With the improvement of instruments and equipment, TURP surgery has become the first choice for the treatment of prostate enlargement with the advantages of less trauma, postoperative recovery block and precise efficacy. The surgery can be considered for patients with recurrent urinary retention, combined bladder stones, filling incontinence, hydronephrosis, and poor results of drug therapy, while patients with severe systemic diseases, serious urinary tract infections, and complicated urethral strictures are contraindicated. Patients should be excluded from prostate cancer before surgery, if not, a prostate puncture biopsy should be performed. Patients with combined urinary tract infection should have their infection controlled before surgery. Urethral catheter should be left in place and the bladder should be continuously flushed after surgery. After surgery, the patient should keep the stool open and should not strain when defecating. Drink more water after removal of the urinary catheter. Patients often experience urinary incontinence after the catheter is removed again, but this phenomenon is temporary and transient, and the incidence of permanent urinary incontinence is very low. Some patients may develop epididymitis after surgery, so patients with fever and scrotal swelling and pain should be seen promptly about 2 weeks after surgery. At present, transurethral laser technology can also be used to treat prostate enlargement, because its high temperature can vaporize the tissue and can directly coagulate the blood vessels, which can reduce intraoperative bleeding and is more suitable for elderly patients.
