Prostate hyperplasia is a common disease in older men, with a prevalence of about 50% over the age of 60 and 88% over the age of 80, and its incidence is on the rise as people’s life expectancy increases. Most patients with prostatic hyperplasia are old, frail and sickly. For patients with indications for surgery, minimally invasive intracavitary surgery is the preferred treatment. The Department of Urology of our hospital recently used 2 micron laser to treat an elderly patient with oversized prostate with the cooperation of the Department of Anesthesia and Surgery and the Cystoscopy Room to achieve satisfactory results, which are reported below. The patient was an 85-year-old retired cadre who was admitted to the hospital with acute urinary retention associated with prostatic hyperplasia, and the patient also had hypertension and coronary heart disease. The patient’s medical relationship is not in our hospital, but because of the good reputation of our 2 micron laser in the society, he requested to undergo laser prostatectomy at his own expense. After ultrasound examination, the patient’s prostate size was 7.8cm x 7.9cm x 8.0cm and the estimated prostate weight was about 270g, which is more than 20 times the normal prostate size. The prostate hyperplasia was mostly treated with open surgery, which is traumatic, bleeding and hard on the patient, and later prostate electrosurgery was gradually adopted, but it is prone to intraoperative and postoperative complications such as intraoperative and postoperative bleeding, prostate electrosurgery syndrome and its effect on the heart. The use of 2 micron laser for prostatic hyperplasia has the advantages of less trauma, less bleeding, and less impact on the heart, and is especially suitable for elderly and frail patients. At present, for prostates weighing more than 80g or more are called large prostates, and laser surgery on large prostates may have poor surgical results, and open surgery is mostly advocated. The patient is old, frail, and has a poor heart condition, and open surgery and electrodes are risky, so the patient and his family are reluctant. The patient’s body may not be able to withstand the operation, and if the patient’s heart condition is unexpected during the operation, the operation may be stopped at any time, on the other hand, the operator’s requirements are high, requiring the removal of more prostate tissue in the shortest possible time. On the other hand, the operator is required to remove as much prostate tissue as possible in as short a time as possible, otherwise there is a possibility that the patient may still have difficulty in urination after surgery. The operation is very invasive, and there is a possibility of a lot of bleeding during and after the operation, which requires satisfactory hemostasis. The operation was performed by Dr. Jia Yongzhong, deputy chief surgeon. The patient had frequent atrial premature beats, frequent ventricular premature beats and pathological Q waves immediately after admission to the operating room. The patient’s cardiac condition gradually improved after careful conditioning by Dr. Ning Xinyu, deputy chief of the Department of Anesthesiology. The operation was performed under television surveillance. During the operation, it was seen that the prostate was enlarged and the posterior urethra was severely elongated, and the entire posterior urethra was almost completely blocked by the prostate. Dr. Jia Yongzhong, deputy chief surgeon, used the 2-micron laser to remove the hyperplastic gland block by block, and the operation went smoothly and took about 1.5 hours. The operation took about 1.5 hours. There was little bleeding during the operation and the patient recovered well after the operation. The patient and his family were very happy and sent the urology department a banner when he was discharged from the hospital and said that he would refer more patients to our hospital for laser prostate surgery after discharge. Since 2006, the Department of Urology of our hospital has carried out 2 micron laser treatment for prostate hyperplasia in China, and later used 2 micron laser for the treatment of bladder tumor, urethral stricture, bladder neck fibrosis, ureteral stricture, kidney tumor resection, etc. More than one thousand surgeries have been carried out, and the operation time and number of surgeries are in the forefront in China, and 2 micron laser treatment has also become the characteristic project of our urology department. The 2-micron laser treatment has also become a specialty of our urology department, generating good economic and social benefits. The treatment of the oversized prostate in this case further demonstrates the level of 2-micron laser treatment for prostate hyperplasia in our hospital and expands the scope of indications for 2-micron laser treatment for prostate hyperplasia.
