DISCUSSION Many surgeons default to holding the scope in a curved position. Due to the length and the ever decreasing calibre of modern scopes, the transmission of torque is reduced, resulting in decreased rotation of the tip in response to movements of the hand. Consequently, the operator resorts to excessive movements in a ‘windscreen wiper’ motion. Using this technique improves the ability of the surgeon to control the rotation of the scope and to perform flexible ureterorenoscopy with economy of movement in a safe and efficient fashion.
