AIMS: Patients coming for urodynamics expect those delivering the service to be fully trained, with assurance of competence and quality. This document proposes a single UKCS Certification and Re-certification process for all health care professionals who perform or interpret urodynamics. METHODS: The Working Group of the United Kingdom Continence Society engaged with stakeholders in relevant professional societies and institutions, recirculating drafts until consensus was reached. RESULTS: A process of Certification has been designed to ensure that patients attending urodynamics undergo high quality investigations, the results of which are accurately interpreted, in order to guide both the patient and their clinicians in the patient's future management. CONCLUSIONS: The United Kingdom Continence Society strongly recommends that all urodynamic investigations are carried out by, or under the supervision of, certified individuals. This document presents such a process of Certification and Re-certification that aims to ensure that quality standards are maintained and that patients have high quality urodynamics.
