Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Written informed consent
  • Age > 18 years
  • Patients wishing to close the fistula and planned for surgical fistula closure
  • eGFR CKD EPI ≥ 45 ml/min/1.73m2 at one year post transplantation
  • Stable eGFR within the past 6 months
  • Controlled blood pressure

Exclusion criteria

  • Kidney Transplantation < 12 months before fistula closure
  • Proteinuria > 500mg/d
  • Presence of donor specific antibodies
  • Rejection within the past 6 months
  • BK virus replication within the past 3 months
  • Cardiac pacemaker, which is not compatible with MRI
  • Claustrophobia

Treatment and study plan

Echocardiography and MRI

Diagnostic Test

Echocardiography and renal MRI before and after fistula closure

Primary outcomes

  1. Assessment of changes in renal hemodynamics by multiparametric MRI after closure of AVF access

    Time frame: evaluation of short term changes within 2 weeks after fistula closure and longterm changes 6 months after fistula closure

    Assessing changes in renal perfusion

  2. Assessment of changes in renal hemodynamics by multiparametric MRI after closure of AVF access

    Time frame: evaluation of short term changes within 2 weeks after fistula closure and longterm changes 6 months after fistula closure

    Assessing changes in renal oxygenation

Secondary outcomes

  1. Correlation between AVF access flow and changes as assessed during pneumatic fistula compression with changes in renal hemodynamics after fistula closure

    Time frame: evaluation of short term changes within 2 weeks after fistula closure and longterm changes 6 months after fistula closure

    Correlation between AVF access flow and changes as assessed during pneumatic fistula compression with changes in renal hemodynamics after fistula closure
