59 year old male patient status post DDRT with decreased urine output, baseline ultrasound. RENAL TRANSPLANT: LOCATION: Left iliac fossa.PERITRANSPLANT TISSUES: No perinephric fluid collection is identified.KIDNEY: The transplant kidney measures 8 cm in length.COLLECTING SYSTEM/URETER: There is mild pelvocaliectasis.URINARY BLADDER: The bladder is decompressed with a Foley catheter.VASCULAR DOPPLER DATA: Color and spectral Doppler were performed on inflow and outflow vessels The transplant renal vein is patent.There is decreased diastolic flow with increased RI of the mid/hilum transplant renal artery and segmental arteries. Velocities and RI are as follows:Transplant renal artery anastomosis: 47 cm/s with RI of 0.44Transplant renal artery mid: 72 cm/s with RI of 0.96Transplant renal artery hilum: 50 cm/s with RI of 0.90RI range for segmental arteries: 0.85 to 1.0RI range for arcuate arteries: 0.50 to 0.69OTHER: No significant abnormality noted
1. Increased intrarenal resistive indices which can be seen with parenchymal dysfunction.2. Patent transplant renal vein.3. Mild pelvocaliectasis.
