1/29. Ultrasonic demonstration of xanthogranulomatous pyelonephritis.An ultrasound examination performed on a young woman with a long history of urinary tract infection demonstrated multiple subcapsular sonolucencies suggestive of multiple abscesses. The combination of the ultrasonic appearance, the clinical history, and a large nonfunctioning kidney with calculi on intravenous pyelography allowed us to suggest the diagnosis of xanthogranulomatous pyelonephritis. Ultrasound plays an even greater role in patients who are allergic to iodinated contrast material in whom intravenous pyelograms and arteriograms may be contraindicated.- - - - - - - - - - ranking = 1keywords = pyelonephritis (Clic here for more details about this article) |
2/29. Cutaneous xanthogranulomatous inflammation: a potential indicator of internal disease.Cutaneous xanthogranulomatous inflammation is usually regarded as a primary disease process. We describe two patients with xanthogranulomatous pyelonephritis and nephro-cutaneous fistulae, one patient with xanthogranulomatous cholecystitis and a chole-cutaneous fistula and one patient with xanthogranulomatous appendicitis and appendiceal-cutaneous fistula. After the first case, awareness that cutaneous xanthogranulomatous inflammation can be secondary to related internal disease played a vital diagnostic role in the subsequent cases.- - - - - - - - - - ranking = 0.2keywords = pyelonephritis (Clic here for more details about this article) |
3/29. Xanthogranulomatous pyelonephritis in children.Xanthogranulomatous pyelonephritis in children, contrary to adult onset, rarely is associated with non-function or calcification. The lesion is predominantly on the left side in children. There appears to be a normal humoral but temporarily impaired cellular immune response in addition to sustained depression of polymorphonuclear chemotaxis. The etiology of this is uncertain but may be attributed partially to hyperosmolarity of serum and urine, and to leukocyte specific antinuclear antibodies. The presence of leukocyte specific antinuclear antibody or cold agglutining may interfere with normal phagocyte chemotaxis requiring tissue macrophages to produce a xanthogranulomatous reaction to bacterial invasion.- - - - - - - - - - ranking = 1keywords = pyelonephritis (Clic here for more details about this article) |
4/29. Xanthogranulomatous pyelonephritis masquerading as occult malignancy.Xanthogranulomatous pyelonephritis (XGP) can present with weight loss, anemia, leukemoid reaction, and generalized debility; there may be no signs or symptoms referable to the urinary tract. confusion between XGP and renal adenocarcinoma is well recognized, but other malignancies can also be simulated. Case histories of patients with proved XGP whose clinical presentations suggested occult malignancies are recorded. Proteus urinary tract infection, calculi, and a nonvisualizing kidney on intravenous pyelogram should suggest the correct diagnosis. The pathology, bacteriology, diagnosis, and treatment are reviewed.- - - - - - - - - - ranking = 1keywords = pyelonephritis (Clic here for more details about this article) |
5/29. Xanthogranulomatous pyelonephritis. A review with 2 case reports.Xanthogranulomatous pyelonephritis is a rather peculiar and rare form of chronic pyelonephritis and is usually caused by calculous urinary tract obstruction. The characteristic pathological finding is the presence of foam cells. We present 2 cases and give special attention to the clinical diagnosis and the phenomenon of nephrogenic hepatic dysfunction. A new series of 200 cases has been analyzed, and the most typical features of this inflammatory condition are compared with the findings in earlier series from the world literature.- - - - - - - - - - ranking = 1.2keywords = pyelonephritis (Clic here for more details about this article) |
6/29. Malakoplakia of the female genital tract.A rare case of malakoplakia of the uterine cervix and the pelvis occurring in an elderly woman who also had xanthogranulomatous pyelonephritis is described and compared with the 15 reported cases of malakoplakia of the female genital tract.- - - - - - - - - - ranking = 0.2keywords = pyelonephritis (Clic here for more details about this article) |
7/29. Xanthogranulomatous perinephritis: unusual cause of renal vein and vena caval thrombosis.Xanthogranulomatous pyelonephritis is an uncommon form of chronic renal infection which can be confused clinically, radiographically, and pathologically with renal carcinoma. Occasionally, xanthogranulomatous changes are more prominent in perinephric tissue than in the renal parenchyma itself. We present a case of locally invasive xanthogranulomatous perinephritis associated with thrombosis of the renal vein and inferior vena cava. With this constellation of findings, infections as well as malignant etiologies should be considered in the differential diagnosis.- - - - - - - - - - ranking = 0.2keywords = pyelonephritis (Clic here for more details about this article) |
8/29. Computed tomography of xanthogranulomatous pyelonephritis.The computed tomography findings in two cases of xanthogranulomatous pyelonephritis are presented. There was diffuse involvement of the kidney in one case, with correlation with the pathologic specimen and microscopic findings. In the second case there was focal involvement of the kidney. Computed tomography greatly assisted in making a correct preoperative diagnosis and in assessing the degree of extrarenal involvement.- - - - - - - - - - ranking = 1keywords = pyelonephritis (Clic here for more details about this article) |
9/29. Xanthogranulomatous pyelonephritis (XGP): a local disease with systemic manifestations. Report of 23 patients and review of the literature.The clinical, pathological and radiographic findings of 135 cases of xanthogranulomatous pyelonephritis have been reviewed. It is a form of renal suppuration and obstruction most commonly seen in middle aged women although all ages and both sexes may be affected. There is no race predilection. Gram-negative organisms are usually present and bilateral involvement has not been reported. The most common offending organism is proteus mirabilis. Hepatic dysfunction is seen and appears to normalize with removal of the XGP process. Preoperative angiography may increase the accuracy of differentiating this disorder from hypernephroma and may aid the surgeon in planning his approach to kidney resection depending upon the staging of XGP. Chronic renal failure is not usually a feature of XGP and nephrectomy is curative without any incidence of recurrence.- - - - - - - - - - ranking = 1keywords = pyelonephritis (Clic here for more details about this article) |
10/29. Xanthogranulomatous pyelonephritis in renal transplant recipient.Xanthogranulomatous pyelonephritis is reported in the native kidney of a renal allograft recipient. Immunoglobulin deposition in the transplant kidney in the absence of cell-mediated rejection, accompanied by selective cultures showing escherichia coli from the native kidney, led to the diagnosis. Native nephrectomy resulted in resolution of the patient's chronic bacteriuria and creatinine elevation.- - - - - - - - - - ranking = 1keywords = pyelonephritis (Clic here for more details about this article) |
