[Research progress on mechanism and preventive measures of retrograde ejaculation after benign prostatic hyperplasia surgery].

Benign prostatic hyperplasia (BPH) is a common disease in middle-aged and elderly men. It's first-line therapy is drugs. But with the progression of the disease or side effects of drugs, surgical treatment will become a better choice. However, either transurethral resection of the prostate, the standard procedure, or enucleation or resection of the prostate based on various laser platforms or plasma technologies cause a high incidence of retrograde ejaculation in their postoperative follow-up. In the past, retrograde ejaculation was usually regarded as the cost of benign prostatic hyperplasia surgery. In recent years, with the continuous improvement of surgical skills and the emergence of new techniques, retrograde ejaculation has aroused the attention of clinicians. This article mainly introduces the mechanism of retrograde ejaculation after benign prostatic hyperplasia surgery and the methods to reduce the incidence of retrograde ejaculation after surgery. These methods mainly include various modified surgery, as well as novel minimally invasive techniques such as prostate embolization and prostatic urethral lift.
