Final answer:
Bladder dystension after surgery is common due to multiple factors, including the weakening of the detrusor muscle, pressure from the uterus, and urinary incontinence.
Step-by-step explanation:
Bladder dystension is common after surgery due to various factors. First, the detrusor muscle, which contracts forcefully in young individuals, may weaken with age, leading to diminished bladder strength. Additionally, the downward pressure of the uterus during pregnancy compresses the urinary bladder, causing frequent urination. Lastly, stress urinary incontinence and urge urinary incontinence can occur after surgery, resulting in bladder problems. Stress urinary incontinence is caused by the loss of support of the urethra, while urge urinary incontinence is caused by uncontrolled contractions of the detrusor muscle in the bladder wall.
