An adjustable length sheath and a method for adjusting the length of a sheath is disclosed. The adjustable length sheath is primarily designed for uretral access, and for the insertion of a dilator or other medical equipment. The adjustable length sheath has a proximal end with circumferential grooves cut lateral to the axis of said sheath such that it is possible to snap off a portion of the proximal end to adjust the length of the sheath. The proximal end may have a lower degree of flexibility than the main body of the sheath to allow the end to be more easily broken and may be made from a different, less flexible material, than the main body of the sheath.
