The surgical treatment of prostate enlargement has been developed for more than 100 years, but the principle of surgery has not changed with the passage of time, which is to remove as much enlarged prostate tissue as possible through surgery. We know that the application of 5-alpha reductase inhibitors treats prostate enlargement by controlling the growth and reducing the size of the prostate, but it often takes longer to get results from taking medication, while surgery to visually remove the prostate can quickly produce therapeutic results. This shows that if the prostate enlargement is serious and not treated in time is more harmful, surgery is often the best option. The following these situations doctors will recommend patients to take surgical treatment. 1, repeated hematuria due to prostate enlargement. 2. Repeated acute urinary retention caused by prostate enlargement. 3. Recurrent urinary tract infections caused by prostatic hyperplasia. 4.Kidney and ureteral effusion and even renal function damage caused by prostatic hyperplasia. 5. Bladder stones caused by prostatic hyperplasia. 6. Prostatic hyperplasia with mainly middle lobe hyperplasia. 7. Patients who take medication for a long time, if the treatment effect is not satisfactory and the clinical symptoms are serious, the doctor will also recommend the patient to perform surgery.
