A basic understanding of urodynamics

Abstract

Urodynamic investigations provide a valuable tool to aid diagnosis and management of lower urinary tract symptoms by evaluating bladder function during the filling, storage and voiding phases. As well as covering basic urinary tract anatomy and physiology, this article provides a comprehensive overview of urodynamic principles, from a gynaecological perspective. It discusses an overview of the various different tests including cystometry, uroflowmetry and pressure flow studies including understanding abdominal pressure, bladder pressure and detrusor pressure significance. It provides case studies that include useful tips for interpreting urodynamic studies, including two single best answer questions, in order to aid professionals preparing for the MRCOG exam or those participating in urogynaecology clinics.
