why are catheters used
I suppose you are referring to the urinary catheter. The hip surgery is going to render the concerned patient immobile for a few days. So, the urinary catheter is used to help drain the urine into the urine bag. Once the patient is able to walk to the toilet, the catheter is removed. So, basically, the catheter is just to aid the patient post surgery, during the recovery period. Written Jul 1, 2015.
