AIMS: To quantitatively evaluate the urinary symptoms at different stages of idiopathic Parkinson's disease (IPD) severity and its relation to urodynamic parameters. METHODS: This study was conducted on 49 patients with probable IPD to quantitatively evaluate their urinary symptoms using International Prostate Symptom Score and urodynamic tests. Four, 10, 29, 5, and 1 cases were classified as stages 1-5, respectively, according to Hoehn and Yahr staging of IPD severity. RESULTS: The most prevailing urinary symptom in IPD was nocturia (77.5%) followed by urgency (36.7%) and frequency (32.6%). Urodynamic tests revealed neurogenic detrusor overactivity in 33 patients (67.3%), detrusor underactivity in 6 patients (12.2%), and 10 (20.4%) patients with normal detrusor function. Irritative symptom index score correlated significantly with disease severity as well as the volume at initial desire to void and maximum bladder capacity meanwhile obstructive symptom index score had no significant correlation with any of the urodynamic parameters or disease severity. Total IPSS symptoms score significantly correlated with quality of life score. The mean of urodynamic parameters did not differ in IPD patients who did or did not receive anticholinergic or dopaminergic drugs. CONCLUSION: The irritative urinary symptoms manifested urodynamically as neurogenic detrusor overactivity are more common in IPD patients than obstructive symptoms. These irritative symptoms deteriorate progressively with the disease severity and significantly affect the quality of life of these patients. The International Prostate Symptom Score is a valuable tool in evaluating the urinary dysfunction in such patients. © 2011 Wiley-Liss, Inc.

Is lumbar spondylosis a cause of urinary retention in elderly women?

J Neurol. 2005 Aug;252(8):953-7

OBJECTIVES: Lumbar spondylosis (LS) is a common spinal degenerative disorder which causes various types of lower urinary tract dysfunction (LUTD). However, it is not certain whether LS may cause urinary retention in elderly women. METHODS: In a period covering the past 3 years, we retrospectively reviewed: a) urodynamic case records of women with urinary retention (post-void residuals, PVR > 100 ml), b) the records of women with LUTD due to LS (cauda equina syndrome and spinal canal narrowing by MRI), and c) uro-neurological features of women who belonged to both a) and b). RESULTS: a) One-hundred women with a mean age of 58 years had urinary retention. The most common underlying disease was multiple system atrophy [19], followed by multiple sclerosis [13] and cervical/thoracic tumours [8]. LS was the fourth most common [5], with the highest age (71 years) of all diseases. b) Nineteen women with LUTD had LS (12, canal narrowing of 50-70%; 7 > 70 %), with a mean PVR volume of 60 ml. A fourth [5] of them had urinary retention, with severe spinal canal narrowing (all 5 > 70%). c) Thus, 5 women belonged to both a) and b). In 4 of these women, LUTD followed or occurred together with typical cauda equina syndrome symptoms such as sciatica and saddle anesthesia. However, one elderly woman presented with painless urinary retention, and absent ankle reflexes were the sole neurological abnormality. The urodynamic abnormalities underlying urinary retention included an underactive detrusor in all 5, bladder sensory impairment in 3, an unrelaxing sphincter in 2, a low compliance detrusor in one, neurogenic sphincter motor unit potentials in 2 of 4 studied, and cholinergic supersensitivity of the detrusor in one of 3 studied. Surgical decompression ameliorated urinary retention in 1 of 2 women who had surgery. CONCLUSIONS: In our series, only 5 percent of the women with urinary retention had LS, but LS poses a potential risk for retention, particularly in elderly women with severe spinal canal narrowing. Preganglionic somato-autonomic dysfunctions underlie this condition. It may appear as the sole initial complaint in cases in which no other obvious neurological abnormalities are found.

Urodynamics in women from menopause to oldest age: What motive? What diagnosis?

Int Braz J Urol. 2011 Jan-Feb;37(1):100-7

Authors: Valentini FA, Robain G, Marti BG

Purpose: To analyze age-associated changes as a motive for urodynamics and urodynamic diagnosis in community-dwelling menopausal women and to discuss the role of menopause and ageing. Materials and Methods: Four hundred and forty nine consecutive menopausal women referred for urodynamic evaluation of lower urinary tract (LUT) symptoms, met the inclusion criteria and were stratified into 3 age groups: 55-64 years (A), 65-74 years (B), and 75-93 years (C). Comprehensive assessment included previous medical history and clinical examination. Studied items were motive for urodynamics, results of uroflows (free flow and intubated flow) and cystometry, urethral pressure profilometry, and final urodynamic diagnosis. Results: The main motive was incontinence (66.3%) with significant increase of mixed incontinence in group C (p = 0.028). Detrusor function significantly deteriorated in the oldest group, mainly in absence of neurological disease (overactivity p = 0.019; impaired contractility p = 0.028). In the entire population, underactivity predominated in group C (p = 0.0024). A progressive decrease of maximum urethral closure pressure occurred with ageing. In subjects with no detrusor overactivity there was a decrease with age of detrusor pressure at opening and at maximum flow, and of maximum flow while post void residual increased only in the C group. Conclusion: In our population of community-dwelling menopausal women, incontinence was the main motive for urodynamics increasing with ageing. A brisk change in LUT function of women older than 75 years underlined deterioration in bladder function with a high incidence of detrusor hyperactivity with or without impaired contractility while change in urethral function was progressive. Effect of ageing appears to be predominant compared to menopause.

Alteration of autonomic function in female urinary incontinence.

Alteration of autonomic function in female urinary incontinence.

Int Neurourol J. 2010 Dec;14(4):232-7

Authors: Kim JC, Joo KJ, Kim JT, Choi JB, Cho DS, Won YY

Stress urinary incontinence (SUI) and urge urinary incontinence (UUI) have different mechanisms of action. We believe that alteration of autonomic nervous system (ANS) activity may contribute to UUI because the lower urinary tract is regulated through the sympathetic and parasympathetic nervous systems. Heart rate variability (HRV) allows measurement of autonomic nervous function, therefore we measured and compared HRV parameters in women with urinary incontinence.
