Detrusor contractility in post-menopausal women: Impact of ageing, complaint and urodynamic diagnosis.

Introduction: Detrusor contractility (DC) can have a considerable impact on the management oflower urinary tract symptoms (LUTS). However, it is currently impossible to predict, based on clinical data alone, which woman has an impaired DC. Our aim was to determine if DC, assessed by projected isovolumetric pressure-1 (PIP1) and VBN contractility parameter k, was associated with age, main complaint, and urodynamic diagnosis in a population of older women.

Comparison of bladder voiding efficiency in women when calculated from a free flow versus an intubated flow.

Objectives: To assess the reproducibility of bladder voiding efficiency (BVE, Void%) between free flow (FF) and intubated flow (IF) and to correlate BVE measurements with urinary incontinence (UI) complaints and urodynamic (UDS) findings in women.

Methods: UDS recordings of women referred for LUTD evaluation to our UDS center were reviewed. Each file included FF at arrival, filling cystometry, and IF.

Detrusor after-contraction: a new insight.

Aims: Detrusor after-contractions (DAC) are non-common in adults. Both definition (nothing in ICS reports) and significance (artefact, link with detrusor overactivity (DO) or bladder outlet obstruction (BOO)) remain discussed. Our purpose was to carry out an analysis of the urodynamic parameters during voidings with DAC and, using the VBN model, to simulate pathophysiological conditions able to explain both voiding phase and DAC.

Contribution of behavioral and cognitive therapy to managing overactive bladder syndrome in women in the absence of contributive urodynamic diagnosis.

Overactive bladder (OAB) is a syndrome characterized by symptoms of urgency with or without incontinence, frequency, and nocturia. Pathophysiology of OAB is incompletely characterized. Therefore, there is great variability surrounding OAB evaluation.

Idiopathic and neurogenic detrusor overactivity: do the different patterns have urodynamic characteristics related to gender or neurological condition?

Objectives: To evaluate the urodynamic characteristics of the two patterns (phasic, P and terminal, T) of detrusor overactivity (DO) according to gender and neurological condition.

Materials And Methods: Urodynamic characteristics of DO were analysed in a population with proven urodynamic DO (127 women and 76 men, respectively with 48 and 43 neurological diseases (encephalic, incomplete medullar lesion or peripheral)). Phasic DO is characterized by phasic waves with or without leakage while terminal DO is defined by a single non-inhibited contraction resulting in incontinence.

Is a sequence of tests during urethral pressure profilometry correlated with symptoms assessment in women?

Introduction: Our purpose was, applying a strictly defined protocol for urethral profilometry, 1) to test the repeatability of same session rest maximum urethral closure pressure (MUCP) and 2) to search for correlation between women complaint and the changes in MUCP value (rest and dynamic tests).

Materials And Methods: A population of 140 consecutive women referred for evaluation of lower urinary tract dysfunction was stratified in 4 groups according with the urinary symptoms: stress, urge, mixed incontinence and continent and in each group in 3 age groups (young, middle age and old). The sequence of tests recorded in supine position was: urethral pressure profile at rest bladder empty, after bladder filling at 250 mL (reference test), stress profile, fatigability (before (rest) and after 10 successive strong coughs), then in standing position.

Phasic or terminal detrusor overactivity in women: age, urodynamic findings and sphincter behavior relationships.

Objectives: To search for relationships between phasic (P) and terminal (T) DO with age, urodynamic findings and sphincter behavior during involuntary detrusor contraction in woman.

Materials And Methods: Urodynamic studies (triple lumen catheter 7F, seated position) of 164 successive women referred for LUTS with diagnosis of DO were reviewed. Patients were stratified in 4 sub-groups: pre- (18-44 y), peri- (45-54 y), post-menopause (55-74 y) and oldest old (= 75 y).

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

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.

Urodynamics in a community-dwelling population of females 80 years or older. Which motive? Which diagnosis?

Purpose: To determine why community-dwelling women aged 80 years or over were referred for urodynamic evaluation despite their advanced age and which urodynamic diagnosis was made.

Materials And Methods: One hundred consecutive females (80-93 years) were referred to our urodynamics outpatient clinic for evaluation of lower urinary tract symptoms (LUTS) between 2005 and 2008. Clinical evaluation comprised of a previous history of LUTS, previous medical history of neurological disease or dementia, pelvic floor dysfunction or prior pelvic surgery.

Analysis of rhythmic rectal contractions during filling cystometry in women.

Purpose: Rhythmic or random rectal contractions independent of bladder activity are frequently observed during cystometry and usually attributed either to a neurological disease, or to ageing. The aim of our study was to search for an association of rhythmic rectal contractions (RRCs) with a specific lower urinary tract symptom or/and an urodynamic diagnosis.

Materials And Methods: The population consisted of 534 consecutive women with lower urinary tract symptoms and without specific gastro-intestinal disease referred for urodynamics; 382 (non-ND) had no history of neurological disease and 152 (ND) a history of neurological disease.

Differences between the data from free flow and intubated flow in women with urinary incontinence. What do they mean?

Aims: To assess the effects of a urethral catheter on the urodynamic data extracted from uroflow in women, and to interpret the differences from free uroflow using the VBN mathematical micturition model.

Methods: Urodynamic data of 217 consecutive (June 2002 to December 2004) women with urinary incontinence and without neurological disease or more than grade 2 prolapse were reviewed. Inclusion criteria were to perform one free flow (FF) and one intubated flow (IF) (voided volumes of at least 100 ml and continuous flow curves).
