What activities can or cannot be done while wearing a double J catheter?

A person with a double J catheter can lead a more or less normal life as long as the catheter allows. It is recommended to drink plenty of water or fluids and avoid holding the urge to urinate too much. As far as work is concerned, a double J catheter does not prevent you from working, as long as the work is not excessively physical. There would be no inconvenience in exercising, but it could have a series of consequences associated with it, such as blood with urine.
