Lymphocele in Kidney Transplantation: A Comparison of Ligation and Non-ligation Technique of Iliac Lymphatic Dissection

To compare the incidence of lymphocele in kidney recipients following 2 lymphatic vessel division techniques: ligation and non-ligation.Retrospective reviews of the records of 402 patients with end-stage renal disease who underwent kidney transplantation from April 2015 to December 2019 at Siriraj Hospital.Four hundred two patients were included in the study: 54.9% of the patients were male, and the patient's mean age was 41 years. There were 25.1% and 74.9% that received kidney grafts from living and deceased donors, respectively. The preoperative renal replacement therapies were 83.3% hemodialysis, 12.9% peritoneal dialysis, and 3.7% preemptive transplantation. Two hundred forty-nine patients received lymphatic division with the ligation technique and 153 patients received the non-ligation. Lymphoceles were found in 31 cases (7.7%). Lymphocele occurrence in the ligation group was lower than in the non-ligation group: 5.2% compared to 11.8% (P value = .017). There were 22.6% of lymphoceles that had a spontaneous resolution with no treatment.The ligation of iliac lymphatic vessels during division reduced the incidence of lymphoceles non-ligation.
