CLINICAL STUDY ON FUNCTION REVERSIBILITY OF CADAVERIC RENAL ALLOGRAFTS

II. Prediction of Function Reversibility with Monitoring of Hemodynamics of the Grafts by Ultrasound Doppler Technique

Abstract

Measurements of arterial blood flow of the transplanted kidneys by directional ultrasound Doppler technique were performed in 20 cadaveric renal transplant recipients with the purpose of predicting the reversibility of cadaveric renal allograft function and diagnosing acute rejection during posttransplant anuric phase.
Reversibility of the graft function was predictable by blood flow pattern analysis even within a week after transplantation. Serial measurements of the blood flow made it more predictable. Of blood flow parameters, acceleration time had a good correlation with the reversibility of the graft function.
Acute rejection episodes in posttransplant anuric patients were able to be diagnosed by this method, demonstrating mainly diminished diastolic blood flow in Doppler flow pattern.
This method appears to be a useful technique for management of cadaveric renal transplant recipients, especially those with posttransplant anuria.
