A 50 year old man known to have diabetes since many years presents with poor urinary stream, hesitancy, difficulty in micturition and failure to void completely. What is he most likely suffering from?

The above mentioned clinical features of poor urinary stream, hesitancy, difficulty in micturition and failure to void completely are consistent with both BPH and autonomic neuropathy. Since the the patient is diabetic, he would most likely be suffering from diabetic autonomic neuropathy.
