Abstract Introduction: To determine whether preoperative computed tomography (CT)-based renal parenchymal volume (RPV) measurements would be predictive of postoperative chronic kidney disease (CKD).
Materials and methods: From 2005 to 2010, 189 patients with preoperative CT imaging performed at Emory University Hospital underwent renal tumor surgery. Preoperative and postoperative renal function was determined by estimating glomerular filtration rate (GFR) using standard Cockcroft-Gault (CG) and Modification of Diet in Renal Disease (MDRD) equations. Preoperative CT-measured RPV was calculated to determine the association of predicted preserved renal parenchyma with postoperative renal function and the development of CKD (GFR < 60 mL/min/1.73 m²).

Abstract Introduction: Contrast-enhanced cross-sectional imaging is essential to the urologist's practice. Traditionally, patients with impaired renal function could not be imaged with a computed tomography (CT) scan with contrast due to the risk of contrast-induced nephropathy (CIN). These patients could alternatively be imaged by magnetic resonance imaging (MRI) with gadolinium. However, the recent identification of the association between nephrogenic systemic fibrosis (NSF) and gadolinium administration has created significant challenges for urologists and radiologists when faced with the need for evaluation with contrast-enhanced cross-sectional imaging. In this review, we summarize the most comprehensive articles discussing both NSF and… More >

Abstract The Synchrotron Radiation X-ray Computed Tomography (SR-CT) technique is a non- destructive detection technology which can give the in-situ observation of microstructure evolution of materials under the external field (e.g., high pressure, high temperature, electromagnetic field, intense radiation, etc.), and it has a significant application in the area of plants and crops, advanced manufacturing, advanced materials, biomedicine, mechanics, archaeology and so on.

Abstract We report the first case, to our knowledge, of xanthogranulomatous pyelonephritis (XGP) with psoas abscess occurring during pregnancy. A 37-year-old woman in the third trimester of pregnancy presented with low back pain and a fever. From sonographic features, a multidisciplinary team decided to perform computed tomography of the abdomen with contrast agent injection, which strongly suggested diffuse XGP of the left kidney with a psoas abscess. Cesarean section at 32 weeks was followed by extended nephrectomy. Pathological examination of the operative specimen confirmed the diagnosis. Outcomes were favorable in the mother and baby. The diagnosis More >
