... of SNa correction and in 12 patients (6 women and 6 men) before and after 3 months of SNa correction by a vaptan or urea. Results: We confirm a low urine creatinine and solute excretion only in patients with chronic hyponatremia (>1 month). Correction of SNa (from 127 ± 2.3 mEq/L to 139 ± 2.8 mEq/L...

CKD can negatively affect beta cell function through increased levels of urea that reduce beta cell glucose utilization and impair insulin secretion, and possibly also through factors other than urea. It remains to be investigated whether urea and other factors of CKD can also affect...

...M.L. Halperin; M. Gowrishankar; J.P. Mallie; H. Sonnenberg; M. Oh Urea absorption in the inner medullary collecting duct provides a mechanism to elevate the concentration of urea in the papillary interstitial fluid and thereby permit the excretion of urea with as little water as possible. Urea...
