...). An estimated U osm (eU osm ) based on the concentrations of sodium, potassium, and urea, and a urine concentrating index (UCI) based on the ratio of creatinine concentrations in urine and plasma were compared to the measured U osm (mU osm ). Results: eU osm is an excellent surrogate of mU osm , with a highly...

... (TIME), and intradialytic exercise (EXER), 60 min of cycling at 90% of the lactate threshold in the last 90 min of HD. The primary outcome was eKt/V urea . Secondary outcomes included reduction and rebound ratios of urea, creatinine, phosphate and β 2 -microglobulin. Outcomes were calculated from blood...

... in critically ill patients. Urea, by inducing renal water excretion and promoting sodium (Na) retention, has been well described as a treatment for chronic SIADH. However, there are limited data on its use for the treatment of SIADH as encountered in patients admitted to the intensive care unit (ICU). We...

...Andre A. Kaplan; Orly F. Kohn The use of fractional excretion of sodium as a guide to renal perfusion is hampered by the prior use of natriuretic agents. The fractional excretion of urea (FEUr) has been shown to be affected by volume status. We, therefore, determined the value of the FEUr...

The concurrent studies by chemists of circulating and urinary levels of urea, creatinine, urate, phosphate, potassium, sodium and hydrogen ions expanded those correlations to a pathophysiological domain, especially in the late 19th and early 20th centuries. With the subsequent development...

...E. Kinne-Saffran; R.K.H. Kinne In 1828, Friedrich Wöhler, a German physician and chemist by training, published a paper that describes the formation of urea, known since 1773 to be a major component of mammalian urine, by combining cyanic acid and ammonium in vitro. In these experiments...
