Differential diagnosis

Acute uncomplicated pyelonephritis Acute pyelonephritis is a urinary tract infection that has progressed from the lower urinary tract to the upper urinary tract. Most episodes of acute pyelonephritis are uncomplicated but hospitalization may be required. Acute uncomplicated pyelonephritis typically occurs in healthy, young women. http://www.utdonline.com/home/content/topic.do?topicKey=uti_infe/6922

Urinary Tract Infection Exists when pathogenic microorganisms are detected in the urine, urethra, bladder, kidney, or prostate. Access is through ascent of bacteria from the urethra to the kidney. Commonly caused by gram-negative bacilli.

Urinary Tract Infection Conditions affecting Pathogenesis Gender and Sexual activity Pregnancy Obstruction Neurogenic Bladder dysfunction Vesicoureteral Reflux Bacterial Virulence factors Genetic Factors Gender and Sexual Activity- females are more prone due to the proximity of the anus to the urethra, the short length of the urethra, and its termination beneath the labia. Sexual intercourse introduces bacteria into the bladder which may cause cystitis. Pregnancy- during pregnancy, there is reduced ureteral tone, decreased ureteral peristalsis, and temporary incompetence of the vesicoureteral valves. Obstruction- any impedement to the flow of urine results in hydornephrosis and this greatly increases frequency of UTI. Neurogenic bladder dysfunction- infection may be initiated by the use of catheters for bladder drainage and is favored by the prolonged stasis of urine in the bladder. VR reflux- allows for the reflux of bacteria and thus upper tract infection.

Genitourinary Tuberculosis Genitourinary tuberculosis (GUTB) may involve the kidneys, ureter, bladder, or genital organs The infection almost always affects the kidneys during the primary exposure to infection but does not present clinically. The spread to the kidneys from the lungs, bone, or a GI tract focus usually is hematogenous.

Pulmonary tuberculosis Tuberculosis is an infectious disease caused by mycobacteria, usually Mycobacterium tuberculosis transmitted by airborne droplet nuclei, which may contain fewer than 10 bacilli When inhaled, droplet nuclei are deposited within the terminal airspaces of the lung.
