was defined as at least 105 colony-forming units per ml of one or two microorganisms in urine culture, and pyuria was defined as any number of white blood cells on urinalysis.
* Recurrent UTI is an infection that follows resolution of bacteriuria
and symptoms of a prior UTI, and the term applies when such an infection occurs within 6 months of the last UTI or when 3 or more UTIs occur within a year.
Accuracy of diagnostic tests to detect asymptomatic bacteriuria
In the guidelines published by the Infectious Diseases Society of America, it is clear that there is no evidence of benefit in treating asymptomatic bacteriuria
. Asymptomatic bacteriuria
(AB) is present in approximately 70% of patients with spinal cord injury and neurogenic bladder who perform intermittent bladder catheterization (11) due to functional abnormalities, urinary stasis, and the bladder emptying technique.
Uma vez que essas infeccoes podem causar serios danos renais, caso permanecam sem tratamento, muitos medicos consideram prudente solicitar testes para deteccao de bacteriuria
em individuos com alto risco.
Nitrites on a urine disptick in the absence of symptoms or urine leucocytes may suggest asymptomatic bacteriuria
or bacterial contamination rather than urinary tract infection (cystitis or pyelitis).
The variables measured using urinalysis reagent strips included pH, protein, glucose, bilirubin, specific gravity, blood, ketones, urobilinogen, LE (as an indicator of pyuria), and NT (as an indicator of bacteriuria
Spinal cord injury patients with neurogenic bladder often have bacteriuria
without signs and symptoms of infection due to catheterization.
Conclusion: The incidence of PUBS in the elderly population is associated with asymptomatic bacteriuria
, urine pH, and gender but not renal function, type of feeding, or type of Foley catheter used.
