Randomized Open Label Study Evaluating the Coverage by Teleconsultation Versus Standard Follow-up of Renal Transplant Patients According to a Risk Score of Early Graft Failure (KTFS)

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)
