It freely crosses lipid membranes and is filtered into the glomerular filtrate in the renal glomerulus. A proportion of this filtered urea is reabsorbed passively before final excretion and it forms a vital of the concentration gradient needed to prevent passive diuresis.<br /> <br /> ==Clinical Significance==<br /> An increase in serum concentrations of urea and creatinine is known as '''[[Azotaemia|azotaemia]]''' and it is found almost exclusively in animals with kidney disease.<br /> <br /> Blood urea coentration may be elevated independently of creatinine for the following reasons:<br /> *Gastro-intestinal haemorrhage, as with [[Gastric Ulceration - Dog|gastro-duodenal ulceration]].<br /> *Diet with high protein or purine content, such as liver.<br /> *Increased catabolism of body tissues, particularly muscle, which may occur in pyrexic animals or those with systemic disease.<br /> <br /> Reduced urea concentration may occur due to:<br /> *Over-enthusiastic fluid therapy, diluting the urea present in the blood.<br /> *Disease that cause polyuria and/or polydipsia may cause 'medullary washout' of urea. Common examples include pyschogenic polydipsia, [[Diabetes Insipidus|diabetes insipidus]] and [[Hyperadrenocorticism|Cushing's disease]].<br /> *Reduced synthesis with [[Portosystemic Shunt|porto-systemic shunts]], [[Hepatic Microvascular Dysplasia|microvascular dysplasia]] or liver failure.<br /> *A diet with a low protein content or malnutrition.<br /> <br /> <br /> {{unfinished}}<br /> [[Categoría:Cambios Bioquímica de la Sangre]][[Category:To_Do_-_Blood]]<br /> [[Categoría:Cristina Castillo]]</div>
