We report a case of staghorn nephrolithiasis that evolved into xanthogranulomatous pyelonephritis with perinephric abscess, nephrobronchial fistula, and lung abscess. The patient was an intravenous drug abuser who tested positive for human immunodeficiency virus, without evidence of acquired immunodeficiency syndrome. He presented with a 2-month history of untreated repeated episodes of left flank pain and hyperpyrexia. Treatment involved left nephrectomy, debridement of abscess, tube drainage, and intravenous antibiotics. The patient illustrates the need to consider untreated nephrolitiasis as a predisposing factor for pulmonary complications.

A 51-year-old female exhibited fever, left flank pain and left flank mass in March, 1993. Drip infusion pyelography (DIP) revealed a non-functioning left kidney with shadows of calculi, and abdominal computerized tomography (CT) showed renal calculi and multilocular cystic lesions in the left kidney extending through the perinephric space into the mass on the left flank. Percutaneous nephrostomy and percutaneous drainage were performed, followed by left nephrectomy. Histopathological findings revealed xanthogranulomatous pyelonephritis. There have been a few case reports of xanthogranulomatous pyelonephritis forming nephrocutaneous fistula in the back.

A 51-year-old female patient was hospitalized in our department with high fever and left flank pain. Laboratory examination showed leukocytosis, increase of C-reactive protein (CRP), hyperglycemia and renal insufficiency. Enterobacter aerogenes grew out of the cultured urine. The radiograph and computerized tomographic (CT) scan revealed streaky gas in the destroyed left renal parenchyma with perirenal gas. She was diagnosed with left emphysematous pyelonephritis. Antibiotics therapy, treatment for sepsis and disseminated intravesicular coagulation was initiated resulting in mitigation of inflammation. High blood glucose initially required insulin therapy, but finally returned to normal levels through administration of oral antidiabetics. Although leukocytosis and low grade fever continued, the patient was discharged on day 53 with a negative CRP. CT scan indicated that the emphysematous change was localized after three months and almost resolved after four months. Renal scintigram indicated the residual function of the affected kidney. Because of the possibility of residual renal function and the cure by conservative therapy alone, the conservative therapy is preferred when the initial treatment is effective.

We present a case of a 30-year-old female who was evaluated for right flank pain. Clinical and diagnostic work up revealed a urinary tract infection with focal pyelonephritis of the right kidney. Ultrasound and computed tomography of the abdomen were included in the evaluation and revealed incidental finding of cystic structure at right suprarenal space. Follow-up evaluation for further characterization of cyst was performed with MRI and displayed a 4.8x4.5-cm right adrenal cyst containing dystrophic calcification, septations, and minimal nodularity. Surgical resection and histologic findings were compatible with cystic lymphangioma of the adrenal gland. Adrenal lymphangioma is a rare and benign lesion that is most often identified incidentally during radiological investigation or at autopsy. Diagnostic features of adrenal cysts including lymphangiomas are discussed.

The authors present a case of a young diabetic patient with acute symptoms of pyelonephritis. The specific and permanent antibiotic treatment was ineffective and septic condition developed complicated by renal papillary necrosis. Because of the strong flank pain extensive examinations were done with negative result. The patient's condition was improving only slowly and there was need for treatment after her discharge as well. Long-term antibiotic treatment is an effective therapy to cure this previously deadly complication. Special attention should be given to diabetic patients because of frequent urinary tract infection and increased risk of renal damage among them.

A 62-year-old woman visited our hospital complaining of fever and right flank pain. On excretory pyelography the right kidney containing three renal stones was not visualized. Retrograde pyelography revealed an irregular filling defect in the right renal pelvis. Computed tomography revealed renal stones and a tumor mass in the right renal pelvis. From these findings, the pelvic tumor of the right kidney complicated by renal stones was diagnosed. Right nephrectomy was performed. Because a fistula between the renal pelvis and the second portion of the duodenum was found in the operation, partial resection of the duodenum was also performed. Pathological diagnosis was adenocarcinoma of the renal pelvis and pyeloduodenal fistula due to chronic pyelonephritis. Postoperative chemotherapy was not given. This is the first case report of adinocarcinoma of the renal pelvis coexisting with a pyeloduodenal fistula.

