Emphysematous pyelonephritis is a rapidly progressive acute necrotizing infection of the kidney parenchyma caused by gaseous anaerobic bacteria.(1-3) It is almost always seen in diabetic patients (more than 90% of cases) and is sometimes associated with urinary obstruction induced by renal stone, papillary necrosis, chronic infections, or kidney dysfunction.(1,3) It is bilateral only in 10% of ...

urinary tract infections are common in children. the available gold standard method for diagnosis, tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation. this study was performed to compare and assess the efficacy of power doppler ultrasound versus tc-99m dmsa scan for diagnosis of acute pyelonephritis. a quasi experimental study was conducted...

Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic pyelonephritis with progressive loss of renal function. Commonly, obstructing urinary calculi are seen. It is difficult to differentiate between XGPN and malignancy in many cases, and the diagnosis is usually only confirmed post-operatively upon histopathological examination of the specimen. Surgical treatment is often the main...

vesico-ureteral reflux (vur) is presented in approximately %1 of children and is associated with an increased risk of pyelonephritis and renal scarring. despite its prevalence and morbidity, many aspects of vur diagnosis and treatment are controversial. we objectively assessed the published data; the data base for many current diagnoses and treatment patterns of vur is limited. recent studies h...

Acute pyelonephritis is a potentially life-threatening infection of the upper urinary tract. Inflammatory response and the accompanying oxidative stress can contribute to kidney tissue damage, resulting in infection-induced intoxication that can become fatal in the absence of antibiotic therapy. Here, we show that pyelonephritis was associated with oxidative stress and renal cell death. Oxidati...

Xanthogranulomatous pyelonephritis is a severe, rare, form of chronic pyelonephritis characterized by the destruction of the renal parenchyma and replacement by granulomatous tissue.This disease has been called as the “great imitator” because clinical and radiological findings often mimics other inflammatory or neoplastic renal disorders leading to diagnostic challenge before histopathologic an...

OBJECTIVE: To determine whether the presence of abnormal results in DMSA renal scintigraphy indicates pyelonephritis. METHODS: We performed the washout test in 17 children with urinary tract infection, as a criterion standard, to locate the infection site. All the children underwent DMSA renal scintigraphy in the acute phase of the disease. The results were analyzed by the chi-square test or Fi...

The incidence of cystitis is much higher than that of pyelonephritis. Uncomplicated UTIs are episodios of acute cystitis or pyelonephritis when it occurs in a healthy premenopausal, non-pregnant woman with no known urological abnormalities (structural or functional) [1-5]. UTI that do not meet these criteria is considered complicated. This review is focused on management of acute uncomplciated ...

Uropathogenic Escherichia coli is the leading cause of urinary tract infection and hospital visits in North America. Cystitis and acute pyelonephritis, infection of the bladder and kidney, respectively, are the two most common syndromes encountered in patients with urinary tract infection. We sequenced and annotated 71,684 bases of a previously unidentified pathogenicity-associated island (PAI)...
