Abstract Background A history of preoperative obstructive pyelonephritis has been reported as a risk factor for febrile urinary tract infection (fUTI) after ureteroscopic lithotripsy (URSL). But there is no clear evidence factors developing fUTI including the optimal timing URSL treatment. Methods Of 1361 patients, who underwent at our hospital from January 2011 to December 2017, 239 patients h...

The Clinical Case of the Month is a regular educational feature presented by the Louisiana State University Department of Medicine. Medical students, residents, postdoctoral fellows, and faculty collaborate in the preparation of these discussions. After reading this article, physicians should be better able to identify and understand the pathophysiology, microbiology, epidemiology, clinical pre...

In the period between October 1st and November 30th, 2006, we investigated a total of 3188 episodes of UTI (802 among males; 2386 among females) recorded in 108 family medicine offices in 20 cities in Croatia. The most common UTIs in women were acute uncomplicated cystitis (62%), complicated UTIs - cystitis and pyelonephritis (14%), urethritis (9%), acute uncomplicated pyelonephritis (6%), recu...

Recently, water diuresis has been shown to promote chronic Escherichia coli bacteriuria following the injection of bacteria into the bladder lumen of rats with normal urinary systems(l). However, maintenance of bacteriuria for periods up to 56 days has not resulted in renal lesions(l,2). Similar effects of water diuresis on bacteriuria have been observed in mice. In this species, however, sever...

PURPOSE A critical early step in the establishment of Escherichia coli pyelonephritis is bacterial attachment via the tip protein of P fimbriae. This adhesin, PapG, binds to glycolipid receptors present on vaginal and kidney epithelial surfaces. In this study we investigated the efficacy of vaccination with purified PapDG protein complex in preventing pyelonephritis caused by E. coli. MATERIA...

The objective of this case report is to describe the first case of renal actinomycosis caused by Actinomyces meyeri presenting as severe emphysematous pyelonephritis and complicated by septic shock and multi-organ failure. Emphysematous pyelonephritis is a potentially life-threatening infection mostly described in diabetic patients and predominantly caused by uropathogenic bacteria. Actinomycos...

The article represents the authors’ own observation of patient with xanthogranulomatous pyelonephritis (XPN). Xanthogranulomatous pyelonephritisis a rare form ofchronic bacterial calculous pyelonephritis. Factors predisposingto thedevelopmentof include following: impairment theurinary flowalong theurinarytract, type II diabetes mellitus, and chronic inflammation kidney. XPN is an uncommon cause...

Hidden renal mass is not evident during severe inflammation such as acute pyelonephritis, pyonephrosis, or renal abscess. Deceptive inflammatory presentations that can occur in aggressive synchronous renal malignancies can significantly delay the diagnosis of cancer. Herein, we report a case of acute pyelonephritis involving overlooked renal cell carcinoma.

Emphysematous pyelonephritis, a necrotizing infection of the renal parenchyma caused by gas-producing organism, is a rare but life-threatening condition. The initial presentation could be non-specific. We report a case of emphysematous pyelonephritis in a patient presenting with poorly controlled diabetes mellitus and severe sepsis. Its pathogenesis and management are briefly discussed. (Hong K...

In recent years more attention has been paid to the diagnosis of pyelonephritis, and this has made accurate estimation of pyuria more necessary. Houghton and Pears (1957), Hutt, Chalmers, MacDonald, and de Wardener (1961), and Little (1962) have all reported their experience in measuring the rate ofurinary white cell excretion. Their figures are very largely derived from adults; the present rep...
