background: atherosclerotic renal artery stenosis (aras) remains underdiagnosed due to its nonspecific demonstrations. we aimed to both estimate the frequency of aras in high-risk non-selected patients undergoing simultaneous coronary and renal catheterization and possibly identify a predictive model for aras using baseline clinical, laboratory, and coronary angiographic variables. methods: the...

introduction: osteodystrophy is one of the long term complications of chronic renal failure and is expressed in two formslow turn over and high turn over. it is an important cause of morbidity in patients with renal failure and if diagnosed and managed properly, many problems of these patients can be resolved. in this study we evaluated the prevalence of hyperparathyroidism in hemodialysis pati...

BACKGROUND Replicative senescence, associated with telomere shortening, plays an important role in aging and cardiovascular disease. The relation between telomere length, cardiovascular risk, and renal disease is unknown. METHODS Our study consisted of a cohort of 257 kidney donors for transplantation, divided into a test and a validation cohort. We used quantitative RT-PCR to measure relativ...

The striking emergence of an epidemic of HIV-related renal disease in patients with end-stage renal disease provided the rationale for the exploration of whether HIV-1 directly infects renal parenchymal cells. Renal glomerular and tubular epithelial cells contain HIV-1 mRNA and DNA, indicating infection by HIV-1. In addition, circularized viral DNA, a marker of recent nuclear import of full-len...

OBJECTIVE To establish reference curves for size and volume of the fetal kidney, renal pelvis and adrenal gland, as measured using ultrasound from the 15(th) week of gestation. METHODS This was a prospective, longitudinal study of 96 fetuses in low-risk singleton pregnancies, in which we performed serial ultrasound examinations at 4-week intervals. The length and anteroposterior and transver...

INTRODUCTION The broad range of medical images and image processing technologies are applied in urology. The aim was to propose methodology to assess three-dimensional (3D) arrangement of renal arterial tree and to build a statistical model for analyzing the layout of arteries in the sections of the kidney. METHODS The series of kidney CT slices are analyzed using image processing procedures ...

A transitional zone in the dog renal artery was documented and its parameters were recorded: length and volumes of the luminal wall, tunica intima, tunica media, and tunica adventitia—as well as these parameters in the nontransitional zone of artery. Twelve normal adult male dogs were studied. Th e specimens were processed in the routine manner for light and electron microscopy. Aft er the dete...
