Impact of obesity on urologic complications among unrelated living donor kidney transplants.

ABSTRACT

PURPOSE: Although obesity has been associated with improved survival on dialysis, its effects on renal transplantation outcomes remain unclear. Herein we aimed to evaluate the effect of obesity on posttransplantation complications. PATIENTS AND METHODS: A retrospective analysis of consecutive renal transplant recpients from un related living donors was undertaken from 2006 to 2008. RESULTS: We included 180 patients, 34 (18%) were obese (body mass index >30 kg/m(2)) and 146 were lean. Obese patients were more likely to develope renal artery stenosis (17.6% vs 2.8%, p < 0.001), hematoma (47.9% vs 17.6, p = 0.009), wound complications (64.7% vs 9.6%, P < 0.001) and renal vein thrombosis(2% vs 0%, p < 0.001). Urologic complications consisting ureteral, ureteropelvic and ureterovesicular junction stenosis, wound bleeding, urinary leakage and renal artery thrombosis and also hospitalization time were found similar between the two groups. 2 year patiets and graft survival were not statististically different. CONCLUSIONS: Renal transplantation could be performed with reasonable urologic complications in obese patients.
