Some of the elderly patients with prostatic hyperplasia have enlarged prostates that cause urinary obstruction or even urinary retention, requiring open surgery and surgical treatment to improve the quality of their birth words. Since each surgical method of removing the prostate has its own characteristics, the type and percentage of sexual dysfunction caused also varies. After surgery, some people may have an impact on sexual function, more commonly retrograde ejaculation and impotence, but not absolutely. Transurethral resection of the prostate, which involves removing the enlarged prostate tissue via the urethra with an electrodesiccoscope, is a less invasive and safer procedure that does not damage the nerves that control penile erection nor the blood supply to the penis, and has less impact on sexual function, with impotence occurring in only about 5% of patients. However, the operation may damage the internal bladder sphincter and the bladder neck, which may cause retrograde ejaculation. Of course, it can be avoided with good preoperative preparation and careful intraoperative cutting. The suprapubic transsphenoidal prostatectomy was originally the most widely used surgical method in clinical practice. Because this procedure requires incision of the anterior bladder wall, the tissue around the bladder neck may be affected, therefore, retrograde ejaculation may occur in patients who undergo this procedure. Patients with prostate cancer who undergo radical prostatectomy have a much higher chance of impotence after surgery than those with BPH because the extent of resection is greater than that of BPH, resulting in a significantly greater chance of nerve damage. However, this does not mean that patients who have had radical surgery cannot have sex again after surgery. As long as the patient recovers well after surgery and the penis is still able to get an erection, a moderate sexual life can be maintained.
