There are toxic states in which the eliminating organs of the body, specifically the kidneys, are incapable of removing from the body at an adequate rate the natural or unnatural substances whose accumulation is detrimental to life. Though extrarenal methods of treatment of renal failure vary, extracorporeal hemodialysis remains the most efficient and rapid method. It is our purpose to present a double-lumen catheter as an important adjunct in hemodialysis, when the catheter is used as a venous cannula.

Methods and Material  The double-lumen catheter is made of a nontoxic vinyl plastic.* It is 60 cm in length with the distal 20 cm consisting of a single-lumen extension (Figure). The inside diameter of both lumina is 2.3 mm. The diameter of the double-lumen section is 6.6 mm. The catheter is made to fit the connectors of the Kolff disposable twin-coil unit.The catheter is inserted through a single cut-down incision
