In a healthy urinary tract, this mechanism ensures that the bladder completely empties with little pressure and that no residual urine remains in the bladder.

Why does bladder hold urine?

People may retain urine because bladder muscle contractions are impaired, the opening of the bladder is blocked (bladder outlet obstruction), or there is a lack of coordination between bladder contraction and relaxation of the muscle that closes the opening of the bladder (urinary sphincter).

What triggers the urinary reflex?

When the bladder is full of urine, stretch receptors in the bladder wall trigger the micturition reflex. The detrusor muscle that surrounds the bladder contracts. The internal urethral sphincter relaxes, allowing for urine to pass out of the bladder into the urethra. Both of these reactions are involuntary.

What is bladder made of?

It is composed of connective tissue with elastic fibers. The next layer is the muscularis, which is composed of smooth muscle. The smooth muscle fibers are interwoven in all directions and, collectively, these are called the detrusor muscle. Contraction of this muscle expels urine from the bladder.
