Columnar hydrocapsule dilatation is mainly used for the treatment of patients with prostate enlargement, and it is recommended to visit the Department of Urology of a tertiary public hospital for treatment. Prostatic hyperplasia is a male-specific condition that mainly occurs in men over 50 years of age. Patients with mild cases can be treated conservatively with medication, while patients with severe cases need surgical treatment. Columnar hydrocapsule dilatation is a minimally invasive surgical procedure, which is performed by dilating the urethra, prompting the expansion of prostate tissues, thus improving urethral obstruction and improving patients’ clinical symptoms. It is recommended to go to the urology department of a tertiary public hospital, on the one hand, tertiary hospital doctors have more experience. As the operation requires the operation of instruments for urethral dilatation and prostate tissue expansion, the operation of surgical instruments is more skillful and experienced than that of doctors in other levels of hospitals, so the operation is safer and more effective. On the other hand, tertiary hospitals have complete medical facilities, which can improve the safety of the operation, and the patient’s surgical results are also better. At the same time, the patient’s post-operative review, for the emergence of abnormalities, can also be better dealt with.
