Most prevalent urinary symptoms in men are nocturia, which is defined as the need for a patient to get up at night on a regular basis to urinate, followed by frequency, weak stream, incomplete emptying, intermittency, which means that the urinary stream is not continuous, urgency, and straining to pass urine.
Nocturia is the lower urinary tract symptom with the greatest negative impact on quality of life.
Postvoid residual urine, which is the amount of urine retained in the bladder after a voluntary void, lower urinary symptoms, anxiety and depression were identified to be significant predictive factors of the health-related quality of life in men with BPH.
