Through a needs-based approach we sought to reduce instrument drops during endourological surgery. To this end, we designed and validated an endourology equipment organization device: the cord caddy. Iterative computer aided design and fused deposition model prototyping lead to the development of a machined functional prototype to accommodate the wide-variety of cables, cords, wires and equipment used in endourologic cases. Over 20 consecutive endourological surgeries, use of the cord caddy demonstrated that it met most of the design requirements, aside from disposability and basket/ureteroscope storage. Assessment of these requirements was precluded by the inability to test a sterile version of the device at our institution. Future plans include validating a sterile disposable device in the operating room.
