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.
1 The cervix is cleansed with an antiseptic (which will cause a brief, cold sensation), and a thin, flexible tube (catheter) is then passed through the vagina and into the uterus.  A balloon at the tip of the catheter is inflated with saline to hold the device in place. Sterile saline is then infused through the catheter into the uterus. You may feel some mild to moderate cramping due to the saline infusion.
