Abstract

The correlation of B mode and Doppler sonographic parameters and diagnoses established by histological examination of graft biopsies, nephrectomies and clinical data are discussed. 48 histological samples from 36 patients were reevaluated. The maximum interval between sonography and histology was 36 hours. The Banff classification criteria were used during histological examinations. Doppler examination evaluation was based on the resistance index (RI). Reproducibility was controlled by means of intra- and interobserver variability in 10 patients. RI values higher than 75% were regarded as abnormal. On the basis of these observations and the literature data specific sonographic features can be detected in renal artery occlusion and renal vein thrombosis. In pyelonephritis, dilatation of the collecting system was frequent. No morphological changes were detected in cyclosporin-A nephrotoxicity and the Doppler signs were not characteristic for this disease. No differentiation was found between acute rejection and acute tubular necrosis. The noninvasive duplex sonographic examinations can provide very important information regarding the flow situation of a transplanted kidney. In some cases a definitive diagnosis can be achieved, but in other cases biopsy is the method of choice.
