title: Image-directed color Doppler ultrasonography of kidney in systemic lupus nephritis.
abstract: We evaluated intrarenal arterial waveforms with image-directed color Doppler ultrasonography in 21 patients with systemic lupus erythematosus (SLE). The systolic-diastolic ratio, resistive index, and pulsatility index were compared with serum creatinine levels, creatinine clearance, and quantitation of urinary protein excretion, as well as with histopathologic scores of specimens obtained from 9 patients who underwent renal biopsy. Doppler parameters were in the normal ranges in all patients, without showing significant correlation with any of the histopathologic scores or laboratory parameters except creatinine levels. We conclude that image-directed color Doppler ultrasonography is of no practical value in the evaluation of lupus nephritis during the early stages of the disease.
