1/9. A new cause of curvilinear renal calcification: calcified hydrocalycosis.Although many causes of curvilinear renal calcifications have been described, calcified hydrocalycosis mimicking hydatid cyst has not previously been reported. We report a case of hydrocalycosis which was appeared as a curvilinear calcified cystic lesion resulted from staghorn calculus associated with xanthogranolomatous pyelonephritis (XGPN) on intravenous pyelography (IVU) and computed tomography (CT).- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
2/9. Diffuse xanthogranulomatous pyelonephritis and staghorn calculus: report of one case.Xanthogranulomatous pyelonephritis and staghorn calculus are rare in children. In this report, we describe a Chinese boy without history of urinary tract infection who developed insidious onset of left flank pain. urine culture showed proteus mirabilis infection. Sonography and computed tomography of the abdomen showed typical picture of xanthogranulomatous pyelonephritis and staghorn calculus. photomicrography showed characteristic lipid-laden macrophage aggregates. After nephrectomy, he was symptom-free. In conclusion, xanthogranulomatous pyelonephritis should be considered in afebrile children with flank pain and staghorn calculus.- - - - - - - - - - ranking = 7keywords = calculus (Clic here for more details about this article) |
3/9. Focal xanthogranulomatous pyelonephritis associated with renal cell carcinoma.A case of focal xanthogranulomatous pyelonephritis (XGP) with an associated renal cell carcinoma is presented. The tumor was discovered incidentally during a general surgical procedure. Subsequent evaluation showed a 3 cm mass in the lower pole of an otherwise normal kidney with no evidence of calculus or infection. Radical nephrectomy revealed classic findings of focal XGP with coexistent clear cell carcinoma. The literature describing the rare association between these conditions is reviewed.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
4/9. Xanthogranulamatous pyelonephritis with psoas abscess: 2 cases and review of the literature.Xanthogranulomatous pyelonephritis (XGP) is a rare form of chronic pyelonephritis. With the review of the literature, we reported two cases of XPN with psoas muscle abscesses caused by Staphylococci aereus in one of the patient and serratia mascerentes in the other. Both of the patients had renal calculus. We performed nephrectomy with psoas abscess drainage and started appropriate antibiotics, but one of the patients died of septic shock. Other patient is free of symptoms at the end of 5 years follow-up.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
5/9. Renal tuberculosis simulating xanthogranulomatous pyelonephritis with contagious hepatic involvement.Xanthogranulomatous pyelonephritis (XGPN) is a chronic renal infection typically associated with nephrolithiasis and a non-functioning kidney. Renal tuberculosis is a major cause of morbidity in developing countries. Despite recent advances in diagnosis, it is sometimes difficult to differentiate renal tuberculosis preoperatively from XGPN. We present herewith a case report of a patient who was preoperatively diagnosed with a right non-functioning kidney due to renal calculus with stage 3 XGPN and adjacent liver abscess on computed tomography. Subsequent histopathological examination of the nephrectomised specimen revealed renal tuberculosis. To our knowledge this is the first case of renal tuberculosis spreading to the liver and causing liver abscess formation which was misdiagnosed as XGPN preoperatively.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
6/9. Ureteral involvement in stage I xanthogranulomatous pyelonephritis--(a case report).A case of xanthogranulomatous pyelonephritis (Stage-I: Nephric) with ureteral involvement is described. The patient had undergone right nephrectomy with the working diagnosis of calculus pyonephrosis and non-functioning kidney. Histopathological examination of the nephrectomy specimen revealed xanthogranulomatous pyelonephritis confined to the kidney and non-contiguous involvement of ureter. Post-operative recovery was uneventful and there had been no evidence of disease recurrence till one year's follow-up.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
7/9. Focal xanthogranulomatous pyelonephritis simulating a renal tumor: CT characteristics.Xanthogranulomatous pyelonephritis is the replacement of renal parenchyma by large lipid-filled macrophages clinically associated with an enlarged, nonfunctioning kidney containing a calculus in the diffuse form or tissue destruction in one pole of a duplicated kidney associated with a calculus in the focal form. We report a case where a focal mass in a functioning kidney with no evidence of calculus, duplication, or fat density simulated a primary renal tumor.- - - - - - - - - - ranking = 3keywords = calculus (Clic here for more details about this article) |
8/9. CT findings in xanthogranulomatous pyelonephritis with coexistent renocolic fistula.A case of diffuse xanthogranulomatous pyelonephritis of the kidney with an associated renocolic fistula is reported. Computed tomography demonstrated typical findings with an enlarged poorly functioning kidney with multiple near-water-density masses replacing the renal parenchyma surrounding a central staghorn calculus. A mottled gas collection within the renal parenchyma was secondary to a renocolic fistula rather than a pyogenic abscess.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
9/9. Focal xanthogranulomatous pyelonephritis simulating malignancy in children.Xantogranulomatous pyelonephritis is a severe chronic form of renal parenquimal infection that usually results in diffuse renal destruction. An unusual case of xanthogranulomatous pyelonephritis in a child is reported which presented as a focal mass without calculus in a functioning kidney and was diagnosed as a renal tumor.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
