1. Intermittent claudication and severe renal artery stenosis are independently associated in hypertensive patients referred for renal arteriography
OBJECTIVE: The purpose of this study was to evaluate the association between the presence of clinical symptoms of peripheral artery disease and severe renal artery stenosis in patients referred for renal angiography. METHOD: We included 82 patients with clinical suspicion of renovascular hypertension and performed an imaging investigation (renal Doppler ul

2. Glomerular filtration rate measured by 51Cr-EDTA clearance before and after captopril administration: evaluation of hypertensive patients with and without renal artery stenosis / Medida da filtração glomerular determinada por EDTA-51Cr antes e após a administração de captopril: avaliação de pacientes hipertensos com ou sem estenose de artéria renal
INTRODUÇÃO: A hipertensão renovascular (HRV) decorrente da estenose de artéria renal (EAR) é uma patologia potencialmente curável, mas os benefícios da revascularização não são alcançados por todos porque selecionar pacientes com base nos critérios clínicos ou angiográficos pode não ser suficiente para se obter o sucesso clínico. Existe um g

3. Papel da nefrectomia do rim atrófico nos portadores de hipertensão renovascular / Effect of the nephrectomy of atrophic kidney in renovascular hypertension patents
Objective: to evaluate the beneficial effects of the Nephrectomy of atrophic kidney in patients with renovascular hypertension, on blood pression control and renal function. Methods: retrospective and observational study using data-base of 51 patients with refractory hypertension, atrophic kidney with significant stenosis or complete occlusion of renal arter

4. Localised pulmonary metastatic calcification associated with pulmonary artery obstruction.
BACKGROUND: Metastatic pulmonary calcification, a complication of uraemia and disordered calcium metabolism, may be diffuse or localised. The factors that determine calcium precipitation are complex, but tissue alkalosis is thought to be important. As obstruction of the pulmonary artery theoretically causes local alkalosis a retrospective necropsy study was

5. Thrombosis of the Renal Artery of a Small, Solitary Kidney: Successful Return of Renal Function after Prolonged Anuria
In the presence of a single functioning kidney, renal artery obstruction produces anuria, which can require hemodialysis. If the problem is diagnosed immediately and surgical intervention is not delayed, revascularization of the ischemic kidney is usually successful. Few authors, however, have reported the return of function to a small solitary kidney after

6. Pathogenetic role of Arg-Gly-Asp-recognizing integrins in acute renal failure. off.
Reorientation of the alpha 3 subunit of integrins from predominantly basal to the apical cell surface of cultured renal tubular epithelial cells subjected to oxidant stress has previously been demonstrated. The present study was designed to assess functional competence of ectopically expressed apical integrins. Cell-cell adhesion assay revealed enhanced cyto

7. The Role of Cell Swelling in Ischemic Renal Damage and the Protective Effect of Hypertonic Solute
The failure of blood flow to return to the kidney following a transient period of ischemia has long been recognized. The cause of this “no-reflow” has been investigated in the rat after a transient period of total obstruction of the renal arteries. The vascular pattern of the kidneys as visualized with silicone rubber injection shows a diffuse patchy isc

8. Living related kidney donors. A 14-year experience.
Living related donor (LRD) nephrectomies are controversial due to the risks to the donor and improved cadaveric graft survival using cyclosporine A. Between December 22, 1970, and December 31, 1984, 1096 renal transplants were performed at a single institution, 314 (28.6%) from LRD. The average age was 34.3 years (range: 18-67); none had preoperative hyperte
