hydronephrosis occurs as a congenital or an acquired condition following obstruction of the urinary tract. in this study, a four month old male holstein calf with emaciation, growth retardation and a poor dry scruffy hair coat was examined because of remarkable distention of right abdomen. at necropsy, right kidney was hydronephrotic as a very big fluid-filled round pelvis with the presence of ...

BACKGROUND High rates of resistance to trimethoprim-sulfamethoxazole (TMP-SMX) among uropathogenic Escherichia coli are recognized, and concerns exist about emerging fluoroquinolone resistance. METHODS Adults presenting to 11 US emergency departments with (1) flank pain and/or costovertebral tenderness, (2) temperature >38 degrees C, and (3) a presumptive diagnosis of pyelonephritis were enro...

Hematogenous pyelonephritis was produced in rats utilizing multiple strains of Escherichia coli, a strain of Klebsiella pneumoniae, and a strain of Proteus mirabilis. Three patterns of hematogenous pyelonephritis occurred which represent an interrelationship between an immune response to the infecting bacteria and the development of obstructive uropathy as a consequence of infection. First, the...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016216025 DESCRIPTION A 48-year-old African-American woman was admitted to the hospital, because of weight loss and poor appetite for the past 3 months. The patient mentioned that she had nearly 30 lb of unintentional weight loss during this period. She had neither nausea, vomiting...

Uncomplicated pyelonephritis in man is almost always produced by a single species of bacteria, ordinarily a Gram-negative organism. Mixed infection of the urinary tract is usually associated with chronic obstruction or instrumentation. In animals the production of pyelonephritis results in an acute process, and in most models a single species of bacteria has been used as the infecting agent. It...

A study has been made of the effect of ureteral ligation on the susceptibility of the kidney to pyogenic infection. In most experiments a strain of E. coli was employed as the test organism, being injected intravenously in varying quantity either before or after ureteral ligation. A few experiments were also carried out with S. marcescens. Preliminary observations were made on the distribution ...

Emphysematous pyelonephritis (EPN) is a rare life threatening condition. It usually happens in diabetic patients. Its mortality is as high as 75% and urgent nephrectomy has been highly recommended.(1) However, recent advancements in imaging techniques and new stronger antibiotics can make medical treatment an acceptable alternative for radical surgery. We report a diabetic patient with EPN, who...

background tnf-α is one of the most potent cytokines in proinflammatory reactions. results one hundred and twenty children with acute pyelonephritis were evaluated. urinary tnf-α/cr was 0.0051 ± 0.00083 pg/g creatinine. the authors found out a significant difference in urinary tnf-α/cr between patients who have normal and abnormal levels of urine leukocytes, urine protein, urine culture, erythr...

Emphysematous pyelonephritis is a rare and life-threatening suppurative infection of renal parenchymal and perirenal tissues, characterized by spontaneous gas production. Although uncommon (76 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. coli, successfully...
