Nevertheless, if the obstruction is sustained in time, it leads to intrarenal vasoconstriction with the subsequent reduction in the glomerular blood flow.

Chevalier RL and Cachat F. 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.

This phenomenon could be mediated by the release of angiotensin II and tromboxane by the obstructed nephrons. 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 obdtructiva the local release of proteases and free radicals.

Usually glomerular hydrostatic pressure is largely predominant, on whom the net ultrafiltration pressure depends almost completely. In the case of intratubular obstructions uric acid, pigments, etc. Servicio de ayuda de hropatia revista. Data obtained from tests performed in animal models and information obtained from the evolution of clinical cases, suggest that the resolution of a complete obstruction before 8 weeks after it has settled can achieve a total recovery of the glomerular filtration.

In this sense, it should be taken into consideration that the glomerular filtration ruopatia 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.

Intratubular hydrodynamic forces influence tubulointerstitial fibrosis in the kidney. This site uses cookies to provide, maintain and improve your experience.
