The term lower urinary tract symptoms (Engl. Lower urinary tract symptoms , LUTS ), also pathologies of the lower urinary tract , summarizes various complaints received by mostly elderly male patient in urine collection and emptying of the bladder may occur. Of the 12 million men in Germany who are over 50 years old, around 30% suffer from symptoms of the lower urinary tract that require therapy. This refers to the following symptoms: Delayed onset of emptying of the bladder despite a strong urge to urinate, the need to squeeze in order to empty the bladder (press micturition), the feeling that the bladder is not completely empty (sensation of residual urine), a weak stream of urine, dripping urine , long urination times and a renewed urge to urinate shortly after urinating. The urge to urinate sometimes starts so suddenly that the toilet cannot be reached in time. This is known as urge incontinence .

Possible causes, about which a urological examination can provide information, are an enlarged prostate ( prostatic hyperplasia ), an inflammation or a tumor of the urinary bladder or prostate and a narrowing of the bladder neck with a normal sized prostate. Treatment depends on the cause.

In cats, a corresponding disease complex of the lower urinary tract is called Feline Lower Urinary Tract Disease .
