It sounds like a neurogenic bladder is present. This can be caused by prolonged hospitalization, infection, medication side effects, or after a urological procedure.
It is possible that malaise caused by infection or medications can also lead to the neurogenic bladder.
Stopping any offending medication can be considered, and any urological infection treated.
You can consider further urodynamic testing to evaluate a cause of the bladder dysfunction - or a neurology referral to evaluate for any nerve damage.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
