Fecal shedding followed by poor handwashing contaminates water and foods leading to infection of household and sexual contacts Stress incontinence - 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 - 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 - 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. functional incontinence - the patient is functionally able to reach the toilet in time because of impaired health or environmental conditions. Mechanism: problems in mobility resulting from weakness, arthritis, poor vision, or other conditions. Also environmental factors such as an unfamiliar setting, distant bathroom facilities, bed rails, or physical restraints.
