Acupuncture combined with herbal medicine and medications assists in the elimination of kidney stones that have lodged in the ureters. Jiangxi Jiujiang Hospital of Traditional Chinese Medicine researchers made two important findings. First, a combination of herbs and the drug tamsulosin (Flomax) enables the passage of kidney stones. Second, adding acupuncture to the herbal medicine and drug protocol significantly increases positive patient outcome rates. 
The results of the investigation have important clinical implications. The drug tamsulosin is an alpha-blocker used to ease urination. It relaxes the muscles of the bladder and prostate and causes dilation of the ureteral lumen. Currently, tamsulosin is FDA approved for improving urination for men with benign prostatic hyperplasia. The drug has also been used for the treatment of ureteric calculi (kidney stones that have already moved into the ureters).
