A general reduction in the number of autonomic nerves in detrusor smooth muscle of elderly patients with atonic bladder has been observed. There were no detectable differences in terms of voiding dysfunction, urge incontinence or detrusor instability between suburethral slings and abdominal or needle suspensions. There is still no effective drug therapy for the treatment of retention and no very effective drug treatment for unstable detrusor contractions. They block transmission of nerve impulses from sacral efferents to the detrusor muscles, inhibiting contraction. They involve regular contraction of perivaginal musculature and cause muscular hypertrophy and possibly inhibition of detrusor contraction by a local inhibitory neural reflex. In 20% of these patients incomplete voiding occurs due to dyssynergic contraction of the detrusor and sphincter muscles or due to mechanical outflow obstruction. With spinal cord pathology, incomplete bladder emptying may occur due to a combination of detrusor-sphincter dyssynergia and poor detrusor contraction during attempts at voiding. However, detrusor overactivity is present in up to half of continent elderly individuals. Other causes of bladder overflow obstruction such as urethral stricture and underactive detrusor muscle due to muscular or neurological disease are rarer. It is of little value in the management of incontinence due to detrusor instability or sphincter incompetence. Contractions of the detrusor muscle can also occur during filling of the bladder which cannot be inhibited. Oxybutynin with bladder retraining for detrusor instability in elderly people: a randomised controlled trial. Statistically, there was no significant correlation between the two tests: r = 0.177 and 0.258 for the patients with detrusor instability and stress incontinence, respectively. They are usually performed with filling cystometry which gives information about sensation, bladder capacity, compliance, the presence or absence of detrusor instability and incontinence. The bladder fills without an accompanying rise in pressure, due to relaxation of the detrusor muscle in the wall and the elastic properties of the connective tissue. The role of repositional surgery in detrusor instability is much reduced compared with surgery for stress incontinence, unless mixed incontinence is present where the stress element predominates.
