title: Duplex Doppler evaluation of acute renal obstruction.
abstract: Patients with possible acute renal obstruction often undergo numerous types of radiological examinations. Renal Doppler ultrasound is a quick and noninvasive way to assess for physiological and hemodynamic changes that accompany acute obstruction. The renal Doppler study may provide unique data not available from conventional sonography. Most, but not all, clinical and laboratory studies regarding Doppler of acute renal obstruction have reported encouraging results. As limitations to the Doppler examination in this clinical setting are delineated, a proper role for renal Doppler will continue to emerge.
