Methods： A total of 36 men with recalcitrant （TPPS refractory to multiple prior therapies were treated with the injection of a compound of Bupivacaine and Fentanyl （10 ml of 0. 125% Bupivacaine, 0.05 mg Fentanyl, 5 mg Dexamethasone, 100 mg Vitamin B1 and 1 mg Vitamin B12） into sacral space once a week for 4 weeks. The National Institute of Heahh Chronic Prostatitis Symptom Index （NIH-CPSI）, maximum and average flow rate were performed al the start and the end of 4 weeks＇ therapy. Results：Mean NIH-CPSI total score was decreased from 26. 5±1.6 to 13.4±2.0 （p〈0.001）. Significant improvement was seen in each subscore domain. A total of 32 patients （89%） had at least 25% improvement on NIH-CPSI and 22 （61%） had at least 50% improvement. Maximal and average flow rate were increased from 19. 5±3. 8 to 23. 6±4. 2 and 10. 9±2.6 to 14.3±2.4 respectively. Conclusion： Injection of this compound of Bupivacaine, Fentanyl and Dexamethasone into sacred spinal space is an effective and safe approach for recalcitrant CPPS. Further study of the mechanisms and prospective placebo controlled trials are warranted.展开更多
