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. Could it be a predictor for bladder contractility?
Factors determining the amount of residual urine in men with bladder outlet obstruction: Accessed December 31, Curr Opin Nephrol Hypertens ; Obstructive nephropathy can also lead to hypertension vasoconstriction-hypervolemiahyperkalemia, metabolic acidosis aldosterone resistancediabetes insipidus vasopressine resistance.
Servicio de ayuda de la revista. Please enter User Name. Partial outlet obstruction in rabbits: 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. Obstruction-induced alterations within the urinary bladder and their role in the pathophysiology of lower urinary tract symptomatology.
View Table Favorite Table Download. Comment of the reviewer Jesus Garrido MD. 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.
Increase in detrusor wall thickness indicates bladder outlet obstruction BOO in men. Clinical Sports Medicine Collection. There are many renal dysfunction inducing mechanisms involved in this entity: The effect of bladder outlet obstruction treatment on ultrasound-determined bladder wall thickness. Obstructive nephropathy and renal fibrosis: In general, this condition known as post desobstructive poliuria, usually self-constraints in three days and does not extend for longer than a week.
Role of angiotensin II in chronic ureteral obstruction.

The latter causes polyuria which is characteristic of partial obstructive uropathy. The fate of urinary bladder smooth muscle after outlet obstruction–a role for the sarcoplasmic reticulum. In the case of severe and prolonged urinary obstructions, the renal parenchyma is reduced to a thin ring of atrophic kropatia mainly as a consequence of the ischemia suffered by its continuous hyperfusion.
Transurethral prostate resection in patients with hypocontractile detrusor–what is the predictive value of ultrastructural detrusor changes? Am J Physiol Renal Physiol.
A later resolution can mean partial or nule recovery, depending on the evolution time of the obstruction, the age of the patient and the degree of damage to the renal function previous to the obstruction. Search Advanced search allows to you precisely focus your query.
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. In the case of intratubular obstructions uric acid, pigments, etc. Chevalier RL and Cachat F.
Fisiopagologia latter can be subdivided into those which have intrinsic and extrinsic causes to the urinary tract After the resolution of a bilateral obstruction or a unilateral one in a patient with only one kidney, it is normal to find elevated serum levels of atrial factors, tubular resistance to vasopressin reduction of the expression of aquaporin 2 channels in the collecting tubules and compromise of the medullar tonicitydecrease in the fisiopxtologia reabsorption capacity of sodium and urea and presence of a free urinary tract, so the osmotic diuretic effect of the not reabsorbed urea and sodium starts to act, which increment diuresis finally leading to potassium, calcium, magnesium and phosphorus expoliation, which puts the patient at risk of having severe hydroelectrolytic depletion if these losses are not adequately monitored and treated.
