Introduction: Renal transplantation has become the treatment of choice for most patients with end-stage renal disease. This involves recovering the kidney along with adequate vessel length from the donor and implanting it into the recipient anastomosing all vessels diligently. Usually “single renal artery kidneys” are preferred. However with the ever increasing waiting list of patients needing ...

Atherosclerotic renal artery stenosis affects between 2 and 4 million people in the United States alone and likely has a higher prevalence than previously thought. Renal artery stenosis has been increasingly recognized in recent years, especially in patients with cardiovascular disease. It has been associated with hypertension, renal dysfunction, and sudden onset of pulmonary edema. Patients wi...

In-stent restenosis of the renal arteries is relatively common and its management is not well studied. An 83-year-old female with bilateral renal artery stenosis and balloon angioplasty and stenting bilaterally one year ago was found to have recurrent severe elevations in the blood pressure despite medical management. Renal artery duplex showed 60-99% stenosis of the right renal artery and 20-5...

introduction: during kidney and other organ's transplantation, the organ to be transplanted, must inevitably remain out of the body with little or no blood perfusion at all, for long period of time (ischemia). this causes the release of oxygen free radicals (ofr). reperfusion (reintroduction of blood flow) will further exacerbate the initial damage caused by the ischemic insult and may result i...

To assess the accuracy of renal artery duplex scanning for the purpose of diagnosing atherosclerotic renal artery stenosis, we compared the findings of renal arteriograms to the results of duplex scanning in 41 patients. Using an increase of renal artery peak systolic flow velocity of greater than 180 cm/sec, duplex scanning was able to discriminate normal from diseased renal arteries with a se...

In humans, the kidney is involved in leptin clearance from the body. The present study was performed to assess the renal extraction of leptin in hypertensive patients with or without renal artery stenosis. Sixty-five hypertensive subjects (39 males and 26 females) underwent catheterization of the renal artery and both renal veins with blood sampling for measuring leptin levels. Blood flow to bo...
