Laparoscopic prostate surgery can preserve sexual organs for patients with early prostate cancer without metastasis; if the patient has advanced prostate cancer and the cancer has metastasis, it is recommended not to preserve the function of sexual organs. Lumpectomy is a minimally invasive surgery for prostate cancer, which is less traumatic, with less blood loss during the operation and quicker recovery after the operation, and the main complications are urinary incontinence and sexual dysfunction. However, for early prostate cancer without metastasis, the surgical method of preserving sexual nerves can be adopted, which can preserve the sexual function. For patients with invasion of seminal vesicle glands, peritoneum, vascular and nerve bundles and other tissues and organs as well as distant metastases, surgery can be carried out after auxiliary endocrine therapy, and auxiliary drug therapy or radiotherapy can be given after surgery, and at this time, most of the patients’ sexual organ functions cannot be preserved. The same disease, the patient’s physical condition is different, different stages of the disease, the treatment method is different, should be under the guidance of the doctor for treatment.
