Doppler Flow Parameters
RIGHT KIDNEY
| Vessel | PSV (cm/s) | EDV (cm/s) | RI | AT (Acceleration Time) |
|---|---|---|---|---|
| Main Renal A | 47 | 13 | 0.65 | 133 ms |
| Segmental A | 44 | 13.6 | 0.69 | 122 ms |
| Inter Lobar A | 36 | 10 | 0.65 | 164 ms |
| Arcuate A | 21 | 5.5 | 0.62 | - |
LEFT KIDNEY
| Vessel | PSV (cm/s) | EDV (cm/s) | RI | AT (Acceleration Time) |
|---|---|---|---|---|
| Main Renal A | 34 | 12 | 0.7 | 180 ms |
| Segmental A | 45 | 15 | 0.66 | 178 ms |
| Inter Lobar A | 29 | 9 | 0.65 | 130 ms |
| Arcuate A | - | - | - | - |
Aorta: PSV 44 cm/s, EDV 8.6 cm/s
Renal Aortic Ratio: < 3.5
Impression (Radiologist's Notes)
- No evidence of Renal Artery Stenosis (RAS) bilaterally
- Mild increased RI at both renal vessels - suggestive of early/early changes of Intra-Renal Parenchymal Disease (IRPD)
- Signed by Radiologist
Key Clinical Takeaways
- Kidney sizes are normal (right 10.8 cm, left 10.4 cm) - no atrophy or enlargement.
- Resistance Indices (RI) are mildly elevated (normal < 0.70). The left main renal artery RI is at 0.70, which is at the upper limit, suggesting early parenchymal disease.
- Acceleration Times (AT) on the left side are prolonged (180 ms, 178 ms; normal < 70-100 ms in main renal artery), which may indicate downstream resistance rather than proximal stenosis.
- No RAS - the renal-aortic ratio is < 3.5 (normal), ruling out significant renal artery stenosis.
- Mild increased cortical echogenicity - consistent with early chronic kidney disease (CKD) or medical renal disease.
This report is consistent with early Intra-Renal Parenchymal Disease, likely representing an early stage of chronic kidney disease. Follow-up with nephrology and serum creatinine/GFR assessment is advisable.