Secondary amyloidosis is a relatively common pathology in which chronic infectious diseases are common causes, especially infected bronchiectasis, osteomyelitis or chronic ulcers. The association of xanthogranulomatous pyelonephritis and systemic amyloidosis is extremely rare. To our knowledge, despite innumerable cases of xanthogranulomatous pyelonephritis reported in the literature, this association has been reported in only 8 previous cases. Patients usually complain of fever, back or flank pain and urinary tract symptoms. A long lasting evolution of the process is frequent. We report a 70 year old patient who developed amyloidosis secondary to xanthogranulomatous pyelonephritis. As well as the rarity of this association, this case is exceptional in its clinical presentation, without any urinary tract symptoms that could suggest the diagnosis.

A 72-year-old non-diabetic uremic woman underwent right nephrectomy for urolithiasis at the age of 50. Because pyuria, fever, chilliness and left flank pain developed during preparing for arteriovenous fistula, she was admitted to National Cheng Kung University Hospital. Renal cell carcinoma (RCC) complicated with emphysematous pyelonephritis (EPN) was diagnosed and immediately treated with antibiotics and CT-guided percutaneous catheter drainage. Cultures of pus and blood yielded Escherichia coli. She received left radical nephrectomy later for the control of persistent sepsis and removal of left renal tumor. The pathology of the tumor was composed of a glandular arrangement of granular cells with the occasional atypism, and renal parenchyma had been totally replaced by RCC. The non-tumor part of the kidney showed chronic pyelonephritis. Five months later, multiple metastases developed. We reported this first uremic case with EPN and RCC, but without diabetes mellitus and urinary tract obstruction. The gas formation may be due to large RCC, which caused impaired tissue perfusion and E. coli infection.

A 34-year-old female with left flank pain persisting for 3 months consulted us on 19 Feb, 2001. Ultrasonography (US), computerized tomography (CT), magnetic resonance imaging (MRI) and renal angiography revealed a cystic renal tumor in the upper pole of the left kidney invading the spleen, and paraaortic lymph node swelling. Left radical nephrectomy combined with splenectomy and partial diaphragmectomy was performed under a tentative diagnosis of renal cell carcinoma. However, histopathological findings revealed xanthogranulomatous pyelonephritis (XGP). XGP is a rare, severe, chronic inflammatory disease characterized by accumulation of lipid laden macrophages. XGP is classified as diffuse or focal type. Preoperative diagnosis of focal XGP is difficult because of radiological similarities to renal cell carcinoma. Our case was more difficult to diagnose because she showed few signs of inflammation and had no history of urinary tract infection or stones.

This report describes a 56-year old woman with an unusual form of chronic pyelonephritis mimicking tuberculosis on histopathological findings. She visited our hospital complaining of left flank pain. Left staghorn calculus and retroperitoneal abscess extending from the kidney were demonstrated on CT. No bacteria, including mycobacteria were identified in preoperative urine bacterial culture. Left nephrectomy with drainage of retroperitoneal abscess was performed. Microscopically, the nephrectomy specimen showed caseating granulomas, formed by epitheloid cells, highly suggestive renal tuberculosis. In spite of these findings, acid-fast bacteria were not revealed in the renal lesion nor the abscess, and cultures of the abscess for mycobacteria were also negative. Because of failure of identifying Mycobacterium tuberculosis, this case should be diagnosed as not renal tuberculosis, but pseudotuberculous pyelonehritis, which has been mentioned in recent literatures. Although this disease is not widely recognized, we must be aware of it to avoid unnecessary antituberculous therapy.
