Key result
Renal Doppler detects nutcracker syndrome in ~33% of children with isolated hematuria versus none in controls.
Why the study?
The prevalence of nutcracker syndrome in children with isolated hematuria and the impact of renal Doppler ultrasound on its detection were not well established.

Does renal Doppler ultrasound effectively detect nutcracker syndrome in children with isolated hematuria?
Absolute Event Rate: 33.3% vs 0%
p-value: p=<0.0001
Renal Doppler ultrasound is an effective screening tool that reveals a relatively high prevalence of nutcracker syndrome in children with isolated hematuria.
Shin et al. (2006) conducted a cross-sectional in Isolated hematuria (n=248). Renal Doppler ultrasound vs. Healthy normal children was evaluated on Detection of nutcracker syndrome (PV2/PV1 ratio > 4.1) (p=<0.0001). Routine renal Doppler ultrasound detected nutcracker syndrome in 33.3% of children with isolated hematuria compared to 0% of healthy controls, using a peak velocity ratio cut-off of 4.1.
