superior mesenteric artery syndrome is a very uncommon disorder in which acute angulation of superior mesenteric artery (sma) at its origin from aorta results in compression of the third part of the duodenum leading to partial or complete obstruction of the duodenum. other terminologies for this condition are cast syndrome, wilkie syndrome, arteriomesenteric duodenal obstruction, and chronic du...

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...

A seven-year-old stallion with diversion of urinary pass to the thigh due to a urethral fistula caused by gunshot perineal injury was presented to the Urmia University, Veterinary Teaching Hospital. No signs of urinary obstruction or renal failure were observed. Because of inaccessible location of the injured urethra, through a perineal urethrotomy incision, a urinary catheter was effectively a...

Upper urinary tract obstruction is a common cause of renal dysfunction in children and adults. While there is clinical evidence of an increased male incidence and mortality rate with acute renal failure, the effect of gender and testosterone on obstructive renal injury has not previously been evaluated. We hypothesized that testosterone exacerbates proinflammatory TNF-alpha production and proap...

PURPOSE To review the use of repetitive stenting in the management of patients with ureteral obstruction after renal transplantation, with an emphasis on technique and functional graft outcome. MATERIALS AND METHODS Five adult renal allograft recipients with ureteral obstruction were managed with repetitive ureteral stenting. Their hospital records, office notes, and operative reports were re...

Instruction: Measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. It is known that the artery diameter is increased by flow stimulation. Therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was assessed. Also the biomechanical behavior of th...

INTRODUCTION Rectus sheath haematomas associated with anticoagulation are often self limiting. When large, however, they can even extend into the pelvis and cause compression of adjacent organs such as the bladder. A combined endovascular and surgical approach can decrease the operative exposure necessary to treat this occurrence. REPORT A 42 year old morbidly obese African American female on...

The classical work of Goldblatt (1934 and 1937) and of Wilson and Byrom (1939), demonstrating the development of hypertension following unilateral renal ischmmia and the return of the blood pressure to normal following removal of the renal lesion, gave a great stimulus to the clinical study of hypertension. As a result it is clear that in man, as in the experimental animal, renal ischemia gives...
