to guide through the body into the desired fluid passage referring now to fig6 catheter pusher 46 is shown catheter pusher 46 is preferably composed of polyethylene however other suitable biocompatible materials may be used in operation the length of the fluid passage to be drained is measured elongated tubular member 12 is trimmed at the desired length to form end 18 adapter means 20 is then inserted into lumen 32 of end 18 to form a complete ureteral connector stent 10 ureteral connector stent 10 may be inserted in this form during open surgery to insert ureteral connector stent 10 endoscopically a kit including guidewire 42 and catheter pusher 46 will normally be provided guidewire 42 is inserted through lumen 32 of retaining means 22 adapter means 20 straight tube 17 and retaining means 16 to abut plug 35 of retaining means 16 ureteral connector stent 10 is thereby straightened for ease of insertion into the desired fluid passageway guidewire 42 and stent 10 are inserted through a cystoscope into the urogenital passage catheter pusher 46 is inserted through the cystoscope and held against end 23 of retaining means 22 until proper placement has been achieved guidewire 42 is removed and then catheter pusher 46 is removed catheter stent 10 will be in proper position with retaining means 16 in the kidney and retaining means 22 in the bladder this can be verified radiographically because.
