STUDIES ON PARTIAL URETERAL OBSTRUCTION IN DOGS

Ureteral Obstruction in Dogs and Cats

71 Ureteral Obstruction IntRoduCtIon The ureters are fibromuscular ducts carrying urine from the kidney to the urinary bladder by peristaltic activity, which is transmitted from one muscle cell to the next (1). The ureters originate in the renal pelvices and travel retroperitoneally along the aorta and vena cava towards the urinary bladder. Near the pelvis they join the lateral ligament of the ...

Renin-angiotensin system and unilateral ureteral obstruction

Unilateral ureteral obstruction (UUO) is a clinical scenario that leads to obstructive nephropathy. UUO alters the expression of many mediators in the ipsilateral kidney. Renin-angiotensin system (RAS) is involved in UUO. Angiotensin II (Ang II) and angiotensin 1-7 (Ang 1-7) as the main arms of RAS influence kidney function which may alter by UUO. Ang II via Ang II receptor subtypes I (AT1R) ...

Renal Unilateral Partial Ureteral Obstruction ( PUO ) Research Literatures

Obstructive uropathy is a condition in which the flow of urine is blocked. This causes the urine to back up and injure one or both kidneys. Obstructive uropathy occurs when urine cannot drain through a ureter. Urine backs up into the kidney and causes it to become hydronephrosis. This article introduces recent research reports as references in the renal unilateral partial ureteral obstruction (...

Cardiopulmonary effects of partial pulmonary arterial obstruction in dogs.

Major obstruction to pulmonary artery blood flow such as occurs in massive pulmonary embolism is usually accompanied by a sharp decline in arterial blood oxygen tension. This phenomenon has long been recognized, and over 25 years ago Mendlowitz suggested that it was due to a decrease in the permeability of the alveolar-capillary membrane to oxygen transfer." Later Turino and his associates stat...
