urine concentration, an oral water load was given to induce a diuresis and provide urine specimens with a relatively wide range of creatinine concentration for each subject. In normal subjects the urinary calcium...

Background Association between casual and 24-h urinary sodium-to-potassium (Na/K) ratio is well recognized, although it has not been validated in diverse demographic groups. Our aim was to assess utility across and within populations of casual urine to estimate 24-h urinary Na/K ratio using data from the INTERSALT Study. Methods The INTERSALT Study collected cross-sectional standardized data ...

Blood pressure was measured in the north and in the south of the People's Republic of China in 1002 men and 1006 women. The 24-hour urinary excretion of sodium, potassium, calcium, magnesium, and creatinine was measured, and the relationship between urinary cations and blood pressure was studied. Blood pressure and 24-hour sodium excretion were higher in northern China than in southern China. W...

The urinary calcium/creatinine ratio (UCa/Cr) in spot urine samples has been used extensively for screening and diagnosis of hypercalciuria (HC). The aim of this study was to determine the normal values for UCa/Cr, urinary sodium/creatinine (UNa/Cr), urinary potassium/creatinine (UK/Cr) and urinary sodium/potassium (UNa/K) ratios in healthy Turkish children aged 0-5 years. A total of 425 childr...

background:the first step in diagnosis of diabetic nephropathy is measurement ofalbumin in a spot urine sample. the aim of this study was assessment of the accuracy of urinary albumin to creatinine ratio (uacr) in random urine specimens (rus) for microalbuminuria and macroalbuminuria screening in iranian diabetic patients. methods:a total of 200 diabetic patients participated to our study. 24 h...

Phyllanthus niruri (P.niruri) or stone breaker is a plant commonly used to reduce stone risk, however, clinical studies on this issue are lacking. OBJECTIVE To prospectively evaluate the effect of P. niruri on the urinary metabolic parameters of patients with urinary lithiasis. MATERIALS AND METHODS We studied 56 patients with kidney stones <10mm. Clinical, metabolic, and ultrasonography as...

BACKGROUND Data from studies assessing the intake of potassium, and the concomitant sodium-to-potassium ratio are limited. The aim of this study was to evaluate potassium and sodium-to-potassium ratio intake in 8-10 year-old children. METHODS A cross-sectional survey was carried out from January to June 2014 and data from 163 children (81 boys) were included. Potassium intake was estimated by...

background urinary tract infection (uti) is common in children. uti with or without vesico-ureteral reflux (vur) may result in renal scarring. severe renal scarring impairs renal function and may result in hypertension, renal insufficiency, and end stage renal disease requiring dialyses or transplantation. beta 2 micro-globulin (ß2mg) is a low molecular weight protein freely filtered by the glo...

BACKGROUND High protein diet has been known to cause metabolic acidosis, which is manifested by increased urinary excretion of nitrogen and calcium. Bodybuilders habitually consumed excessive dietary protein over the amounts recommended for them to promote muscle mass accretion. This study investigated the metabolic response to high protein consumption in the elite bodybuilders. METHODS Eight...

High urinary sodium-to-potassium ratio is considered a strong risk factor for hypertension. This study aimed to evaluate excretion of sodium and potassium, we analyzed these levels associated with dietary intake in Japanese adolescent football players. cross-sectional included 120 male Over 24 h, urine was collected measured creatinine, sodium, potassium levels. A assessment performed using sel...
