[Effect of aging on detrusor function in males].
OBJECTIVE
The present study analyzed the effects of aging on detrusor function in the male.


METHODS
The study comprised 200 male patients with prostatism that had undergone complete urodynamic evaluation. The relation of patient age and the clinical and urodynamic data were analyzed.


RESULTS
Aging correlates with an increased urinary frequency and a reduced urinary volume and maximum flow rate. Bladder instability was significantly considerably more frequent in those over 80 years of age and the detrusor gradually manages lower maximum voiding pressures with increasing age. On the other hand, urodynamically diagnosed lower urinary tract obstruction and compromise of detrusor contractility are not age-dependent.


CONCLUSIONS
Aging is associated with changes in lower urinary tract function, such as increased urinary frequency, reduced urinary volume, bladder instability is more frequent, reduced maximum voiding pressures, but does not impair detrusor contractility.
