Cadaver kidney transplantation and vascular anomalies: A pediatric experience

BACKGROUND. The incidence of donor kidneys with vascular anomalies ranges from 18% to 30%; such kidneys are usually at increased risk of vascular and urological complications. The aim of this study was to determine whether the use of cadaver kidneys with vascular anomalies would adversely affect posttransplant graft and patient outcome. METHODS. From October 1987 to January 2004, 241 patients underwent kidney transplantation in our pediatric surgery department. Vascular anomalies were noted in 77/241 grafts (31.9%); 50 (64.9%) had multiple renal arteries and 22 (28.5%) venous anomalies. Patients were divided into three groups: Group A (1 renal artery and vein, 1 arterial and venous anastomosis [n=161]), Group B (>1 renal artery or vein, 1 arterial and venous anastomosis [n=33]), and Group C (>1 renal artery or vein, >1 arterial and venous anastomosis [n=47]). We compared the three groups for: patient and graft survival, incidence of posttransplant acute tubular necrosis, vascular and u...
