Tandem Ureteral Stents for Malignant Ureteral Obstruction

Journal of Endourology, 2020
Objectives: Malignant ureteral obstruction (MUO) is a devastating complication of cancer, and it is commonly treated by drainage via percutaneous nephrostomy (PCN). The objective of this study was to determine the efficacy, safety, and functional outcome of tandem ureteral stents (TUS) in the management of MUO.

Ureteral obstruction and segmental ureteral stents

Urologiia, 2022
Currently, 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, 1974
Summary 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 ...

Mitochondrial dysfunction and endoplasmic reticulum stress in the promotion of fibrosis in obstructive nephropathy induced by unilateral ureteral obstruction

Biofactors, 2020
Obstructive nephropathy favors the progression to chronic kidney disease (CKD), a severe health problem worldwide. The unilateral ureteral obstruction (UUO) model is used to study the development of fibrosis.

Transient Ureteral Obstruction After Ureteral Stenting

Journal of Urology, 1982
Transient 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, 2013
Unilateral 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.

Diagnostic utility of ultrasonography for detection of the cause and location of ureteral obstruction in cats: 71 cases (2010-2016).

Journal of the American Veterinary Medical Association, 2019
OBJECTIVE To assess the utility of ultrasonography to detect the cause and location of ureteral obstruction in cats and to identify factors associated with agreement between ultrasonographic and surgical findings.

Human umbilical cord‐derived mesenchymal stem cells conditioned medium attenuate interstitial fibrosis and stimulate the repair of tubular epithelial cells in an irreversible model of unilateral ureteral obstruction

Nephrology, 2018
The growing number of patients suffering from chronic renal disease (CKD) is a challenge for the development of innovative therapies. Researchers have studied the therapeutic effects of cell therapy in acute kidney injury (AKI).
