The role of urethral pressure profile on treating premature ejaculation by tamsulosin

Dear Editor, I am Dr. Hui-Rong Chen, from the Department of Urology in Shanghai First People＇s Hospital at Shanghai Jiao Tong UnNersity, Shanghai, China. Premature ejaculation （PE） is a common sexual dysfunction, affecting approximately 20%-30% of sexually active men. According to intravaginal ejaculatory latency time （IELT） of l min, the incidence is approximately 1%-3%.1 PE is significantly associated with many personal and negative consequences, such as distress, frustration, and avoidance of sexual intimacy due to the inability of successful delayed ejaculation, α1-adrenergic blockers were effective in delaying ejaculation in approximately 50%-67% of the cases.2,3 Recently, abnormal ejaculation, an adverse infrequent side effect associated with the use of α1A-adrenergic blockers such as silodosin or tamsulosin, has drawn significant attention. Clinical studies suggested that this represents a relative anejaculation rather than a retrograde ejaculation. We present here the study to investigate the role of urethral pressure profile （UPP） on treating PE by tamsulosin.
