Knowledge of how changes in bladder volume and the urge to void affect brain activity is important for understanding brain mechanisms that control urinary continence and micturition. This study used PET to evaluate brain activity associated with different levels of passive bladder filling and the urge to void. Eleven healthy male subjects (three left- and(More)
Micturitional histories were taken from 39 patients with acute brainstem stroke. Within 3 months from onset, 49% had irritative as well as obstructive urinary symptoms, the most common being voiding difficulty and nocturnal urinary frequency in 28%, followed by urinary retention in 21%. Urodynamic studies of 11 symptomatic patients revealed detrusor(More)
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(More)
OBJECTIVES Urinary dysfunction and orthostatic hypotension are the prominent autonomic features in multiple system atrophy (MSA). A detailed questionnaire was given and autonomic function tests were performed in 121 patients with MSA concerning both urinary and cardiovascular systems. METHODS Replies to the questionnaire on autonomic symptoms were(More)
OBJECTIVES To perform a randomized comparative study investigating the urodynamic effects of functional magnetic stimulation (FMS) and functional electrical stimulation (FES) on the inhibition of detrusor overactivity. METHODS Thirty-two patients with urinary incontinence due to detrusor overactivity (15 men, 17 women; age 62. 3 +/- 16.6 years) were(More)
Objectives—Urinary dysfunction is a prominent autonomic feature in Parkinson’s disease (PD) and multiple system atrophy (MSA), which is not only troublesome but also a cause of morbidity in these disorders. Recent advances in investigative uroneurology oVer a better insight into the underlying pathophysiology and appropriate management for urinary(More)
Micturitional histories and urodynamic studies were performed in 72 acute hemispheric stroke patients. Within 3 months from the onset, 53% of the patients had urinary symptoms including irritative as well as obstructive, and the most common symptom was nocturnal urinary frequency in 36%, which was followed by urge urinary incontinence in 29% and difficulty(More)
Bladder dysfunction (urinary urgency/frequency) and sexual dysfunction (erectile dysfunction) are common nonmotor disorders in Parkinson's disease (PD). In contrast to motor disorders, genitourinary autonomic dysfunctions are often nonresponsive to levodopa treatment. The brain pathology causing the bladder dysfunction (appearance of overactivity) involves(More)
OBJECTIVES Machado-Joseph disease (MJD), or hereditary spinocerebellar ataxia type 3, is the most common dominantly inherited ataxia. However, lower urinary tract (LUT) dysfunction in MJD has not been fully delineated. We investigated LUT dysfunction in MJD by clinical-urodynamic observations. METHODS In 24 genetically diagnosed MJD, we recruited all 11(More)
BACKGROUND Constipation is a prominent lower gastrointestinal tract dysfunction that occurs frequently in Parkinson's disease (PD). OBJECTIVE To investigate colonic transport and dynamic rectoanal behaviour during filling and defecation in patients with PD. METHODS Colonic transit time (CTT) and rectoanal videomanometry analyses were performed in 12(More)
