A 48-year-old man was admitted to our hospital because of high fever and left flank pain. Laboratory findings revealed a high white blood cell count, high C-reactive protein level, and severe pyuria. Sonographic examination revealed an enlargement of the cyst at the upper pole of the left kidney that had already been detected. Percutaneous drainage was performed for the cyst and 60 ml of purulent fluid was obtained. Bacterial culture of the fluid was positive for Propionibacterium acnes and gamma-Streptococcus. The drainage and administration of povidone-iodine was continued for 7 days. The size of the cyst was reduced with disappearance of symptoms.

The present study demonstrates that renal tubular unresponsiveness to aldosterone, without associated hyperkalaemia, is present in children with acute pyelonephritis. We studied 32 children with a diagnosis of acute pyelonephritis established by high fever, flank pain/tenderness, increased blood levels of C-reactive protein and significant Escherichia coli growth in the urine culture. Renal tubular function tests and determinations of plasma renin activity and aldosterone concentration were performed at diagnosis (study 1), after three days of iv gentamycin (study 2) and after 21 days of antibiotic therapy (study 3). Findings were compared to those present in 32 normal children of similar age. Despite normal plasma potassium concentration, fractional potassium excretion and transtubular potassium concentration gradient were significantly decreased in studies 1 and 2, becoming normal in study 3. Decreased renal potassium excretion coexisted with increased values for plasma renin activity and aldosterone concentration. In study 3 these hormones remained elevated only in patients with scarred kidneys. The functional alteration present in acute pyelonephritis may be directly caused by the interstitial inflammation or be mediated by some E. coli endotoxin.

Computerized tomography was performed on 19 patients diagnosed as having uncomplicated acute pyelonephritis. The relationship was investigated among the laboratory findings, presence of flank pain, clinical course and severity of the lesions detected by computerized tomography. In patients febrile for less than 2 weeks healing as assessed by computerized tomography took an average of 76 days. However, in patients with repeated febrile episodes occurring for longer than 2 weeks healing was delayed until an average 232 days after onset. Computerized tomography findings generally correlated well with the erythrocyte sedimentation rate, C-reactive protein level, and presence of pyuria and flank pain. However, in patients with a prolonged course computerized tomography proved to be a more reliable indicator of progress than either the results of laboratory tests or the symptoms. In conclusion, computerized tomography was useful in the diagnosis, assessment of severity and evaluation of healing of acute pyelonephritis.

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.

A 59-year old female presented with right flank pain and hydronephrosis. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) before admission (August 2001), revealed a periureteral mass measuring 11 cm in length along the right ureter. Since the preoperative image examinations could not exclude a malignancy, she was admitted for surgery. After admission, however, she presented no abnormal findings in laboratory investigations including tumor markers, urinalysis, urine cytology and retrograde pyelography. C-reactive protein was normalized. CT after admission (September 2001), showed spontaneous regression of the mass. We cancelled the operation and decided to carefully watch this lesion by CT. The lesion continued to regress thereafter. Judging from the clinical course, we regard the mass as inflammatory pseudotumor although pathological diagnosis was not performed. The possibility of preserving the urinary tract in this disease is discussed by reviewing the previously reported inflammatory pseudotumor of the upper urinary tract.

Retroperitoneal fibrosis (RPF) is characterised by inflammatory fibrotic processes affecting the retroperitoneal structures. Its prevalence of 1 - 2/200,000 makes it a rare disease. To date, there are no guidelines for the diagnosis of or therapy for the disease. If untreated, the disease may be fatal. In 2006, the Department of Urology of the HELIOS Klinikum Wuppertal undertook to establish a nationwide patient registry, which would facilitate prospective therapy trials and the drafting of recommendations for diagnostic procedures. The pathogenesis of the disease is still unclear. Since some RPF-patients present with associated autoimmune diseases, autoimmune processes are suspected to play a role in causing the disease. The presence of autoantibodies and histological similarities with vasculitis support this hypothesis. Following initial general symptoms, patients display localised symptoms (flank pain, leg oedema, abdominal discomfort), caused by the displacing effect of the fibrotic plaques. Laboratory tests show elevated ESR and C-reactive protein and in some cases a moderate anaemia. Histological examinations should be undertaken to rule out the presence of malignant tumours. Radiological diagnostics (excretory urography, CT, MRI) show a retroperitoneal mass which blocks, compresses and displaces, completely or in part, the large vessels and the ureter. Initial therapy aims at restoring the function of the affected hollow organs through the application of (ureteric) stents, followed by immunosuppressive therapy. If drug therapy is unsuccessful, surgical procedures will follow to protect the ureter from compression. In some cases, ureteral replacement or an autotransplant of the kidney may be necessary. Life-long observation of the patients is necessary, as the disease may be chronic and relapsing. Interdisciplinary and nationwide cooperation is of crucial importance to further investigate this disease.

