Fifty five patients between 65 and 89 years old who had their urinary problems assessed by urodynamics study were reviewed. The most common urinary symptom among males was urge incontinence, while retention and urge incontinence occurred with equal frequency among females. The commonest cause of retention in males was bladder outlet obstruction, while atonic neurogenic bladder was the most common cause in females. Urge incontinence was strongly associated with an unstable bladder, small bladder volume and Parkinson's disease. Retention of urine, and an atonic neurogenic bladder strongly correlated with diabetes mellitus. Three patients (out of 31) with unstable bladders also had detrusor external sphincter dyssynergia. Of these, two had Parkinson's disease. Although three patients were thought to have stress incontinence after history and physical examination, only two had stress incontinence with detrusor instability on urodynamic studies. The last patient had atonic bladder with overflow.

Vesicosphincteric disorders are frequent in patients with Parkinson's disease, due to a lesion of the locus niger of the extrapyramidal tract which no longer secretes sufficient dopamine to activate the nigrostriatal tract. The commonest symptoms are urgent micturition, dysuria or a combination of the two. 50% of patients with Parkinson's disease present with disturbances of micturition and these symptoms may be presenting complaint of the disease in 10% of cases. Cystomanometry reveals detrusor hyperactivity in more than 60% of cases and hypoactivity in less than 30% of case, while dyssynergia is less common. Delayed relaxation of the striated sphincter may sometimes be observed. Urological problems must therefore be distinguished from urological problems in these patients. A combined urological and urodynamic assessment is essential as the risk of incontinence following prostate surgery is 20%. Stress urinary incontinence in women may mask or be associated with urgency. These vesicosphincteric disorders must therefore be treated cautiously with a combination of medical treatment (dopatherapy increases detrusor control), retraining and occasionally surgery after a detailed urodynamic assessment.

There are many causes of urinary incontinence in the female, with stress incontinence reported as the most common. However, a high incidence of detrusor instability has been described in incontinent patients with Parkinson disease. To assess this further, urodynamic studies were performed on 17 female patients with Parkinson disease and complaints of urinary dysfunction. Detrusor instability was demonstrated in the majority of the patients (70.6%). Of the 8 patients with specific symptoms of stress incontinence, 2 were found to have a stable bladder, 3 had a hyporeflexic bladder, and 3 had detrusor instability. Surgical therapy may not be appropriate for all patients in this group. Since it is difficult to determine the causation of urinary incontinence on the basis of symptoms alone, urodynamic studies can be helpful in the evaluation of incontinent patients. This is especially important in female patients with Parkinson disease who may have detrusor instability alone or in addition to anatomic stress incontinence.

The results of cystometrograms and ice-water tests (IWTs) were retrospectively evaluated in 557 patients with overactive bladders, lower motor neuron lesions or pure stress incontinence. The IWT was considered positive when, following ice-water instillation, the fluid was expelled from the bladder within 1 min. The test was considered false negative when no fluid escaped despite a sustained detrusor contraction of the same magnitude as the micturition contraction. Ninety-seven percent of patients with complete and 91% of those with incomplete upper motor neuron lesions had a positive or a false negative IWT. About 75% of the patients with multiple sclerosis, Parkinson's disease or previous cerebrovascular accident had a positive IWT. All patients with lower motor neuron lesions or pure stress incontinence had a negative IWT. There was a significant correlation between a positive IWT and an abnormal sensation of bladder filling and inability to inhibit micturition voluntarily, as well as between a negative IWT and the occurrence of phasic detrusor contractions during cystometry. The study shows that the IWT is a sensitive test for differentiating upper from lower motor neuron lesions. It is also a useful parameter for functional subdivision of overactive bladders. In patients with voiding dysfunction in the absence of lower urinary tract inflammation, a positive test is an indicator of a silent or overt neurological disorder.

Disturbances of micturition are very common in Parkinson's disease. Hence, we assessed 50 patients (22 female, 28 male, average age: 59.8 years) by means of the Gaudenz score. In 31 cases (62%) normal findings were obtained. Urge incontinence was diagnosed in 13 cases (26%) and stress incontinence in 5 patients (10%). One patient had both urge and stress incontinence. All patients with stress incontinence were female.

Although patients with Parkinson's disease (PD) experience pelvic organ dysfunction of the urinary bladder, bowel and genital organs, an accurate incidence of the dysfunction and its characteristics have yet to be ascertained. We devised a detailed questionnaire on these three pelvic organ functions in PD patients and control subjects, in our search for a hallmark that would distinguish between the two groups. The PD group comprised 115 patients; 52 men and 63 women, age range 35-69 (average 59) years old, average duration of illness 6 years, median Hoehn and Yahr stage 3. All were taking levodopa with/without dopamine agonists. The control group comprised 391 local individuals who were undergoing an annual health survey; 271 men and 120 women, age range 30-69 (average 48) years old. The questionnaire had three parts: bladder (nine questions), bowel (four questions), and sexual (three questions for women, five for men) function. Each question was scored from 0 (none) to 3 (severe) with an additional quality of life (QOL) index scored from 0 (satisfied) to 3 (extremely dissatisfied). The completion rate was 100% for bladder and bowel functions, whereas for sexual function, it was 95% (control) and 88% (PD) for men and 82% (control) and 60% (PD) for women. As compared with the control group, the frequency of dysfunction in the PD group was significantly higher for urinary urgency (women 42%, men 54%), daytime frequency (28%, 16%), nighttime frequency (53%, 63%), urgency incontinence (25%, 28%), retardation (44% of men), prolongation/poor stream (men 70%), straining (women 28%); constipation (63%, 69%), difficulty in expulsion (men 57%), diarrhea (men 21%); decrease in libido (84%, 83%), decrease in sexual intercourse (55%, 88%), decrease in orgasm (men 87%), and in men, decreases in erection (79%) and ejaculation (79%). The QOL index for the PD patients was significantly higher for bladder (27%, 28%) and bowel (46%, 59%) but not for sexual dysfunction, despite the group's high prevalence of sexual dysfunction. In the PD patients, fecal incontinence was associated with urinary incontinence. Stress urinary incontinence and a decrease in libido were more common in women than in men. Bladder and bowel dysfunction, but not sexual dysfunction increased with the Hoehn and Yahr stage. Sexual dysfunction, but neither bladder nor bowel dysfunction, increased with age. Patients taking levodopa and bromocriptine more frequently had bladder (voiding phase) dysfunction than those taking levodopa only. The findings show that bladder, bowel and sexual dysfunction are all prominent in patients with PD. Amelioration of pelvic organ dysfunction, particularly bowel dysfunction which most affects the quality of life, therefore should be a primary target in the treatment of patients with PD.
