UNLABELLED: The study of renovascular resistances by color Doppler ultrasound has become a useful diagnostic resource for nephrologists. In recent nephrological literature, many papers deal with the correlations between resistive index, anatomo-pathological patterns and renal function. AIMS: In our study, we have tried to discover if resistive index represents a prognostic index of progressive renal failure. MATERIAL AND METHODS: To this purpose we compared renal resistive index and blood creatinine obtained from 28 nephropathic patients at their first control, with blood creatinine values after a 3-year follow-up period. Using a linear regression test, we found a strong correlation between the initial value of resistive index and the value of creatinine variation (p = 0.006). RESULTS: All of the patients with normal resistive index at the beginning maintained a stable renal function. Conversely, the patients with high resistive index at their first control showed a progressive renal failure. CONCLUSION: Our study shows the reliability of resistive index in the prognostic evaluation of renal outcome.
