[Intrarenal color Doppler ultrasound for exclusion of XXXX in cases of @entity8 . Analysis of the Doppler spectrum and tardus parvus phenomenon].

@entity1 @entity8 @entity101 @entity2791 @entity850
PURPOSE: To diagnose possible @entity2791 especially in case of @entity8 by intrarenal colour-coded Duplex sonography. METHODS: In 50 @entity101 @entity1 lobar and interlobar arteries were looked for at 3 different levels. Analysis included the determination of the early systolic acceleration time and the assessment of the Doppler waveform, especially the "tardus-parvus" phenomenon. Intraarterial angiography was performed in all @entity1 the next day. RESULTS: In 48/50 @entity1 the sonographic investigations were sufficiently evaluable. Angiography showed haemodynamically relevant @entity850 in 13 @entity1 , in 4 @entity1 bilaterally. In 21 @entity1 (42%) @entity8 were found. Sensitivity and specificity in the diagnosis of @entity2791 was 77% respectively 46% (threshold value > or = 0.120 s). In 10/17 angiographically verified haemodynamically relevant @entity2791 a change of the Doppler waveform was noted; sensitivity in the diagnosis of @entity2791 was 69%, specificity 90%. CONCLUSION: Intrarenal colour-coded Duplex sonography cannot be recommended as a screening tool for @entity2791 .
