title: Did volume of lymphocele after kidney transplantation determine the choice of treatment modality?
abstract: BACKGROUND
  Lymphocele is a lymph collection that forms after surgery following injury to lymph nodes and vessels. The aim of the study was to perform a retrospective analysis of different treatment modalities of lymphocele in patients after kidney transplantation.
  
  
  METHODS
  A lymphocele located in renal graft area was observed in 25 of 386 transplanted patients (6.5%). Mean patient age was 45 (95% confidence interval [CI], 40 to 50) years. Mean observation time was 35 (95% CI, 27 to 43) months.
  
  
  RESULTS
  Mean time from transplantation to diagnosis of lymphocele was 29 days (range, 4 to 127). In 13 patients (54.2%), the lymphocele was symptomatic, requiring initial treatment by repeated needle aspirations or percutaneous drainage. Among 7 patients with persistence of the lesion treatment by sclerotherapy with doxycycline, povidone-iodine, and/or ethanol was successful in 4 cases who showed maximal lymphocele volume of 500 mL. Three other patients, namely, volumes of 120, 874, and 2298 mL were referred for surgery; in two cases, internal marsupialization was performed and in one case external drainage was necessary due to abscess formation. Mean time from the diagnosis to recovery in patients requiring surgical treatment was 15 (range, 8 to 24) weeks. Eleven patients with asymptomatic lymphoceles (mean volume 45 mL; range, 8 to 140) were monitored to resolution after a mean of 4 (range, 1 to 11) weeks.
  
  
  CONCLUSIONS
  All lymphoceles with the maximal volume exceeding 140 mL were clinically symptomatic. Initial percutaneous drainage with or without sclerotherapy was an effective method of treatment. Punctures, drainage, and sclerotherapy were not effective in patients with lymphoceles (>500 mL).
