    Renal elasticity and perfusion changes associated with fibrosis on ultrasonography in a rabbit model of obstructive uropathy

    Hydronephrosis is a common disease involving distension and dilatation of the renal pelvis and calyces and is typically a result of obstruction of the free flow of urine from the kidney. Increased pelvic pressure in obstructive uropathy can damage …
