Prostate enlargement is a common disease in older men that often affects their lives and work. The common causes of prostate enlargement are mainly advanced age and high levels of androgens in the body. Prostate enlargement often causes a series of symptoms that endanger the health of patients, mainly including frequent urination, urgent urination, painful urination, hematuria, and severe prostate enlargement can cause hydronephrosis and kidney function damage. The reason for this is that the enlarged gland irritates the mucous membrane of the urinary tract, and the patient urinates more often, but the amount of urine each time is very small. The reason for this is because of the obstruction of the urinary tract caused by the enlarged gland; if there is a combination of bladder stones or urinary tract infections, painful urination often occurs. The hematuria is also one of the common symptoms of prostate enlargement, which generally occurs in larger enlarged patients. The enlarged gland ruptures the small blood vessels on the mucosa of the prostate urethra causing bleeding, and severe bleeding causes bright red urine and long-term bleeding, which can cause symptoms such as anemia. Patients in this situation often need timely indwelling urinary catheters to drain urine and relieve the symptoms of urinary retention caused by lower urinary tract obstruction.
