First and second side openings are formed in an outer wall of the catheter body adjacent the distal tip portion and are in fluid communication with the first lumen and configured for passage of fluid therethrough. A stiffening insert is positioned in the distal tip portion and has a first stiffness greater than a second stiffness of the distal tip portion to facilitate entry into the abdominal cavity. The stiffening insert has a lumen therethrough communicating with the first lumen. A method for insertion of the dialysis catheter is also disclosed.
