AbstractKetamine is widely used as an anesthetic during surgical procedures in both animals and humans. As its unique effects of inducing the dissociative hallucinatory,vivid dreams, out-of-body experiences, and delirium, it has diverted from legitimate uses to the illicit drug market, and abusing ketamine has become a serious social problem. The abusers may use ketamine alone or mixe it with other drugs to get an intense pleasure. There are case reports from all over the world in recent years that abusing ketamine may induce severe lower urinary tract symptoms (LUTS), and a variety of anatomical and functional lesions can be found in the urinary tract if further examinations are administrated. There is no universally recognized treatment protocols for this syndrome. Ketamine cessation or even reduction is the most effective treatment to prevent deterioration of the urinary tract, and intravesical instillation of hyaluranic acid (cystitstat) and oral pentosan polysulphate (elmiron) may take effect. The pathogenesis of ketamine-associated urinary tract destruction is unclear, and further study is needed.
