The use of urethral catheterization in surgery can trace its root to 19th century military surgeons utilizing them to prevent urinary retention after morphine use, and to minimized complications after spinal cord injury [1]. It has become a common surgical practice to place urinary catheters in patients during many interventions [2, 3]. This practice has little support in evidence based literature [4, 5]. In theory a urinary catheter is place to drain the bladder and avoid complications such as over dilatation of the bladder which may result in dystonia [2, 6]. These complications are not well demonstrated in their occurrence and have been poorly examined in short procedures, defined here as those interventions planned to take less than six hours [5, 7].
