Influence of Renal Impairment on the Success of Reconstruction Using Microvascular Grafts-A Retrospective Study of 251 Free Flaps.

Nevertheless, increased renal parameters are associated with increased incidence of serious complications. Therefore, these should be considered in the indication and preoperative planning.
