“…Thickening of bridging septa in the perinephric space and thickening of the renal fascia are frequently present. A suburothelial hematoma appears as high-attenuation thickening of the wall of the renal pelvis and ureter (54,55). Hemorrhage into the renal sinus appears as a mass in the renal sinus with mass effect on the adjacent renal pelvis (Fig 12) (56).…”

“…The prevalence of spontaneous hemorrhage among patients receiving intravenously administered heparin (4.3%-6.6%) is higher than that among patients receiving orally administered anticoagulants (0.1%-0.6%) (52,53). Hemorrhage as a complication of anticoagulant therapy can be found in the perinephric space, suburothelium or subepithelium (54,55), and renal sinus (56). The urinary tract may be a site of bleeding in up to 40% of patients receiving anticoagulants (57).…”

Computed tomography (CT) plays an important role in evaluation and management of primary renovascular disease. Nonenhanced CT is useful for demonstrating renal hemorrhage, renal parenchymal or vascular calcifications, and masses. Contrast material-enhanced CT is essential to identify global or regional nephrographic abnormalities resulting from the vascular process (eg, renal infarcts, ischemia secondary to renal artery stenosis, arteriovenous communications). In addition, renal manifestations of a systemic disease (eg, vasculitis, thromboembolic disease) can be seen at CT. In trauma, occlusion of the main renal artery can be accurately diagnosed with contrast-enhanced CT. In cases of spontaneous renal hemorrhage without an apparent cause (eg, vasculitis, coagulopathy), a careful CT study should be performed to exclude renal cell carcinoma. The presence of fat in a hemorrhagic renal mass larger than 4 cm in diameter is characteristic of angiomyolipoma complicated by hemorrhage. Acute renal vein thrombosis appears as a clot in a distended renal vein, whereas renal vein retraction with collateral vessels is highly indicative of chronic thrombosis. Helical CT, especially with multiplanar two-dimensional and three-dimensional reconstruction following an intravenous injection of iodinated contrast material, has greatly improved our ability to directly image the proximal renal arteries and detect vascular lesions.

“…In anticoagulated patients, overall mortality from retroperitoneal hemorrhage is 20% (2). Thrombocytopenia is another factor exacerbating retroperitoneal hemorrhage (9). Thrombocytopenia in the present case was caused by septicemia and resultant disseminated intravascular coagulation syndrome.…”

Retrievable Guenther Tulip Filter Complicated by Sepsis and Retroperitoneal Hemorrhage: Successful Management by Filter Retrieval

et al. 2005

We encountered complications of septic shock and retroperitoneal hemorrhage which occurred after implantation of a retrievable Günther Tulip filter. A 79-year-old woman was diagnosed as right femoral vein thrombosis, and a retrievable Günther Tulip filter was deployed prior to a total knee replacement surgery. However, the patient developed septicemia due to Citrobacter freundii, followed by thrombocytopenia and retroperitoneal hemorrhage. A large hematoma was formed along the lateral side of the filter struts. We considered that the filter should be removed to control retroperitoneal hemorrhage and prevent secondary infection of the hematoma. Removal of the retrievable filter was effective in managing these complications.

“…2 There is an increased incidence of bleeding in anticoagulated patients ranging from 4 to 24%, 5 with the urinary tract bleeding complications being the most frequent, documented in up to 40% of the patients receiving longterm anticoagulant therapy. 6,7 The location of the bleeding can be intrarenal (also called pseudotumor), subcapsular, perinephric, pararenal, intraluminal, and rarely intramural on the wall of the renal pelvis, the ureter, and the urinary bladder. 5,7 The patient whom we present did not have any type of anticoagulant therapy.…”
