Lymphatic complications in renal transplantation

Lymphocele and lymphatic fistulae are relatively benign complications in renal transplantation. The incidence in our series of 248 renal transplants was 8%. The origin and pathogenesis of lymph collection and augmented lymph flow are discussed. The main importance of this complication lies in its differential diagnosis with urinary fistula and acute rejection episode or deep phlebothrombosis with all its therapeutic implications. Important lymph accumulations should be drained. We prefer as initial treatment a percutaneous closed aspiration which most successfully solves the problem. In case this method should fail, one can choose between external or internal drainage. As in literature, we actually prefer an internal marsupialisation, but completed by an omentoplasty if the leakage originates from the kidney.
