The role of urodynamics in females with lower urinary tract symptoms

Abstract

Objective: To review the role of urodynamic studies (UDS) in females with lower urinary tract symptoms (LUTS), as LUT dysfunction is a common condition. The role of UDS was and continues to be vital in the assessment of such cases; however, utilisation is still debated amongst clinicians as to when and in which conditions it should be used. Materials and methods: We conducted a literature review using the Medical Literature Analysis and Retrieval System Online (MEDLINE) search engine from year 1990 until August 2018, using the keywords: ‘female urology’, ‘lower urinary tract symptoms’, ‘urodynamic’, ‘incontinence’, ‘overactive bladder’, ‘bladder outlet obstruction’. We also reviewed the latest international guidelines related to the subject including: the International Consultation of Incontinence, American Urological Association, European Urology Association, and International Continence Society. Results: Using >60 reference articles and international guidelines, our review showed that there is a trend of utilisation of UDS in females with LUTS. Conclusion: UDS remains a valuable diagnostic test, which provides vital information to both the surgeon and patient prior to invasive treatment, with minimal morbidity.
