Background: Hawthorn species decreases blood pressure and relaxes precontracted vessels. This study aimed at examining the antihypertensive effect and related mechanisms of hydroalcoholic extract of Crataegus azarolus subspecies aronia fruit in rats with renovascular hypertension.Methods: Six groups of male Sprague-Dawley rats, each containing 6 to 8 rats, were studied. The groups comprised of ...

An 82-year-old man was referred to the nephrology division due to a sudden increase in creatinine (from 0.7 to 1.6 mg/dL). Two months earlier, the patient had undergone endovascular treatment with stent implantation (WALLSTENT Endoprosthesis, Boston Scientific, Natick, USA) in the left common iliac artery for peripheral artery disease. A CT scan revealed left hydronephrosis (Picture 1). Dilatio...

Upper urinary tract obstruction results in tubulointerstitial fibrosis and a progressive decline in renal function. Although several inflammatory mediators have been implicated in the pathophysiology of renal obstruction, the contribution of tumor necrosis factor-α (TNF-α) to obstruction-induced fibrosis and renal dysfunction has not been thoroughly evaluated. To study this, male Sprague-Dawley...

Urethral obstruction may be caused by prostatic hypertrophy, urethral stricture, or encrustation of a urethral-catheter lumen. Bacteriuria often complicates these obstructions. The sequelae include fever, acute pyelonephritis, chronic renal inflammation, and death. We hypothesized that even brief obstruction of the urinary tract containing a nonvirulent bacterium would result in these complicat...

The objective of this study was to determine the chronology of changes in blood pressure in renalhypertension induced by solid plexiglass clips in rats. Saw blades with the thickness of 0.21-0.22 mm wereused to make clips sized 4 × 2 × 2 mm from a piece of 2-mm thick plexiglass. Rats were subjected to shamoperation or left renal arterial clipping, and 1, 2, 3 and 4 weeks later blood pressure, a...

background multiple renal arteries in kidney grafts have been associated with an increased rate of vascular and urologic complications. our objective is to compare the outcome of transplanted patients who receive a single pedicle kidney with those who receive a multiple arterial graft. objectives to find our the differences in the outcome and complications in patients undergoing kidney transpla...

Hydronephrosis, "distension in varying degrees of pelvis and calyces, accompanied by progressive atrophy of renal parenchyma due to obstruction in urinary flow", is an apparently simple reno-urinary disease, but, in reality, by association of its own characters with those conferred by causative lesions, becomes of a significant complexity. The purpose of this paper is to demonstrate the pluriva...

The failure of blood flow to return to the kidney following a transient period of ischemia has long been recognized. The cause of this "no-reflow" has been investigated in the rat after a transient period of total obstruction of the renal arteries. The vascular pattern of the kidneys as visualized with silicone rubber injection shows a diffuse patchy ischemia throughout the kidney, which persis...

metastatic   tumors in the nose and paranasal sinuses are infrequent. the origin of this metastatic tumors are often renal cell carcinoma. we present one case of metastatic renal cell carcinoma   to the nose and paranasal sinuses ,4 years after initial nephrectomy and diagnosis of stage t1n0m0 clear cell carcinoma. the patient complained of nasal obstruction and recurrent epistaxis   who was tr...

Objective. To create a ureteral obstruction experimental model that can be proved through (99m)Tc-DTPA renal scintigraphy and histopathological studies, without causing total renal function loss. Materials and Methods. Ten New Zealand white rabbits were submitted to a surgical experiment to create a model of unilateral obstruction to urinary flow. Surgery procedure provided unilateral ureteral ...
