My father is 85 years old, has parkinson s disease and just had his catheter removed after 6 months of wearing it. He fell and broke his hip on December 22, 2014, so has been in physical therapy with a catheter until today. He was told to go to the emergency room if he cannot urinate after 12 hours. Is there anything he can do to help him to urinate? He has taken flomax today, but is still unable to urinate. Please help.
