Voiding symptoms include: hesitancy, intermittency, incomplete bladder emptying, weak urinary flow, and strain in urination. Storage symptoms include the need to urinate frequently, waking at night to urinate, urgency (compelling need to void that cannot be deferred) and a burning sensation. Until a few years ago, when the disease was predominantly treated through surgery, 20% of men over 50 years of age underwent partial resection of the prostate. Today, thanks to BPH drugs, in many cases it is possible to avoid or at least postpone surgery, reducing the symptoms.
