RT Journal Article SR Electronic T1 Ketamine bladder syndrome: an important differential diagnosis when assessing a patient with persistent lower urinary tract symptoms JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2012006447 DO 10.1136/bcr-2012-006447 VO 2012 A1 Shalom Srirangam A1 Joe Mercer YR 2012 UL http://casereports.bmj.com/content/2012/bcr-2012-006447.abstract AB The recreational use of ketamine is increasing in popularity due to its dissociative and paralytic effects, ease of availability and low cost. However, serious and frequently irreversible damage to the urinary tract is a recently recognised side effect of recreational ketamine use. The authors present a case of a young male patient with a 2-year history of troublesome lower urinary tract symptoms and a 5-year history of ketamine consumption. Medical management of such patients is largely limited to analgesia alone, and cessation of ketamine use before irreversible damage occurs remains the best means of avoiding the radical reconstructive surgery required in end-stage disease. This case and an accompanying review of the available literature illustrate the importance of early recognition of ketamine bladder syndrome in recreational users.
