Urinary retention is the impossibility of emptying the bladder. With chronic urinary retention, if you want to urinate, you may have a problem with adequate fullness of the jet or emptying the bladder. Also, you can feel frequent urge to urinate or feel incomplete emptying of the bladder. In this case, one way or another, urination persists and the outflow of urine occurs.
In the case of acute urinary retention, you can not urinate at all, even though the bladder is full. The presence of chronic urinary retention in addition to discomfort, also leads to serious impairment on the part of the whole organism.
Urinary retention can be caused by mechanical impairment, the so-called. obstruction of the urinary tract or functional disorders at the level of nerve fibers. Lack of normal activity on the part of the nervous system leads to the fact that the muscles of the sphincter work inadequately (relaxed or tense), which is manifested by incontinence or a delay in urine, and disorders of the nervous system can lead to no urination or normal contraction of the bladder.
In the event that chronic urinary retention is caused by prostate adenoma, drugs that relax the sphincter of the bladder, namely alpha 1 adrenoblockers, are used.
