Sometimes there is a rapture of the renal calices with the subsequent formation of urinomas. What happens during a complete and bilateral uro-obstruction is that the hydrostatic pressure of the Bowman capsule increases greatly, and it can even override the net ultrafiltration pressure and lead to obstructive renal failure.

Partial outlet obstruction in rabbits: Regarding the urinary obstruction uropatja, it is possible to divide them into those which are intra-renal intratubular and those which are extra-renal.

In conclusion, since obstructive nephropathy is a potentially reversible cause of renal dysfunction, it uropatiia always be taken into account among the differential diagnosis of renal failure inducing mechanisms. 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. A later resolution can mean partial or nule recovery, depending on the evolution time of the obstruction, the age uropqtia the patient and the degree of damage to the renal function previous to the obstruction.

Likewise, the urinary obstruction can lead to a dysfunction of the distal nephron sectors resistance to aldosterone and vasopresinmaking it difficult for the local fsiopatologia 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.

Search Advanced search allows to you precisely focus your query. Factors determining the amount of residual urine in men with bladder outlet obstruction: 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 tubular 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 obstfuctiva, 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.
