Detrusor muscle is found in the urinary bladder.
urinary bladder
The muscle that compresses the urinary bladder during micturition is the detrusor muscle. This smooth muscle layer surrounds the bladder and contracts to expel urine from the bladder into the urethra. The contraction of the detrusor muscle is primarily controlled by the autonomic nervous system, specifically the parasympathetic division.
Overactive bladder
The majority of the bladder is made of detrusor muscle. This muscle is told by the nervous system to contract when it expands. This is what causes the feeling of needing to urinate. In order to urinate the involuntary muscle the internal sphincter, and the voluntary muscle the external sphincter must both be opened. The detrusor muscle moves involuntarily, so the bladder would probably considered an involuntary muscle.

The main muscle in the bladder is called the Detrusor muscle (which is a smooth muscle). it is circular.
"Widely invasive with multiple foci of deep detrusor muscle invasion" refers to a type of cancer, likely bladder cancer, that has extensively spread into the detrusor muscle, which is responsible for bladder contraction. The term "multiple foci" indicates that there are several distinct areas of invasion within the muscle layer. This suggests a more aggressive disease with a higher likelihood of affecting surrounding tissues and a potentially poorer prognosis. Such findings typically necessitate more aggressive treatment approaches.
The detrusor muscle is the main muscle within the bladder that contracts during urination to help expel urine. It is a smooth muscle that forms a triangular shape at the base of the bladder.
The stomach has 3 muscle layers that help to churn and break down food.
