KEY FACTS

  • Terminology

    • Imaging

      • Top Differential Diagnoses

        TERMINOLOGY

        • Abbreviations

          • Perigraft fluid collections (PFC)
        • Definitions

          • Not uncommon in early postoperative period and usually asymptomatic
          • PFC include hematomas, seromas, urinomas, lymphoceles, and abscesses
          • Depending on size and location, PFC may cause mass effect on allograft resulting in hydronephrosis or graft dysfunction
          • Hematomas/seromas: Normal sequela of surgery often small, seen immediately after transplantation
          • Lymphoceles, most common PFC, occur in 5-15% patients, usually after 4 weeks
            • Frequently cause hydronephrosis due to extrinsic ureteral compression
          • Urinomas occur in 2-5% of patients secondary to anastomotic leak or ureteric ischemia within first 2 weeks
          • Abscesses occur later in postoperative period with clinical evidence of infection
            • Bacterial or fungal infection not uncommon in renal transplant patients due to immunosuppression
