awareness of the presence of the accessory renal artery in kidney transplant, treatment of renal artery stenosis, clinical assessment of renal vascular hypertension, radiology and angiography interventions is very helpful. in 30% of cases the accessory renal artery is separated from the abdominal aorta and in most cases, this artery along with the main artery entered to the kidney through the h...

background: numerical study of angulation effects of renal arteries on blood flow has been of great interest for many researchers. objective: this paper aims at numerically determining the angulation effects of stenosed renal arteries on blood flow velocity and renal mass flow. method: an anatomically realistic model of abdominal aorta and renal arteries is reconstructed from ct-scan images and...

background. the major side effect of cisplatin, used in some tumours, is nephrotoxicity. reactive oxygen species and oxidative damage are the most important factors in cisplatin-induced acute renal failure. the main purpose of this study is to investigate the protective effects of crocin against cisplatin-induced acute renal failure and oxidative stress in rat. methods. in this study, animals w...

introduction: the selection of   optimal treatment of obstructive nephrouropathy requires information about the functional status of each kidney. nuclear renal scanning objectively measure differential renal function, multiple studies have demonstrated the role of assessment of renal perfusion and gfr with triphasic ct. the aim of this study is to assess the role of ct based on renal parenchyma...

introduction: renal length measurement is an important diagnostic clue in several urinary tract abnormalities. although ultra sonography is the most frequent used modality for renal size estimation, renal diameter assessment by 99mtc-dmsa scintigraphy is of great value. by now, pointing to the renal size in the 99mtc-dmsa scintigraphy report has not been recommended by guidelines. if the validi...

a 32 year old man underwent renal transplantation for the third time. this procedure was performed in december 1994, using the kidney of a living unrelated donor. the first transplanted kidney remained in the body after rejection but the second one was removed due to trauma. end-to-end anastomosis of the renal artery to the inferior mesenteric artery was performed and the ureter was reimplanted...

pheochromocytomas are cathecolamine producing tumor arising from chromaffin cells of adrenal medulla and extra adrenal tissues. this is a report of a boy presented with headache and hypertension. in radiologic exams, an adrenal mass detected in the left side, with no renal tissue on that side. it was reported an adrenal pheochromocytoma in histopathology. renal agenesis confirmed during surgery...

conclusions the severity of pathological changes in renal parenchyma, due to upjo, is a good predictor of renal function recoverability, after pyeloplasty. the orus, with drf > 35%, usually have normal (grade i) renal biopsy and might be expected to present better functional recoverability after pyeloplasty. results this study showed a linear relationship between the severity of histological ch...
