Obstruction of the Renal Artery Producing Malignant Hypertension

New England Journal of Medicine, 1955
ONE of the most important recognized factors in the pathogenesis of hypertension is the role of the kidney. In spite of tremendous effort the mechanism by which hypertension is produced in renal disease has remained obscure. It is our purpose to report a case in which malignant hypertension was caused by an extrinsic compression of the right renal ...

Modification of the Howard Test for the Detection of Renal-Artery Obstruction

New England Journal of Medicine, 1960
IT has been known for many years that obstruction to one or both renal arteries in man could result in hypertension (the Goldblatt kidney). Many patients suspected of this disorder have, in the past, been subjected to nephrectomy, with little or no permanent improvement in their hypertension.

Relation of Superior-Mesenteric-Artery Obstruction to Renal Hypertension

New England Journal of Medicine, 1965
BLALOCK et al.1 demonstrated in dogs that unilateral renal-artery constriction resulted in a greater rise in blood pressure if the superior mesenteric artery was also previously constricted. Furthermore, in their animals the hypertension was sustained for at least one year, whereas Goldblatt and his associates2 had found that hypertension produced by ...

Therapeutic Ureteral Obstruction and Renal Artery Embolization

Journal of Urology, 1975
Two relatively unique techniques have been used in 4 cases to treat gross hematuria that might otherwise have resulted in nephrectomies. The techniques include ureteral obstruction with a Fogarty catheter and renal artery embolization.

RENAL ARTERY THROMBOSIS SECONDARY TO URETERAL OBSTRUCTION

Journal of Urology, 1999
Nephrolithiasis in patients with a solitary kidney can cause obstructive anuria. However, to our knowledge we report the first case of renal artery bypass graft thrombosis after acute ureteral obstruction in a solitary functioning kidney presenting with anuria. We propose that myogenically mediated renal artery hypoperfusion secondary to acute ureteral

RENAL ARTERY EMBOLIZATION FOR BENIGN OBSTRUCTIVE UROPATHY

Journal of Urology, 2001
We demonstrate safety of renal artery embolization as an alternative to nephrectomy in symptomatic patients with obstructed, poorly functioning kidneys who are unfit for surgery.We performed renal artery embolization in 2 medically unfit patients with benign obstructive uropathy and poorly functioning kidneys.

Obstruction of the Abdominal Aorta Above the Level of the Renal Arteries

Radiology, 1964
Obstruction of the abdominal aorta is an almost commonplace diagnosis today. Most of the cases reported in the literature occur in the lower aorta, particularly at the bifurcation (3). There have been many examples of aortic occlusion at the level of the renal arteries, but in most instances these were secondary to a “Leriche“ type of atherosclerotic ...

Renal Arterial Duplex Doppler Ultrasound in Dogs with Urinary Obstruction

Journal of Urology, 1991
Recent clinical studies using duplex Doppler sonography identified an alteration in renal arterial blood flow in obstructed hydronephrotic kidneys that reportedly can be used to distinguish obstructive from nonobstructive collecting system dilatation.

Ureteric Irregularity with Renal Artery Obstruction: A New Radiological Sign

The British Journal of Radiology, 1961
A case is described in which indentations of the upper ureter by anastomotic ureteric arteries on pyelographic examination constituted an indirect sign of renal artery occlusion. The blood supply of the ureter is considered and the part it plays in providing collateral channels in renal artery obstruction is discussed.
