PURPOSE To determine the role of duplex Doppler ultrasonography (DDU) in patients with acute unilateral renal obstruction. SUBJECTS AND METHODS A total of 161 patients with suspected renal colic due to urolithiasis were evaluated by DDU followed by intravenous urography (IVU). The mean intra-arterial resistive index (RI) and the difference of mean resistive index between both kidneys (delta R...

A 34-year-old diabetic patient underwent a renal transplant which was complicated by right side lower extremity paresis and numbness with gluteal necrosis. The main reason was ligation of internal iliac artery of the same side as a result of extensive microvascular obstruction due to severe atheromatous plaque. This is a rare complication which is mostly reported in aneurysmal patients after by...

Superior Mesenteric Artery (SMA) syndrome is a condition in which the duodenum becomes compressed between the SMA and the aorta, resulting in bowel obstruction which subsequently compresses surrounding structures. Pressure on the inferior vena cava (IVC) and aorta decreases cardiac output which compromises distal blood flow, resulting in abdominal compartment syndrome with ischemia and renal fa...

Facticious accumulation of the radiopharmaceutical in the urinary draining system as shown by routine renal tests, like technetium- 99m-diethylenetriamine pentacetic acid, technetium-99m-mercaptylacetyltriglycine or technetium-99m-glucoheptonate renograms can be re-evaluated by administering a diuretic, like furosemide (FS) and obtaining post FS dynamic and static images. Urinary tract obstruct...

Genome-wide association studies have shown that variants in fat mass and obesity-associated (FTO) gene are robustly associated with body mass index and obesity. These FTO variants are also associated with end stage renal disease and all-cause mortality in chronic kidney diseases. However, the exact role of FTO in kidneys is currently unknown. Here we show that FTO expression is increased after ...

arteritis due to strongylus vulgaris is a well-known cause of colic in horses and donkeys. the current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by s. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial o...

OBJECTIVE The aim of our study was to evaluate a three-dimensional gadolinium-enhanced breath-hold MR angiography sequence using standard MR gradients in detecting renal artery stenosis. SUBJECTS AND METHODS Forty-two patients referred for angiography for suspected renal artery stenosis underwent both conventional digital subtraction angiography (DSA) and MR angiography. MR angiography was pe...
