Abstract

Objectives: This study aimed to investigate the possible role of different donor and recipient vessel and ureteral anastomoses on survival and functional outcomes in en bloc kidney transplants. Materials and Methods: This retrospective cohort included 99 en bloc kidney transplants performed from December 2005 to March 2022. Recipients were grouped based on donor’s vessel (distal [n = 84] or proximal [n = 15] abdominal aorta), recipient’s vessel (abdominal aorta [n = 3], external [n = 21], internal [n = 50], or common [n = 25] iliac artery), and ureteral anastomosis (separate [n = 32] or common [n = 67]). Patient and graft survival, complication rates, and estimated glomerular filtration rate trends were compared between groups. Results: Pediatric brain dead donors had a mean age and weight of 37 ± 22 months and 14 ± 4 kg, respectively. Donor and recipient vessel and ureteral anastomoses did not affect overall survival (P = .306, .296, and .225), graft survival (P = .720, .172, and .124), and vascular (P = .347, .689, and .264) and urinary (P = .587, .172, and .385) complication rates. Lymphoceles requiring intervention were significantly more prevalent in the recipient external iliac artery group (P = .008) but were independent of donor vessel and ureteral anastomosis (P = .587 and 1.00). Estimated glomerular filtration rate trend was independent of donor (P = .921) and recipient vessel (P = .878 and .536). Conclusions: We found that different arterial and ureteral anastomoses appear to have comparable outcomes in en bloc kidney transplant with the exception of recipient external iliac artery, which may be slightly inferior because of the relatively higher rate of lymphoceles requiring intervention. © Baskent University 2024 Printed in Turkey.
