Abstract
In a retrospective study we sought to dissect the factors associated with an increased occurrence of clinically significant perinephric fluid collections and lymphoceles among sirolimus-treated renal transplant recipients. We compared the incidence, predisposing factors, and consequences of these fluid collections among patients treated with sirolimus-cyclosporine (CsA)-prednisone (Pred) (n=354, group I) versus CsA-Pred with or without azathioprine (n=136, group II). More group I patients (135/354; 38.1%) displayed perinephric fluid collections (denoted as group III) then group II patients (24/136; 17.6%) (denoted as group IV) (P Conclusions. Addition of sirolimus to a CsA-Pred regimen resulted in both a higher incidence and a requirement for more aggressive treatment of perinephric fluid collections and lymphoceles.
