Patient 6 was admitted with acute respiratory failure, lung infiltrates, and acute renal failure (plasma creatinine 2.8% mg),
microhematuria, and leukocyturia.
En fases iniciales de la enfermedad ocurre una
microhematuria que puede ser imperceptible (estadio subclinico); y progresivamente la orina se torna oscura, pasando por emisiones enrojecidas intermitentes o macrohematuria (estadio clinico) (Jubb et al., 1991).
Although urinalysis and microscopic exam are accurate for detecting
microhematuria, both lack sensitivity and specificity for bladder cancer.
She was stone-free, but had persistent
microhematuria.
In Coyhaique (Chile), Tapia (10) saw petechiac in 38% (9/24), epistaxis in three pediatric patients and
microhematuria in 16 patients (66.6%).
Their accuracy for the detection of
microhematuria is high, but their sensitivity and specificity for bladder cancer are low.
Screening for bladder cancer is not part of health care recommendations in any country but urinalysis and dipstick testing for
microhematuria is routinely performed as part of a regular check-up.
This flulike disease accompanied by
microhematuria was recorded in southern Moravia.
Two-thirds of the urines demonstrated
microhematuria and one-fifth showed gross hematuria.
The patient had blood in his stool, and urinalysis showed
microhematuria and a small amount of protein.
In addition,
microhematuria, detected during urinalysis performed as part of a regular medical checkup or for the diagnosis of another medical condition, may be the first sign of bladder cancer.
The
microhematuria assay has a clinical sensitivity of 99% and a specificity of 96%.
