Introduction:
Detrusor hyperactivity is the leading cause of urinary dysfunction in Parkinson's disease (PD). There are few studies correlating PD clinical aspects with this autonomic feature.
Methods:
A cohort of 63 women with PD were prospectively examined for assessment of clinical aspects and disease severity using unified Parkinson's disease rating scale and Hoehn-Yahr scale, respectively. The urologic function was evaluated by the urodynamic study. Two groups were categorized at this time - groups with and without detrusor hyperactivity. After seven years, the same parameters were re-evaluated.
Results:
Progression of the disease on mental scores was found in the group with detrusor hyperactivity. On follow-up, clinical symptoms and severity did not show significant worsening between the groups.
Conclusion:
Detrusor hyperactivity is a frequent urodynamic finding in PD, and even though it is associated with dopaminergic dysfunction, it cannot be blamed as a factor of worsening motor performance, but is probably associated with poor cognitive and mental prognosis.

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
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...
