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...

Preterm neonates are prematurely exposed to high oxygen levels at birth which may adversely impact ongoing renal development. The aim of this study was to determine the effects of neonatal hyperoxia exposure on renal function and morphology with aging. Sprague Dawley rat pups were raised in a hyperoxic environment (80% oxygen) from P3 to P10 during ongoing postnatal nephrogenesis. Control litte...

INTRODUCTION Our aim was to evaluate the result of simple renal cyst ablation by endoscope and compare the results with other techniques of renal cyst treatment. MATERIALS AND METHODS A prospective study was performed at Shaheed Faghihi hospital from January 2001 to January 2003. Ten patients with symptomatic simple renal cyst were selected for this study. The exclusion criteria were history ...

Transplantation of renal allografts inadequate to meet recipient metabolic demands has been hypothesized to be one cause of chronic allograft failure. This cohort study examined the relationship of each of three measures of recipient body size and one measure of recipient metabolic rate to the rate of allograft failure among 239 recipients of cadaveric renal allografts between 1985 and 1990. Al...

to minimize renal radiation in abdomical radiotherapy, shielding of the kidneys is essential. ivp-simulator is used as an standard method. in this study, we used 99mtc-dmsa to localize and shield the kidneys and we compared this method with ivp-simulator. the size of the kidneys was proven to be larger as compared with ivp method. the mean of the overlap percentage was 81.88 in right and 82.89 ...

OBJECTIVES To evaluate the incidence of simple renal cyst, the relationship between both size and location of cysts, and the effect on calyces; and to correlate symptomatology and effect on the pelvicalyceal system. METHODS Abdominal ultrasound examination was performed in 2010 patients for different reasons. Simple renal cysts were demonstrated in 110 patients harbouring 198 cysts. The cysts...

1. To determine whether variation in kidney morphology is associated with environmental aridity in South American hystricognaths, we used conventional and phylogenetic analysis (independent contrasts) to correlate mass-independent renal variables (kidney size; relative medullar thickness, RMT; medulla/cortex ratio, MC; inner medulla/ cortex ratio, MIC; relative medullar area, RMA) with environm...

OBJECTIVES To report the decline of renal function after radical nephroureterectomy (RNU) in upper tract urothelial carcinoma (UTUC) patients and to develop a nomogram to predict ineligibility for cisplatin-based adjuvant chemotherapy (AC). METHODS We retrospectively analyzed 606 consecutive Chinese UTUC patients treated by RNU from 2000 to 2010. We chose an eGFR of 60 and 45 ml/min/1.73 m(2)...
