unilateral obstructive uropathy

unilateral obstructive uropathy

Urology A disorder of blocked urine flow from the ureter of 1 kidney, resulting in backup of urine, distention of renal pelvis and calyces–hydronephrosis, and renal injury; abrupt blockage of a ureter causes acute UOU; progressive blockage causes chronic UOU Etiology Acute UOU–stones, trauma, congenital anatomic defects; chronic UOU–stones, local tumors or tumors from adjacent structures

In cases of ureteral obstruction, symptoms will present as a unilateral obstructive uropathy. Higher degrees of ureteral obstruction can then progress to hydronephrosis and renal failure.
Recoverability of renal function after treatment of adult patients with unilateral obstructive uropathy and normal contralateral kidney: a prospective study.
Untreated or undiagnosed unilateral obstructive uropathy in pets can lead to a self-perpetuating permanent renal damage and chronic renal failure, by inciting hydronephrosis, which causes pressure atrophy of the kidney tissue (Kahn et al., 2005; Vegad and Katiyar, 1998).
The present study was thus conducted to evaluate the architectural and functional changes in renal tissue in experimental models mimicking unilateral obstructive uropathy; and thus to ascertain the best correlation and degree of predictability of GFR values using gray-scale sonographic changes observed in the affected kidney, for futuristic convenience and success in monitoring progressive renal disease in dogs.
