Ureteral obstruction and segmental ureteral stents
Urologiia, 2022Currently, various types of stents are widely used in urological practice. One of the indications is the presence of upper urinary tract strictures. The factors leading to the development of strictures can be endogenous and exogenous, iatrogenic and non-iatrogenic, benign and malignant.

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 ...

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 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 ...

Bilateral Ureteral Obstruction
JAMA, 1964Dr. Dale E. Wenlund: This 63-year-old man was well until about one and a half years prior to the present admission, when he had a cholecystectomy. He subsequently noted a painful bulge in the region of the subcostal scar. Because of pain and anorexia, he lost 30 lb (1.36 kg) during the next 18 months and was unable to work.

Vascular Distal Ureteral Obstruction
Journal of Urology, 1975The diagnosis, treatment and results of 6 patients with 7 obstructed distal ureters secondary to vascular compression are presented. Three ureters were treated by transection of the offending vessels and the remaining 4 required additional ureteroneocystostomy.

Ureteral Obstruction During Pregnancy
Journal of Urology, 1984We report on a woman with recurrent renal failure due to bilateral ureteral obstruction during the mid trimester of pregnancy. The first pregnancy was terminated due to obstructive renal failure. In the second pregnancy renal function again deteriorated due to bilateral ureteral obstruction. After successful placement of a right ureteral catheter and a
