The main clinical manifestations of benign prostatic hyperplasia

(1) the main symptoms: aggravated sexual dysuria, If the frequency (for the symptoms first appeared), due to prostatic hyperplasia caused voiding resistance increased, the bladder detrusor contraction to be excessive urination to complete the process, leading to the detrusor compensatory hypertrophy, bladder triangle for the most bladder sensitive region, compensatory hypertrophy is the site of the earliest, have very small amounts of urine can stimulate the triangle arousing urine Italy, and during the day because of distractions patients, urinary Italy flu threshold increased, it can be at night frequency even more remarkable. Other slow start may also be associated with urination, urinary lines are weak or interrupted urine, such as drip Lek.
Even when excessive bladder detrusor contraction can not completely emptying urine sometimes arise residual urine, when the bladder is already in a decompensated state, does a cold, drinking, and forbearance from urine or other reasons sympathetic excited, that is, can acute urinary retention. A small number of patients not obvious symptoms of bladder stimulation, but residual urine volume is great, the effective capacity of the bladder to reduce, if continue to develop, there will be the filling of urinary incontinence (intravesical pressure from the steady increase that exceeded the urethral closure pressure causing urine outflow ).
(2) Other symptoms: benign prostatic hyperplasia hematuria is a common symptom may be bladder contraction of the mucous membrane covering the prostate broken capillaries caused mostly a transient, but also a result of the merger caused infection or bladder stones.
Residual urine is a good medium for bacterial growth, coupled with a decompensated bladder mucosa defense functional impairment, so prone to cause urinary tract infections, urinary urgency visible, or even urge incontinence.
Renal dysfunction is caused benign prostatic hyperplasia lower urinary tract obstruction and long-term results of treatment are not reasonable, there will be anorexia, anemia, high blood pressure, consciousness retardation, lethargy and coma.
Because bladder outlet obstruction, there will be the bladder the lower abdominal mass or hydronephrosis caused by the abdominal mass. Long-term increase in abdominal pressure will eventually voiding cause hemorrhoids, and hernia formation.
