Doppler technologies in combined diagnosis of acute pyelonephritis

: We studied diagnostic potentialities of conventional clinical, device, x-ray and ultrasonic methods including current Doppler technology in differentiation of serous and purulent stages of acute pyelonephritis (AP) in 50 patients (mean age 25.5 +/- 5.5 years). Energetic dopplerangiography (EDA) showed the highest diagnostic significance. EDA was highly informative in renal carbuncle and total purulent destruction of the kidney and low informative in serous and apostematous AP, renal abscess. Conventional ultrasonic, x-ray, clinical and device investigations as well as impulse dopplerography and color Doppler mapping of blood flow are of secondary importance in AP.
