ANATOMY

Detailed explanation-1: -Passing your urine happens when the brain tells the bladder muscle to tighten. This squeezes urine from the bladder. The brain then tells the sphincter muscles surrounding the urethra to relax. This lets the flow of urine go through the urethra and out of the body.

Detailed explanation-2: -LUTS can occur during bladder filling (storage), emptying (voiding), post urination or a combination. Storage symptoms are often irritative and can include urgency, frequent urination, frequent nighttime urination or involuntary loss of urine.

Detailed explanation-3: -Urination or micturition removes metabolic products and toxic wastes filtered from the kidneys and is a vital function of the human body. The micturition reflex requires a complex network of signals between the nervous system and the urinary tract system.
