The detailed findings of canine intrarenal anatomy (collecting system and arteries) are presented. Ninety-five three-dimensional endocasts of the kidney collecting system together with the intrarenal arteries were prepared using standard injection-corrosion techniques and were studied. A single renal artery was observed in 88.4% of the casts. The renal artery divided into a dorsal and a ventral...

BACKGROUND Each kidney is supplied by a single renal artery and a single renal vein, which accounts for about 20% of the cardiac output. However, variations in the form of level of origin and arrangement of renal arteries are so frequent. AIM The present study aimed to note the vascular anatomy of kidneys with respect to the variations in their origin, course and any aberrant vessels which we...

Previously, it was shown that individuals with good baseline (a priori) endothelial function in isolated (in vitro) renal arteries developed less renal damage after 5/6 nephrectomy (5/6Nx; Gschwend S, Buikema H, Navis G, Henning RH, de Zeeuw D, van Dokkum RP. J Am Soc Nephrol 13: 2909-2915, 2002). In this study, we investigated whether preexisting glomerular vascular integrity predicts subseque...

There are often duplicated ureter with types of congenital anomalies and associated clinical complications. The unilateral duplicated ureter was observed as an incidence result in usual dissection. During routine dissection of the body of an adult male with middle-aged 40-50 year old, the duality of unilateral incompletely ureter was seen in above. Two branches of ur...

Introduction; Dynamic contrast MR angiography (C MRA) has made a major role for evaluation of cardiovascular diseases. For evaluation of patients with renal insufficiency or history with adverse reactions, MR contrast media cannot be used. Non-contrast (NC) MRAs with several techniques have been introduced. Currently, we used two types of MRA; FIESTA with flow preparation pulse (Flow-Prep) base...

Horseshoe kidney (HSK) is the most common congenital abnormality of the urologic system encountered during abdominal aortic aneurysm (AAA) surgery. Here, the authors report a case of AAA coexisting with HSK that was successfully treated by open surgery. Two accessory renal arteries of 2.5 mm and 3.1 mm were reimplanted. One of the implanted arteries later occluded and infarct of the isthmus dev...

During pregnancy, relaxin stimulates nitric oxide (NO)-dependent renal vasodilation, hyperfiltration and reduced myogenic reactivity of small renal arteries via the endothelial ETB receptor subtype. Our objective in this study was to elucidate the mechanisms by which relaxin stimulates the endothelial ETB receptor/NO vasodilatory pathway. Using chronically instrumented conscious rats, we demons...

To determine the nature of the flow in the proximal portion of the renal arteries, a common site for the development of atherosclerosis, we performed pulsatile flow studies in a clear acrylic mold of a normal human aorta and renal arteries. The mold was developed from a cast of the renal arteries prepared in situ during the autopsy of a 27-year-old woman. Flow in the mold was visualized by the ...

Segmental arterial mediolysis is a noninflammatory nonatherosclerotic vasculopathy of uncertain etiology characterized by dissection and/or aneurysm formation. It affects medium-to-large arteries, primarily the celiac, superior mesenteric, and renal arteries. Iliac involvement rare, its specific treatment has not been described. We detail patient who presented with intrabdominal hemorrhage from...
