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) ...
متن کاملPathophysiology of ureteral obstruction.
ROSE, JOHN G., AND JAY Y. GILLENWATER. Pathophysiology of ureteral obstruction. Am. J. Physiol. 225(4-j: 830437. 1973.Forty-five experiments measuring the force of contractility within the ureteral wall, its wall tension, and the propelling force within its lumen, its intraluminal pressure, were performed on 29 dogs. The parameters of wall tension and intraluminal pressure served as an excellen...
متن کاملGuidewire flow obstruction effect on pressure drop-flow relationship in moderate coronary artery stenosis.
To evaluate the local hemodynamic effects of coronary artery balloon angioplasty, computational fluid dynamics was applied to representative stenoses geometry post-angioplasty (minimal lesion diameter d(m) = 1.8mm which produced 64% mean area stenoses) based on a group of patients and measured values of coronary flow reserve (CFR) returning to a normal range (3.6+/-0.3). The computations were a...
متن کاملMalignant Ureteral Obstruction
A variety of pelvic, retroperitoneal or metastatic malignancies may cause ureteral obstruction either by direct invasion or external compression of the ureter. Ureteral obstruction is a cause of significant morbidity and mortality in cancer patients these patients may suffer from acute or chronic pain, acute renal failure or subacute impairment of renal function, and they are at risk for infect...
متن کاملSuccess of ureteral stents for intrinsic ureteral obstruction.
PURPOSE Previous reports suggest a high success rate for retrograde ureteral stenting for intrinsic ureteral obstruction, but few preoperative predictors of success have been offered. We reviewed our experience to look for factors that suggest failure of stents for intrinsic ureteral obstruction. MATERIALS AND METHODS We retrospectively reviewed the outcome of retrograde ureteral stent placem...
