Stress incontinence - Answer✔️✔️-the urethral sphincter is weakened so that
transient increases in intra-abdominal pressure raise the bladder pressure to levels
that exceed urethral resistance. Causes include childbirth and surgery,
postmenopausal atrophy of the mucosa, and urethral infection. May follow prostate
surgery in men.
urge incontinence - Answer✔️✔️-detrusor contractions are stronger than normal and
overcome the normal urethral resistance. The bladder is typically small.
Mechanisms: Decreased cortical inhibition of detrusor contractions from stroke,
brain tumor, dementia, and lesions of the spinal cord above sacral level. Also
hyperexcitability of sensory pathways ie: bladder infections, tumors, and fecal
impaction. Deconditioning of voiding reflexes ie: frequent voluntary voiding at
low bladder volumes.
overflow incontinence - Answer✔️✔️-detrusor contractions are insufficient to
overcome urethral resistance, causing urinary retention. The bladder is typically
flaccid and large, even after an effort to void. Mechanisms: obstruction of the
bladder outlet ie: BPH or tumor. Weakness of the detrusor muscle associated with
peripheral nerve disease at S2-4 level. Impaired bladder sensation that interrupts
the reflex arc ie: diabetic neuropathy.
