Key result
Sympathetic activation via cold pressor and handgrip tests significantly increased renal resistive index (P<.001), while intravenous fluid load significantly decreased it (P<.001).
Why the study?
Can pulsed wave Doppler analysis accurately evaluate changes in renal vascular resistance induced by aging and vasomotor stimuli in healthy subjects?
Observational
Can pulsed wave Doppler analysis accurately evaluate changes in renal vascular resistance induced by aging and vasomotor stimuli in healthy subjects?
p-value: p=<.001
Pulsed wave Doppler analysis is an accurate method for the indirect evaluation of changes in renal vascular resistance induced by aging and common vasomotor stimuli.

Doppler RRI reliably tracks age- and stimulus-induced renal resistance shifts; leaves open its clinical role in hypertension pending prospective validation.
Maria Boddi (1996) conducted an observational in Healthy. Vasomotor stimuli (cold pressor test, handgrip test, fluid load) vs. Baseline was evaluated on Renal resistive index (RRI) (p=<.001). Sympathetic activation via cold pressor and handgrip tests significantly increased renal resistive index (P<.001), while intravenous fluid load significantly decreased it (P<.001).
