1. A urinary catheter assembly comprising:
a catheterization aid comprising a handle extending between a distal end of the catheterization aid and a proximal end of the catheterization aid, the handle having first and second walls extending from the proximal end and the distal end, and a guide channel formed between the first and second walls and within an interior of the handle;
an intermittent catheter comprising a distal catheter end and a proximal catheter end, with the intermittent catheter retained within the guide channel;
an orifice formed through the first wall of the handle, the orifice defining a lumen extending through the thickness of the first wall such that the lumen is in fluid communication with the guide channel; and
a transfer element including a string and a pull ring, a portion of the string extending into the lumen and coupled at one end to the distal end of the intermittent catheter, and another end of the string located outside of the handle and coupled to the pull ring;
wherein the proximal end of the catheterization aid provides an insertion guide adapted to facilitate insertion of the proximal catheter end into a urethra;
wherein, when the user pulls on the proximal portion of the transfer element, the proximal catheter end of the intermittent catheter moves in a first direction out of the guide channel to exit the insertion guide of the catheterization aid.
