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.
Conclusion:
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.

The Effect of Aging on Tissues
Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
