Abstract:
Objective To evaluate the efficacy and safety of intravesical alkalised lidocaine therapy for the treatment of ketamine-associated cystitis. Methods From 2008 to 2009,7 cases of patients (6 males and 1 female; mean age 26 years) were admitted with severe lower urinary tract symptoms (LUTS). Three cases had painful hematuria. All cases had history of abuse ketamine. B ultrasound examination revealed marked thickness of the bladder wall and small bladder capacity. Urodynamic study were performed showing the functional bladder capacities between 20 to 100 ml(average 50 ml),Qmax between 3.7 to 10.8 ml/s, RUV between 0 to 24 ml. Urodynamic analyses showed hypersensitive bladder and decreased bladder compliance. Cystoscopy showed diffuse reddish swelling of the bladder mucosa and hemorrhagic cystitis. All patients were required to withdraw the ketamine and treated with bladder hydrodistention therapy (intravesical alkalised lidocaine with heparin). Results The biopsies of 2 patients showed bladder wall inflammation and fibrosis. LUTS was significantly relieved after bladder installation within 7 days. The functional bladder capacities increased between 150±30 ml,Qmax 11.5±3.8 ml/s. Four cases became asymptomatic. Three recurrent cases after reabused ketamin for 1 to 3 months received same intraversical treatment. All cases were followed up for 2 to 17 months. Conclusion Intravesical hydrodistention therapy with alkalised lidocaine and heparin could be the safe and effective therapy in the treatment of katamine-associated cystitis.
