Abulseoud A, et al. – This study was sought to evaluate the impact of adding low dose trospium chloride with transcutaneous posterior tibial nerve stimulation (TPTNS) in the treatment of overactive bladder (OAB) in females after failure of behavioral therapy. In the treatment of OAB in females, transcutaneous posterior tibial nerve stimulation combined with low dose trospium chloride considered as a more feasible than transcutaneous posterior tibial nerve stimulation alone.
