title: Evaluation of Kidney Allograft in the Early Posttransplant Period Using Ultrasonography.
abstract: OBJECTIVE
  The aim of this study was to evaluate the kidney allograft after transplant to assess restoration of blood flow, the time required to functionally recovery after surgery, and the ability to differentiate normal from pathologic grafts using color Doppler ultrasonography in the early posttransplant period.
  
  
  METHODS
  Sixteen kidney recipients underwent renal color Doppler ultrasonography examinations 1, 2, 3, 7, 15, and 30 days after transplant. We evaluated the clinical and biochemical test results of recipients and the functioning allografts and evaluated the acute pathology. Results of resistive index in color Doppler ultrasonography were compared with blood test results.
  
  
  RESULTS
  During the early postoperative period after kidney transplant, the average size of the kidney was 10.7 × 5.1 cm, with parenchyma at 1.7 cm. The structure of the parenchyma was nonhomogeneous in 14 patients and homogeneous in 2 patients. The medullary pyramid layer was prominent in 6 patients, moderately prominent in 7 patients, and not prominent in 3 patients. The pyelocaliceal system was condensed in 1 patient. Hematoma in the perinephrium was found in 5 patients, and free fluid was found in 5 patients. Satisfactory vascularization of allografts occurred in 14 patients, with resistive index sensitivity of 93% and specificity of 83%.
  
  
  CONCLUSIONS
  Color Doppler ultrasonography and resistive index results were useful in evaluating kidney allografts during the early postoperative period and in confirming their condition despite excessive blood parameter values.
