How Does Chronic Prostatitis Cause Urinary Issues?

Date:2020-04-21 click:
The mechanism of urinary issues caused by chronic prostatitis is complex and unclear, and a single mechanism can not explain all kinds of manifestations satisfactorily.
 

 
1. Functional posterior urethral obstruction
 
It is the most commonly used mechanism. Other scholars also think that the autonomic contraction of the external sphincter of the urethra is the cause of this kind of obstruction. This autonomic contraction is due to the dysfunction of the sympathetic nerve in the pelvic cavity, which can lead to the spasm of the external sphincter and the stricture of the urethra.
 
Obstruction can increase the internal bladder pressure and smooth muscle hypertrophy, and eventually lead to the decrease of the density of nerves related to the smooth muscle innervating the bladder and urethra, so as to be in a state of denervation, which can induce the detrusor to contract without inhibition and form an unstable bladder and lead to urinary issues.
 
2. Local stimulation factors of prostate
 
The local prostate is stimulated by various inflammatory or noninflammatory factors, resulting in cell and interstitial edema, narrowing of the prostate urethra, increasing of pressure, resulting in urine flowing back into the prostatic duct and peritubular tissue, resulting in "chemical prostatitis," forming continuous stimulation, and recurrent dysuria.
 
Clemens and others think that local stimulation of the prostate may cause habitual contraction and spasm of pelvic floor muscles, which may lead to tension myalgia of the posterior pelvic floor through some mechanism, and thus lead to urinary issues.
