Xanthogranulomatous pyelonephritis is a rare disease characterised by the replacement of normal renal parenchyma by foamy macrophages. The only treatment for this type of pyelonephritis is of a surgical nature with partial or total nephrectomy. The occurrence of xanthogranulomatous pyelonephritis during pregnancy is a rare event (with only 6 cases described in the literature). We report a case ...

This study was carried out to elucidate by serological examination the etiological significance of mycoplasmas isolated from the upper urinary tract of patients with pyelonephritis. The occurrence of antibodies in patients with acute pyelonephritis, chronic pyelonephritis with or without exacerbation, or noninfectious urinary tract disease was compared by the indirect hemagglutination method. A...

Diagnosing acute pyelonephritis relies on the combination of historical, physical, and laboratory findings. Costovertebral angle tenderness is important, although its accuracy is unknown. Point-of-care ultrasound-guided palpation (sonopalpation) may aid clinicians in localizing pain to discrete anatomic structures in cases of suspected acute pyelonephritis lacking classic features. We describe ...

Despite the inherent differences in the various bacterial species responsible for human pyelonephritis, little consideration has been given to differences in the characteristics of the renal disease resulting from infection by each species. While it is possible that pyelonephritis is a single disease entity that develops in an identical fashion regardless of the type of bacteria, scattered clin...

INTRODUCTION The aim of this study was to evaluate the possibility of differentiating xanthogranulomatous pyelonephritis (XGPN) preoperatively from chronic pyelonephritis on the basis of demographic data, clinical parameters, and biochemical, microbiological, and radiological workups. MATERIALS AND METHODS Between 1995 and 2005, a total of 239 patients were diagnosed to have pyelonephritis at...

Background: Pyelonephritis is a renal inflammatory condition diagnosed with patient’s history, physical examination and imaging studies. Although laboratory finding, clinical sign symptoms are considered for the diagnosis treatment. Aim: To compare sonographic findings of pyelonephritis urine complete Methodology: A Cross sectional analytical study was conduct at Gilani Ultrasound Center, Feroz...

It is increasingly recognized that many problems concerning the aetiology, recognition and natural history of urinary tract infections are still unresolved, and this is particularly true of such infections in infancy. There is, for example, no general agreement about their incidence in the first months of life: Stansfeld (1954) has pointed out that pyelonephritis occurs more frequently in the f...

Studies of the pathogenesis of experimental pyelonephritis have been limited because of lack of a suitable model. Although several types of renal and extra-renal manipulations have been shown to predispose the kidneys of experimental animals to pyelonephritis, the investigator is frequently unable to distinguish between the effects of the predisposing injury and the induced infection. The few m...

INTRODUCTION Tumor necrosis factor-alpha (TNF-alpha) is an important mediator of the inflammatory response in serious bacterial infections. The aim of this study was to evaluate the potential of urinary TNF-alpha for diagnosis of acute pyelonephritis in children. MATERIALS AND METHODS This study was conducted from March 2006 to December 2007 on children with confirmed diagnosis of acute pyelo...

Objective: To calculate the frequencies of acute pyelonephritis and renal scarring in patients under the age of two, with first episode of urinary tract infection in a Brazilian university hospital, comparing with data reported in the international literature. Materials and Methods: Scintigraphic reports of children less than two years old submitted to Tc-DMSA renal scintigraphy in a university...
