The protocol biopsy strategy has been criticized because of risks and marginal utility. We tested the risk. We performed 1171 protocol biopsies in 508 patients at 6, 12 and 26 weeks after renal transplantation, as well as 499 biopsies as indicated in 429 transplant patients.

We tested whether a renal arterial resistance index of less than 80 was predictive of long-term allograft survival.
Methods: The renal segmental arterial resistance index (the percentage reduction of the end-diastolic flow as compared with the systolic flow) was measured by Doppler ultrasonography in 601 patients at least three months after transplantation between August 1997 and November 1998.
