Stage 1: randomization. Two arms: teleconsultation and standard consultation

Stage 2: calculation of Kidney Transplant Failure Score which will determine 4 sub-groups: teleconsultation high risk, teleconsultation low risk, standard consultation high risk and standard consultation low risk.

Stage 3: follow-up (2 years) according to the group:

• Standard consultation low risk: consultation every 2 months during one year and then every 3 months during one year
• Standard consultation high risk: consultation every 6 weeks during one year and then every 2 months during one year
• Teleconsultation low risk: same follow-up as "standard consultation low risk" group but all the consultations are teleconsultations
• Teleconsultation high risk: same follow-up as "standard consultation high risk" group but the follow-up will be intensified by the addition of an intermediate teleconsultation (between 2 consultations)

The main objective of this study is to optimize the coverage of renal transplant patients thanks to a personalized follow-up based on a risk score of early graft failure (KTFS, Kidney Transplant Failure Score), associated with teleconsultations.