A 49-year-old man with a medical history of polycystic kidney disease was presented to the emergency department with fever and left flank pain. Abdominal examination revealed an enlarged and painful left kidney. The C-reactive protein level was significantly high and the magnetic resonance imaging revealed areas of abnormal intensity and fluid-fluid levels in renal cysts. Brucella abortus was yielded from both blood and cyst fluid culture. Standard therapy (rifampicin plus doxycycline) of brucellosis was started, but the clinical and laboratory signs subsided after the addition of ciprofloxacin. There was no need for aspiration of infected cyst fluid. Hereby, according to the medical database search, we report that the first renal cyst infection caused by B. abortus was successfully treated with triple antibiotic therapy.

We report a case of acute aortic dissection leading to compression of the left renal vein (LRV), thereby resulting in the nutcracker phenomenon. A 49-year-old previously healthy woman presented with intermittent gross hematuria and mild left flank pain of five days' duration. Laboratory examinations were within normal limits, except for the elevated C-reactive protein. Cystoscopy revealed bleeding from the left ureteral orifice. Contrast-enhanced computed tomography demonstrated acute Type B aortic dissection and compression of LRV between the enlarged aorta and superior mesenteric artery with an associated dilatation of the left gonadal vein as a collateral circulation.

Introduction Severe nephrotic syndrome is associated with increased morbidity and mortality. Renal artery embolization (RAE) has been used in a number of renal diseases such as renal tumors, arteriovenous fistulas etc. However, data regarding benefits of RAE in patients with symptomatic severe proteinuria is limited. We decided to evaluate role of RAE in the setting of severe symptomatic nephrotic syndrome. Methods Eight patients who had undergone transcatheter renal artery embolization with polyvinyl alcohol (PVA) were included. Clinico-demographic characteristics as well as baseline laboratory data including level of proteinuria, serum albumin, C-reactive protein and LDL cholesterol levels were recorded for each patient. After RAE, outpatient clinic control laboratory values were also assessed. Findings All patients except one underwent bilateral RAE (four simultaneous or three sequential). Two patients experienced postembolization syndrome characterized by flank pain, fever, and leukocytosis, which was self-limited and responded to analgesics in all patients. There was no technical complications associated with RAE procedure. All patients became anuric except one. Serum albumin levels increased and serum LDL-cholesterol levels decreased considerably in treated patients. Discussion Renal artery embolization with the purpose of amelioration in nephrotic syndrome complications was effective and free of major technical complications in our patients.

BACKGROUND This is a case report of a male patient who presented with a history of right flank pain based on renal infarction. Initially the symptoms were misdiagnosed as acute pyelonephritis. CASE REPORT A 47-year-old male with a history of familial hypercholesterolemia and cerebral infarction presented at the Emergency Department with a 3-day history of acute right-sided flank pain. Physical examination revealed hypertension, subfebrile temperature, and costovertebral angle tenderness. Blood tests were unremarkable except for renal impairment, a high C-reactive protein level of 215 mg/L (normal <8 mg/dL) and an elevated lactate dehydrogenase (LDH) of 1289 U/L (normal <248 U/L). Renal ultrasonography was normal. He was admitted with a presumed diagnosis of acute pyelonephritis and treated accordingly. However, 2 days later, we rejected this diagnosis as the urine culture was sterile. Based on the acute onset of symptoms and the initial high LDH, renal infarction was suspected. A computed tomography scan confirmed right-sided partial renal and splenic infarctions likely due to spreading emboli from atherosclerosis of the descending aorta. CONCLUSIONS Acute renal infarction is often missed or delayed as a diagnosis because patients often present with flank pain that can resemble more frequently encountered conditions such as pyelonephritis and nephrolithiasis. Renal infarction should be considered in cases with acute flank pain accompanied by (low-grade) fever, high LDH level, increased C-reactive protein level, hypertension, and renal impairment, especially in those patients with an increased risk of thromboembolism.
