ABSTRACT
Patients with infections comprise the greatest percentage of any group with fever of unknown origin (FUO). J. Hamburger and colleagues stress the fact that there exists an unexplained fever, well tolerated, moderate or high, sometimes with daily spikes of 3 to 4 h duration, always with the same patient. Fever of FUO as published in 1961 by R. G. Petersdorf and P. B. Beeson and defined by C. A. Dinarello and W. C. Wolf in 1979 is extremely rare in urology. Glomerulonephritis is not in the domain of the urologist, unless the patient consults for hematuria or at the end stage when renal transplantation is contemplated. Acute pyelonephritis is the pathological process following bacterial infection in the renal parenchyma and pelvicalyceal system. The appearance of a relatively normal renal architecture at sonography, and the presence of nonvisualization at urography, should raise the suspicion of renal tuberculosis. Infectious diseases remain a major cause of morbidity and mortality in renal transplant recipients.
