Abstract

Abstract: Urodynamic investigations are an important tool aiding the clinical management of patients with lower urinary tract symptoms, such as overactive bladder, urinary incontinence, and voiding dysfunction. Urodynamic investigations can be non-invasive or invasive. Non-invasive tests include uroflowmetry and ultrasound measurement of post-void residual urine volumes. Invasive tests involve urethral catheterization to measure bladder pressure, and placement of a catheter either in the vagina or the rectum to measure abdominal pressure. The detrusor pressure is obtained by subtracting abdominal pressure from bladder pressure. Invasive urodynamics carry a low risk of urinary tract infection. The International Continence Society has published standards on good urodynamic practice and the terminology of lower urinary tract function. Urodynamic investigations should be performed by a trained clinician who can understand urodynamics on a physical and technical level, as well as the physiology and pathophysiology of the lower urinary tract.
