Retrograde semen after minimally invasive surgery for prostate enlargement can be treated with medication and surgery. 1. Drug treatment: minimally invasive surgery for prostate enlargement is a surgery that removes the prostate gland completely and stops bleeding precisely. After the surgery, due to the incomplete closure of the sphincter, semen will enter the bladder along the urethra during ejaculation, resulting in retrograde semen. It can be treated with medicines such as Midodrine Hydrochloride tablets and Diosmin tablets as prescribed by the doctor. 2. Surgery: If the effect of medication is not obvious, bladder neck reconstruction can be carried out to increase the resistance of the bladder neck, so that the semen will be discharged from the urethra in the right direction. If the phenomenon of retrograde semen occurs after minimally invasive surgery, the patient should go to the regular hospital in time to seek medical treatment. Usually pay attention to proper rest, eat more easily digestible food, prevent constipation, do not engage in strenuous exercise too early.
