Surgical complications following 1670 consecutive adult renal transplantations: A single center study.

BACKGROUND AND AIMS: The aim of the study was to clarify the frequency and the sequel of surgical complications occurring within 1 year after renal transplantation. PATIENTS AND METHODS: Surgical complications after 1670 consecutive adult kidney transplantations performed between 2000 and 2009 were retrospectively analyzed. In 2%, a living-related allograft was used, and 10% were retransplantations. An intravesical technique without stenting was used for the ureteric implantation.
RESULTS: There were 282 surgical complications occurring in 259 (15.5%) transplantations. Ureteral obstruction occurred in 53 (3.1%), lymphoceles in 39 (1.5%), postoperative hemorrhage in 36 (2.1%), and renal vein thrombosis in 22 (1.3%) patients, respectively. Out of the 17 lung emboli, 4 were fatal. Male recipients had twice as much ureteral stenosis as female (2.4 vs 1.2%, p < 0.05), and the opposite was true of urinary leakage (1.8% vs 4.0%, p < 0.025). Five-year patient and graft survival was impaired in patients with complications compared with patients without complications. Five-year patient survival was 92% versus 88% and graft survival 87% versus 74%.
CONCLUSION: Surgical complications impair patient and graft survival after kidney transplantation. © The Finnish Surgical Society 2015.
