The Pathophysiology of Ureteral Obstruction
Journal of Endourology, 1993Ureteral obstruction can have a variety of causes intrinsic or extrinsic to the kidney. The effects of obstruction are examined from the perspectives of duration, severity, totality, and the presence of complicating factors. There is a difference in the postobstructive pathophysiology depending on whether one or both ureters were obstructed.

Ureteral obstruction and hypertension
The American Journal of Medicine, 1970Two patients with unilateral ureteral obstruction presenting as hypertension are described. The experimental work relating hyperension, hydronephrosis and ureteral obstruction is briefly discussed. Procedures designed to relieve obstruction as opposed to nephrectomy should be considered in cases of prolonged ureteral obstruction, with or without ...

Management of ureteral obstruction
Veterinary Clinics of North America: Small Animal Practice, 2004The most common cause of ureteral obstruction in dogs and cats is ureteral calculi. Common clinical signs associated with ureteral obstruction include abnormalities in urination, persistent urinary tract infection, abdominal pain, vomiting, anorexia, weight loss,and depression or lethargy.

Ureteral Obstruction by Endometriosis
Urologia Internationalis, 2010The clinicopathological features of 2 cases of ureteral endometriosis are presented. The difficulties in diagnosis and surgical management of ureteral endometriosis are discussed. We emphasized the importance of frozen section during surgery for the lower one third of ureteral obstruction in premenopausal woman.

Procidentia and Ureteric Obstruction
British Journal of Urology, 1975Summary 3 cases of renal failure, due to procidentia, presenting as emergencies are described. The upper urinary tracts of 4 asymptomatic patients with procidentia were investigated; dilatation was found in 1 instance only. We would like to thank Miss A. Bigby and Mr Harron Thomson for allowing us to study the latter

Experimental Ureteric Obstruction
British Journal of Urology, 1974Summary Renal function during and after release of a short period (less than 2 hours) and following release of a long period (6 hours) of total ureteric obstruction in the rat was studied in 2 series of experiments. Ureteric end pressures were found to be significantly higher in diuretic compared to dehydrated rats ...

Ureteral Obstruction Promotes Ureteral Inflammation and Fibrosis
European Urology Focus, 2023Hydronephrosis and renal impairment may persist even after relieving an obstruction, particularly in cases of chronic obstruction. Obstruction can cause fibrotic changes of the ureter, potentially contributing to long-term kidney damage.To characterise pathophysiological changes of obstructed ureters with focus on inflammatory responses triggering ...

Transient Ureteral Obstruction After Ureteral Stenting
Journal of Urology, 1982Transient distal ureteral edema and obstruction have been recognized complications of retrograde ureteral catheterization for years. Similar changes in the proximal ureter may be induced by antegrade (percutaneous) ureteral intubation and are being more widely recognized as radiologists become more involved in upper urinary tract percutaneous ...

Unilateral ureteral obstruction: beyond obstruction
International Urology and Nephrology, 2013Unilateral ureteral obstruction is a popular experimental model of renal injury. However, the study of the kidney response to urinary tract obstruction is only one of several advantages of this model. Unilateral ureteral obstruction causes subacute renal injury characterized by tubular cell injury, interstitial inflammation and fibrosis.

Ureteral Stasis in Cervicoprostatic Obstructions
European Urology, 1980A urodynamic study of patients with prostatic adenoma or other types of cervicoprostatic obstructions demonstrate that ureteral stasis is not a consequence of a direct compression of the intramural ureter by the adenoma but is secondary to dynamic disturbances.
