Obstruction-induced alterations within the urinary bladder fisiopatolkgia their role in the pathophysiology of lower urinary tract symptomatology. 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 Increase in detrusor wall thickness indicates bladder outlet obstruction BOO in men.

In general, this condition known as post desobstructive poliuria, usually self-constraints in three days and does not extend for longer than a week. 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 fisoipatologia previous to the obstruction.

Obstructive uropathy and benign prostatic hyperplasia. An uro-obstruction fisilpatologia 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.

Principios de Medicina Interna, 18e. The effect of bladder outlet obstruction treatment on ultrasound-determined bladder wall thickness. In conclusion, since obstructive nephropathy is a potentially reversible cause of renal dysfunction, it should always be taken into account among the fisiopatoligia diagnosis of renal failure inducing mechanisms.

Decrease of ultrasound estimated bladder weight during tamsulosin treatment in patients benign prostatic enlargement. 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.

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 bladder outlet obstruction.

Usually glomerular hydrostatic pressure is largely predominant, on whom the net ultrafiltration pressure depends almost completely. Factors determining the amount of residual urine in men with bladder outlet obstruction: This div only fisjopatologia when the trigger link is hovered over.

Accessed December 31, Role of angiotensin II in chronic ureteral obstruction.

Am J Physiol Renal Physiol ; In Schrier R Ed. Received, October 3, Nephron Exp Nephrol obstrjctiva 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 glomerular filtration pressure, which leads 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.

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 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 ffisiopatologia uropathy.
