National audience. OBJECTIVES: To conduct a literature review on the role of urinary biomarkers in the initial assessment and follow-up of lower urinary tract symptoms. METHODS: A literature review was conducted in August 2014 using the Medline/Pubmed database limiting the search to work in English or French. RESULTS: Most studies were of level of evidence 2 or 3 (prospective cohort, controlled or not) and mainly about overactive bladder and bladder pain syndrome. Nerve Growth Factor (NGF) was the most studied and apparently the most promising in the evaluation of overactive bladder (OAB) and neurogenic detrusor overactivity (NDO). Urinary levels of ATP, prostaglandin E2 (PGE2), Brain-Derived Neurotrophic Factor (BDNF) and some cytokines were also significantly higher in most studies in patients with NDO or OAB. Epidermal Growth Factor (EGF), Heparin-Binding EGF (HBEGF) and Antiproliferative Factor (APF) were the most studied urinary markers in bladder pain syndrome, with a significant increase (EGF APF) or decrease (HBEGF) in cases of interstitial cystitis (compared to healthy controls). The urinary N-terminal-telopeptide (NTx) could be predictive of a failed mid-urethral sling. However, few studies reported the diagnostic values of the markers, their association with urodynamic parameters were rarely evaluated and the existence of a publication bias is likely. No randomized controlled study has so far compared the urinary markers to urodynamic evaluation. CONCLUSION: In the future, urinary markers could complete or replace urodynamic examination. However, to date, there is no high level of evidence study comparing these markers to urodynamics and their use can therefore not be recommended in daily practice.
