## Caption

Your bladder wall is primarily made of the detrusor smooth muscle and can normally store around 400–600 mL of urine in adults.

Urinary retention = inability to voluntarily empty the bladder. 
Common causes include:

1. Reduced detrusor contraction due to parasympathetic nerve damage or blockade of M3 muscarinic receptors 
( e.g. antimuscarinic medications)

2. Neurological disorders affecting higher control centres or the spinal cord 
(e.g. stroke, multiple sclerosis, spinal cord injury) -> impairing coordination of micturition.

3. Bladder outlet obstruction
(e.g benign prostatic hyperplasia (BPH), urethral stricture, or bladder neck obstruction) -> preventing urine from flowing out.

Acute Management 
1st line : urinary catheterisation -> decompress bladder
