Croup is a condition that develops quickly in children and is usually caused by a viral infection in the upper airways, which is localised in the throat and surrounding tissues. It's characterised by a barking cough. It's fairly uncommon and affects more boys than girls.
However, depending on the type of catheter you had installed (a urethral or a suprapubic catheter), you may still experience some catheter pain, especially in the case of an indwelling catheter that is expected to stay in your bladder for awhile â usually from a few days all the way up to forever.
At the start of the procedure you'll be given a local anaesthetic to numb the area. Then a catheter â a fine, flexible, hollow tube â is passed into an artery in either your groin or your arm. At the tip of the catheter is a small inflatable balloon and a small tube of stainless steel mesh, called a stent. Some dye (contrast) is injected into the catheter so that your arteries can be seen on an x-ray screen. This helps show where the narrowings in your arteries are, and how severe they are.
