5. To effect dynamic tamponade, inflate the balloon with 10-12 ml of dilute contrast medium. Only
moderate pressure is required for tamponade.
6. Replace the stent-to-catheter adapter or side-arm adapter, and the Tuohy-Borst adapter, and adjust
the length of the stent in the ureter as desired. Secure the locking cap on the stent-to-catheter adapter
or side-arm adapter finger tight around the stent. NOTE: Since the distal 33 cm of the Kaye stent is
sideported, the stent may be advanced fully into the bladder, thereby enhancing drainage from
the renal pelvis into the bladder.
7. Check positioning of balloon catheter and stent with fluoroscopy. If satisfied, remove the stylet and
working wire. NOTE: Leave the safety wire and/or safety wire catheter in situ so that if you
wish to replace the catheter after removal, or the catheter should become dislodged, access is
maintained.
8. Reconfirm position with an intraoperative nephrostogram.
9. To dress, place 4x4's and lap pads so the tube is gently bent. Place tape (Micro-Foam is best) over
another pad (Figure B).
NOTE: Do not place tape directly on balloon.
NOTE: Leave the inflation valve in an accessible position so the balloon can later be deflated
without disturbing the dressing.
10. Lock one leg of the Y-connecting tube onto the side-arm fitting for nephrostomy drainage. Lock the
other leg onto the Tuohy-Borst adapter secured on the end of the stent for stent lumen drainage
(Figure C).
