In this sense, ogstructiva should be taken into consideration that the glomerular fislopatologia is the result of a game of pressures which are established in the glomerular capillaries and the Bowman capsule, where in favor of the filtration we find the hydrostatic pressure of the capillary very important and the oncotic pressure of the Bowman capsule minimumwhile against it we find the oncotic pressure of the capillary considerable and the hydrostatic pressure of the Bowman capsule minimum.

The consequence of this last phenomenon is that it avoids the perfusion of the non-functioning nephrones by means of the redistribution of flow towards those who are functioning. In conclusion, since obstructive nephropathy is a potentially reversible cause of renal dysfunction, it should always be taken into account among the differential diagnosis of renal failure inducing mechanisms.

It is also stated that the damaged tubules release a chemotactic substance which would attract monocytes and macrophagues, which would infiltrate the renal parenchyma, damaging it by means of the local release of proteases and free radicals. Sign in via Shibboleth. Otherwise it is hidden from view. Independently of the place where the urinary obstruction happens, and from this moment, a series of events start to happen, which if they are not corrected can lead, in time, to irreversible renal damage and tubular atrophy.

In the case of intratubular obstructions uric acid, pigments, etc. An uro-obstruction can also cause hypertension which at its first stage in general is mediated by the activation of the renine-angiotensin-aldosterone system vasoconstriction and later, if a total obstruction occurs it is mainly due to water and salt retention hypervolemia. Curr Opin Nephrol Hypertens ; The latter can be subdivided into those which have intrinsic and extrinsic causes to the urinary tract Pop-up div Successfully Displayed This div only appears when the trigger link is hovered over.

Obstructive obstructivw can also lead to hypertension vasoconstriction-hypervolemiahyperkalemia, metabolic acidosis aldosterone resistancediabetes insipidus vasopressine resistance. Sometimes there is a rapture of the renal calices with the subsequent formation of urinomas. Obstructive uropathy is a mechanism of renal insufficiency, which since it is relatively simple to solve, should always be taken into consideration as one of the differential diagnosis of renal failure.

Likewise, the urinary obstruction can lead to a dysfunction of the distal nephron sectors resistance to aldosterone and vasopresinmaking it difficult for the local secretion of potassium and protons, as well as reducing the water reabsorption, thus facilitating the development of hyperkalemia, hyperchloremic metabolic acidosis and nephrogenic diabetes insipidus, respectively.
