Klahr S, Morrissey J.: Obsyructiva R, Flores D: Sign in via Shibboleth. Intratubular hydrodynamic forces influence tubulointerstitial fibrosis in the kidney. Nevertheless, if the obstruction is sustained in time, it leads to intrarenal vasoconstriction with the subsequent reduction in the glomerular blood flow. Am J Physiol Renal Physiol ; Curr Opin Nephrol Hypertens ; Increase in detrusor wall thickness indicates bladder outlet obstruction BOO in men.

Hospital Italiano de Buenos Aires. Clinical Sports Medicine Collection. Am J Physiol Renal Physiol. Transurethral prostate resection in patients with hypocontractile detrusor–what is the predictive value of ultrastructural detrusor changes? 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 severe and prolonged urinary obstructions, the renal parenchyma is reduced to a thin ring of atrophic tissue mainly as a consequence of the ischemia suffered by its continuous hyperfusion. Comment of the reviewer Jesus Garrido MD.

Sometimes there is a rapture of the renal calices with the subsequent formation of urinomas. J Clin Invest uroptia Search Advanced search allows to you precisely focus your query. Int J Mol Med.

Factors determining the amount of residual urine in men with bladder outlet obstruction: It is worth mentioning that hydronephrosis is the expansion of the pelvis and renal calyces proximal to the obstruction point; and that expansion is not always synonym of obstruction, since there are non-obstructive types of expansion known as ectasias 1 Tabla 1 Physiopatology The effect of bladder outlet obstruction treatment on ultrasound-determined bladder wall thickness.

In general, this condition known as post desobstructive poliuria, usually self-constraints in three days and does not extend for longer than a week. Servicio de ayuda de la revista. Obstructive nephropathy can also lead to hypertension vasoconstriction-hypervolemiahyperkalemia, metabolic acidosis aldosterone resistancediabetes insipidus vasopressine resistance.

This div only appears when the trigger link is hovered over. Usually glomerular hydrostatic pressure is largely predominant, obatructiva whom the net ultrafiltration pressure depends almost completely.

This phenomenon could be mediated by the release of angiotensin II and tromboxane by the obstructed nephrons. After an obstruction has settled, there is an increase in the pressure corresponding to its proximal section, due to the effect of the net fisiopato,ogia filtration pressure, which fisioparologia to an increase in intraluminal pressure, that carries a progressive expansion of the ureter as a compensating mechanism ley de la Lapacethus the significant difference of pressure between the ureter in a state of contraction and at rest is reduced, resulting in an ineffective ureteral peristalsis.

Cystometric parameters and the activity of signaling proteins in association with the compensation or decompensation of bladder function in an animal experimental model of partial fisiopqtologia outlet obstruction.

In the same way, when such obstruction is located in any point between the renal pelvis and the distal end of the urethra, it receives the more specific name of obstructive uropathy.

Likewise, the urinary obstruction can lead to a dysfunction of the distal nephron sectors resistance to aldosterone fisiiopatologia 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.

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.

There are many renal dysfunction inducing mechanisms involved in this entity:
