Renal transplant complications, role of resistive index on Color Doppler ultrasound

We evaluated 50 patients who had renal transplants and were sent for Doppler Ultrasound for complications, after the transplant procedure. Ages of the patients ranged from 20 to 65 years, 39 were male and 11 were female. In inclusions only first month post op patients were included and only those patients were considered who had some sort of complications on ultrasound at some stage of the follow up.Following complications were noticed: Diminished corticomedullary demarcations, increased echogenicity with raised R I (20 pt). Perinephric collections other than haematoma (13 pt). Perinephric haematoma (06 pt). Obstructed transplanted kidney ( 05 pt). Diminished arterial vascularity of the kidney (04 pt) Renal vein thrombosis (02 pt). RI was found to be raised in increased echogenicity, obstructed hydronephrotic kidney, diminished arterial supply and was disturbed in RVT.
