The common treatment methods for prostate cancer and prostate enlargement: 1. Prostate cancer: Patients with prostate cancer are mostly older and have more accompanying lesions, so the treatment methods should be considered comprehensively. In early stage cases, surgical resection is preferred for those with good general condition. In middle and late stage cases, those who have more concomitant symptoms and cannot be operated or are unwilling to be operated, can consider trans-perineal puncture argon helium ultra-low temperature freezing, transurethral electrodesection of the prostate, radioactive particle placement, bilateral testicular removal (palliative), etc., among which argon helium ultra-low temperature freezing is currently preferred abroad. Both should be considered as an adjunct to the necessary medication chemotherapy, radiotherapy, endocrine therapy and other medical measures to improve the efficacy and quality of life of the patient. 2. Prostatic hyperplasia: Prostatic hyperplasia can be divided into three different degrees: mild, moderate, and severe, and those with mild and moderate clinical symptoms are relatively mild and can be treated conservatively without treatment or oral medication. Severe hyperplasia requires active intervention with appropriate surgical measures to relieve clinical symptoms. The most common methods are minimally invasive surgery and mega-invasive surgery: minimally invasive: such as perineal puncture argon helium ultra-low temperature freezing, transurethral resection of the prostate, etc. The most invasive methods are: minimally invasive: such as trans-pubic or trans-perineal prostatectomy, bilateral testicular removal, etc. Interventional treatment of prostate cancer and prostate hyperplasia: Interventional techniques have been widely used in the treatment of prostate hyperplasia and prostate cancer in recent years, mainly including the following: 1. Trans-perineal prostate puncture with argon helium cryopreservation: the application of ultra-low temperature technology to freeze and re-temperature ablation of the gland. 2. 2. radioactive particle placement: radioactive particles are placed inside the gland to provide internal irradiation, mainly for prostate cancer. 3. Transcatheter arterial embolization and infusion chemotherapy: mainly used for prostate cancer, embolization can also quickly control the symptoms of hematuria. Which patients are suitable for argon helium cryotherapy? Patients with moderate or severe prostate hyperplasia, early stage prostate cancer who are unwilling to undergo surgery, middle and late stage cases, and patients with more accompanying symptoms who cannot undergo surgery can be considered. What is the effect of argon helium cryotherapy on prostate enlargement and prostate cancer? It is less traumatic and has fewer side effects. It can quickly ablate the prostate hyperplasia and tumor and relieve the symptoms of urinary tract obstruction.
