The study on 6 cases of pyelonephritis of yellow granulatio at Hue Central Hospital showed a majority of female patients (2/3 of cases) aged 50-60 years old), having classic trilogy of great kidney with calculus and loss of function. Patients were admitted because of lumbago in 2/3 of cases. Urimia, fever and purulent fistula at lumbar side, each 1 case; large kidney touched in 1/2 of cases. Unprepared abdomen X ray image, UIV and ultrasound had found calculus in 1/2 of cases, 1/4 with pyhydrostasis, 3/4 loss of function. Especially color Doppler ultrasound found kidney arterio venous communicatio fistula in 1/2 of cases. CT scanning showed 6/6 cases with fat structure in the kidney parenchyma, 5/6 with large shade kidney, irregular border and heterogenous stain absorption.

There is no single characteristic clinical or radiological feature to diagnose xanthogranulomatous pyelonephritis, so it makes accurate preoperative diagnosis difficult. In our case, the renal parenchyme of affected kidney was well preserved on excretory urogram. The abnormal finding was only a filling defect within the right upper pelvocalyceal system. Herein we report a case of xanthogranulomatous pyelonephritis in a 18 years old girl which was confused with renal pelvic tumor.

Acute focal bacterial nephritis (AFBN), synonymous with acute lobar nephronia (ALN) or focal pyelonephritis, is an inflammatory mass without liquefaction caused by severe acute bacterial infection of kidney. Unless treated effectively, progression to a renal abscees may ensue. Clinically, AFBN presents as acute pyelonephritis, and radiologically, as focal swelling or mass. The distinction between AFBN and renal abceess or even tumor may be confusing and difficult. Ultrasonography and computerized tomography(CT) aid in establishing the correct diagnosis. However, the appearance of AFBN on sonography and CT is by no means pathognomonic. Benign or malignant renal tumors may have a similar appearance. With the clinical history, a high index of suspicion, and follow-up studies after institution of medical treatment may further aid in the differentiation. Herein we report 2 cases of AFBN, which were presented as renal masses.

Xanthogranulomatous pyelonephritis is an atypical form of severe chronic parenchymal infection and usually occurs in associated with urinary tract infection, obstruction and/or calculi. An accurate preoperative diagnosis is difficult because of its clinical and radiological similarities to various other renal lesions. We experienced two cases of xanthogranulomatous pyelonephritis, so we report with review of some literatures.

Authors reported a case of bilateral emphysematous pyelonephritis. Diagnosis is based on CT scan images of urinary system, or urography, and ultrasound of urinary system. This disease is a serious infection with high rate of death, usually occurs in diabetic patients, or in advanced stage. Treatment options are based on classifications according to CT scan, usually drainage of pus in pelvis renalis and bladder, and using antibiotics according to antibiogram. In unpreservable case, nephrectomy is applied. Healing is depended on severity and needs 1-5 years of follow-up.

Xanthogranulomatous pyelonephritis of the kidney usually occurs in association with urinary tract infection. obstruction and calculi. The diagnosis is made when a nephrectomy is performed for a nonfunctioning kidney or a mass indistinguishable from carcinoma. We experienced incidentally a case of xanthogranulomatous pyelonephritis. so the pathologic features and clinical presentation were discussed and the literature was reviewed.

Emphysematous pyelonephritis is a rare complication of acute pyelonephritis that occurs in diabetics or urinary obstruction and spontaneous gas formation around renal parenchyme. Diagnosis. in appropriate clinical setting. is confirmed radiographically. Plain film demonstrates a surprising pneumonephrogram, mottled gas shadow in the renal parenchyme as well as perirenal gas. Surgical intervention after unsuccessful antibiotics and conventional medical measurement is necessary. We experienced 3 cases of emphysematous pyelonephritis which occurred in diabetic women with brief review of the literature.

Emphysematous pyelonephritis is characterized by acute necrotizing renal parenchymal infection with gas formation. It is a serious, life-threatening infection that tends to occur in patients with diabetes mellitus and/or urinary tract obstruction. Early diagnosis and prompt intervention combined with surgical and medical treatment are required for survival. In Korea, there have been a number of cases of emphysematous pyelonephritis reported in patients with diabetes mellitus or urinary tract obstruction. We describe a case of emphysematous pyelonephritis in a patient without diabetes mellitus or urinary tract obstruction.

Emphysematous pyelonephritis is a rare complication of severe acute pyelonephritis and a suppurative infection of the renal parenchyma characterized by the production of gas by bacteria through fermentation. Emphysematous pyelonephritis occurs in patient with diabetes mellitus or urinary obstruction. We review the diagnosis and management of emphysematous pyelonephritis and report a case of emphysematous pyelonephritis developed in renal tuberculosis.

Xanthogranulomatous pyelonephritis is an atypical form of severe renal parenchymal infection, characterized by yellow lobulated masses macroscopically and massive inflammatory cell, foamy histiocyte microscopically. Preoperative diagnosis confused with hypernephroma, pyonephrosis with stone, other renal inflammatory disease. We report two cases of xanthogranulomatous pyelonephritis, diagnosed by microscopical finding and literature has been reviewed briefly.
