Conditions

Long-term graft survival Surgery Graft survival

Interventions

Intervention: ultrasound-guided protocol biopsy 3 and/or 12 months after kidney transplantation. Based on the histology, appropriate treatment: 1. Steroid intravenous (i.v.) bolus 2. CNI dose reducti
treated based on clinical symptoms (if any occur). 10 years follow-up is planned, analysing data annually.
