Creation of a false passage due to forced catheterization, mucosal and submucosal tears from balloon inflation in an inappropriate location within the urethra.
3. Required Equipment
16Fr Foley catheter
18-gauge intravenous (IV) catheter (angiocath)
0.035Fr (0.89mm) Radiofocus® Glidewire®
4. Procedure
Insert the IV catheter (angiocath) through one of the side holes of the Foley catheter, directing it centrally.
Advance the 0.035Fr Glidewire® through the angiocath lumen until approximately 2–3 cm of the wire is exposed from the hole.
Remove the angiocath, leaving the Glidewire® within the Foley catheter.
If resistance is encountered while advancing the wire inside the catheter, applying water or saline to the wire and catheter tip can facilitate easier advancement.
Carefully retract the Glidewire® until the exposed part can pass centrally through the Foley catheter’s side hole.
Confirm the distal exposure of the Glidewire® and, while holding it, insert the Foley catheter with the wire into the bladder.
One primary limitation and potential complication of inserting a guidewire into the bladder is the possibility of incorrect placement. → Therefore, using ultrasound to confirm the placement of the guidewire in the bladder can help prevent potential complications.
After confirming the placement, perform balloon inflation, remove the guidewire, and secure the catheter.
