Urodynamic procedures: Recommendations of the Urodynamic Society. I. Procedures that should be available for routine urologic practice

Abstract

This report details the recommendations of the Urodynamic Society on urodynamic procedures. It was the unanimous opinion of the members of the task force that the practicing urologist should have access to cystometry, voiding cystourethrography, and estimation of urinary flow rate and postvoid residual urine volume. Knowledge of these parameters coupled with history, physical examination, and appropriate laboratory data permits effective treatment of the vast majority of patients with lower urinary tract disorders. Urethral pressure profilmetry, sphincter electromyography, and combined multichannel urodynamic procedures are not necessary for the routine practice of urology.

Injections of Botulinum Toxin A into the detrusor to treat neurogenic detrusor overactivity secondary to spinal cord injury

“…Before the BTX-A injections and 6 weeks after, patients were asked to keep a diary on incontinence, diuresis, CIC timing and the amount of anticholinergic medication during tapering. The urodynamic evaluation was performed at the outset and during the follow-up(6, 12 and 36 weeks) examinations, and variables were defined according to standards recommended by the International Continence Society(ICS) [10]. During the urodynamic assessments, special attention was given to the following key parameters: (1) the reflex volume (RV), which was defined as the infused volume at the start of the first reflex detrusor contraction during the filling phase, (2) the maximum detrusor pressure during voiding (MVP), (3) the bladder compliance, which was defined as the relationship between the change in bladder volume and the change in detrusor pressure (calculated by dividing the volume change by the change in detrusor pressure during the change in bladder volume) and (4) the maximum cystometric capacity (MCC), which was defined as the infused volume during involuntary voiding or the volume at the time that the investigator decided to stop filling (usually at 500 ml).…”

Clinical value of combined electrophysiological and urodynamic recordings to assess sexual disorders in spinal cord injured men

“…3, radiopaque, 8F) were used for urethrovesical and anorectal recordings, respectively. Proper localisation of the transducers within the bladder, bladder neck and external anal/urethral sphincter in relation to the anatomical landmarks of the pelvis were con¢rmed using an image intensi¢er [Blaivas et al, 1982;Rossier and Fam, 1986]. Slow bladder ¢lling (5 ml/min) via the recording catheter was used with a 24% contrast medium (3-acetylaminomethyl-5-acetylamino-2,4,6-triiodinebenzoic acid).…”

“…Drugs that could interfere with the urethrovesical function were discontinued at least 48^72 hr before examination. UEs were performed according to the recommendations of the Urodynamic Society [Blaivas et al, 1982]. Neurogenic bladder dysfunction was de¢ned according to the recommendations of the International Continence Society.…”
