Report format or template- Doppler ultrasound atrophic kidney


Ultrasound and color Doppler report template/ format of atrophic left kidney
 
1)KIDNEYS:
RT.--    8.4 x 4.0 cms ;
LT.--    4.9 x 3.2 cms  ;
Left kidney appears normal. No pelvicalyceal dilation is seen.
Rt. Kidney appears small and atrophic with very poor vascularity.
3 to 4 small caluli of 2 to 5 mm. are seen in right kidney.
Renal parenchymal thickness: Lt.-   1.9 cms          Rt.—1.0 cms
Perirenal spaces are normal.

2) COLOR DOPPLER IMAGING:
A) Renal parenchymal flow:
(Intrarenal vasculature)
Lt: normal.
Rt: very poor vasularity seen in whole of right kidney.
B) Segmental arterial flow:
1) Any damping of spectral tracing: marked dampening of flow seen in right kidney.
2) RI (normal is < 0.7): Lt: 0.7
                                      Rt: 0.4
C) Renal arterial flow:
1) RI (RESISTANCE INDEX) –renal arteries
Lt: 0.6
Rt: Rt. renal artery is not visualized clearly.
2) PEAK SYSTOLIC VELOCITY (PSV) (renal artery): (NORMAL = 74-127 cms./sec).
LT: 38 to 40
RT: not visualized.
3) Width= Lt. renal artery-- 0.6 cms. (near hilum).
              Right renal artery-- ??. (near hilum)
4) RAR (RENAL ART PSV/AORTIC PSV. Normal RAR is <3.3):
Lt--
Rt--



5) Spectral waveform pattern of renal arteries:
Lt-- normal.
Rt-- ??


6) Any evidence of AV fistulae or malformation:
Nil.

URINARY BLADDER:
Distension—normal
Any trabeculation: no evidence of trabeculation seen.
Calculus: no calculus is present
Diverticulum: no diverticulum is seen.

Liver shows mild fatty change.
Pancreas, gall bladder and spleen appear normal.

OPINION:

COLOR DOPPLER scan suggests
  • Left kidney/ left renal artery appear normal. No pelvicalyceal dilation is seen.
  • Rt. Kidney appears small and atrophic with very poor vascularity.
  • 3 to 4 small caluli of 2 to 5 mm. are seen in right kidney.
  • Very poor vasularity seen in whole of right kidney.
  • Marked dampening of flow seen in right kidney
  • Rt. renal artery is not visualized clearly.

SUGGEST: clinical correlation and follow up.
CT or MR angiography of the renal arteries should be done to confirm these findings.
