Detrus is a term that refers to the detrusor muscle, which is a smooth muscle found in the wall of the urinary bladder. The detrusor muscle is responsible for contracting and emptying the bladder during urination.

When the bladder is empty, the detrusor muscle is relaxed. As the bladder fills with urine, the detrusor muscle gradually contracts. This contraction is controlled by the autonomic nervous system, specifically the parasympathetic division. The parasympathetic nervous system stimulates the release of the neurotransmitter acetylcholine, which binds to receptors on the detrusor muscle cells and causes them to contract.

When it is time to empty the bladder, the detrusor muscle contracts more forcefully, while the urinary sphincter muscles at the outlet of the bladder relax. This coordinated action allows urine to be expelled from the bladder and passed out of the body through the urethra.

The function of the detrusor muscle is crucial for maintaining normal urinary continence and control. Issues with the detrusor muscle can lead to bladder dysfunction, such as overactive bladder or urinary incontinence. Various factors, including aging, nervous system disorders, and certain medications, can affect the function of the detrusor muscle.

Treatment for detrusor muscle-related conditions may involve behavioral modifications, medications, or, in some cases, surgical interventions. It is essential to consult with a healthcare professional, such as a urologist, to diagnose and determine the appropriate treatment for any bladder-related concerns.
