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 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.

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

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.

Malignant Hypertension Following Renal Artery Branch Obstruction

JAMA, 1972
Occlusion of a renal artery branch with subsequent partial renal infarction resulted in high renin production from the ischemic part of the kidney and malignant hypertension. Absence of overall ischemia from the affected kidney prevented development of a pattern of increased concentration of nonabsorbable solutes (ie, creatinine and para-aminohippuric ...

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.

[Acute nontraumatic obstructions of the renal artery].

Presse medicale (Paris, France : 1983), 1985
Thirteen patients were operated on for acute obstruction of the main renal artery (17 kidneys at risk). The operation took place 18 hours to 36 days after the onset of the obstruction. Three nephrectomies were necessary, revascularization was possible in all other cases. Postoperative mortality rate was 15,4%, kidney salvage rate was 64,5%.

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 ...
