Urinary Phosphorous Excretion in Early Chronic Kidney Disease

Decrease in Urinary Creatinine Excretion in Early Stage Chronic Kidney Disease

BACKGROUND Little is known about muscle mass loss in early stage chronic kidney disease (CKD). We used 24-hour urinary creatinine excretion rate to assess determinants of muscle mass and its evolution with kidney function decline. We also described the range of urinary creatinine concentration in this population. METHODS We included 1072 men and 537 women with non-dialysis CKD stages 1 to 5, ...

Urinary sodium excretion and kidney failure in non-diabetic chronic kidney disease

Current guidelines recommend under 2 g/day sodium intake in chronic kidney disease, but there are a few studies relating sodium intake to long-term outcomes. Here we evaluated the association of mean baseline 24-h urinary sodium excretion with kidney failure and a composite outcome of kidney failure or all-cause mortality using Cox regression in 840 participants enrolled in the Modification of ...

Changes in urinary potassium excretion in patients with chronic kidney disease

BACKGROUND Hyperkalemia is one of the more serious complications of chronic kidney disease (CKD), and the cause of potassium retention is a reduction in urinary potassium excretion. However, few studies have examined the extent of the decrease of urinary potassium excretion in detail with respect to decreased renal function. METHODS Nine hundred eighty-nine patients with CKD (CKD stages G1 an...

Urinary Protein Biomarkers in Chronic Kidney Disease

Chronic kidney disease (CKD) is increasingly recognized as an important national and worldwide public health problem because of its consequences on quality of life and high prevalence, existing in up to one-tenth of the adults in developed countries and 13% of the general population [1,2]. Currently used diagnostic and staging tools are mostly based on non-invasive analysis of serum creatinine ...
