All were divided as adult (18\u201359\u2009years) and elderly (\u2a7e60\u2009years) groups. Various clinical, biochemical, and radiological parameters including doppler assisted vascular mapping were recorded. AVF was created by side to side anastomosis. Clinical and doppler assessment like blood flow and wall shear stress (WSS) were done at 4th, 6th, and 12th\u2009weeks. Radiological maturation of AVF was defined as combination of blood flow of \u2a7e500\u2009mL\/min and vessel diameter of 5\u2009mm. At 12\u2009weeks, maturation of both group and association of biochemical factors with primary AVF failure were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 120 patients (60 in each age group) were included.

Radio cephalic AVF (RCAVF) was common in both group, adult (85%) and elderly (76.5%), however elderly have more brachiocephalic AVF (BCAVF) (14.8% vs 23.3%).
