Pyelonephritis affects about 1 to 2 per 1,000 women each year and just under 0.5 per 1,000 males. [ 5 ] [ 7 ] Young adult females are most often affected, followed by the very young and old. [ 2 ] With treatment, outcomes are generally good in young adults.
About 150 million people develop a urinary tract infection in a given year. [2] They are more common in women than men, but similar between anatomies while carrying indwelling catheters. [7] [18] In women, they are the most common form of bacterial infection. [19]
When patients do not improve quickly with appropriate antibiotics, however, appropriate radiographic studies help diagnose pyonephrosis, emphysematous pyelonephritis, and renal and/or perirenal abscesses. [7]
Murphy's sign has a high sensitivity and negative predictive value, although the specificity is not high. [2] However, in the elderly the sensitivity is markedly lower; a negative Murphy's sign in an elderly person is not useful for ruling out cholecystitis if other tests and the clinical history suggest the diagnosis.
Lloyd's sign indicates the presence of renal calculus or pyelonephritis when pain is elicited by deep percussion in the back between the 12th rib and the spine. [1] It is closely related to costovertebral angle tenderness, as the area of percussion is the same. However, Lloyd's sign is specifically defined as positive costovertebral angle ...
This constellation of symptoms contrasts with the classical presentation of nephrotic syndrome (excessive proteinuria >3.5 g/day, low plasma albumin levels (hypoalbuminemia) <3 g/L, generalized edema, and hyperlipidemia). [8] [10] Signs and symptoms that are consistent with nephritic syndrome include: Hematuria (red blood cells in the urine) [11]

As for children with suspected pyelonephritis, a ten-day treatment regimen is recommended. In such cases, a third-generation cephalosporin, such as cefdinir, is suggested as an appropriate option. If second-line therapy is initiated in pediatric patients with suspected pyelonephritis, ciprofloxacin should be the preferred option among the four ...
