Resumo
Acute kidney injury resulting from toxic or ischemic insults and usually affect the
tubular portion of the nephron. Early detection allows the acute kidney injury
appropriate intervention may prevent or mitigate damage to the tubular cell and the
development of acute renal failure. Diagnosis requires a combination of techniques,
and be effective employment ultrasonography associated with laboratory tests.
Ultrasound allows assessment of morphology and renal echogenicity by taking on bidimensional
mode and renal hemodynamics through the assessment with pulsed
Doppler with the calculation of resistivity and pulsatility indices. The main ultrasound
changes of acute tubular injury are nefromegalia, cortical echogenicity increase or reduction, renal pelvis expansion, perirenal effusion, medular signal margin and
resistivity and pulsatility indices increase.
