Urine is not fluent very pressure may be urinary system inflammation, urinary stones, prostate hyperplasia and prostate tumors and other factors. 1. urinary system inflammation: mostly seen in young patients, including prostatitis, cystitis and other causes of urinary system mucosal hemorrhage and edema, there may be urethral stenosis. Another inflammation may stimulate the prostate gland, oppression of the urethra, when urinating to produce a sense of pressure. 2. urinary stones: including urethral stones, bladder stones, kidney stones, etc., when the stone is relatively large, it may lead to obstruction of the urinary system, resulting in urinary incontinence, urinary pressure symptoms. 3. Prostatic hyperplasia: mostly occurring in the elderly, prostatic hyperplasia patients with enlarged glands, is likely to compress the urethra, resulting in poor urination and a sense of pressure. 4. Prostate tumor: some prostate tumors may also affect urination, which may cause similar symptoms. To summarize, the cause of dysuria with pressure is complicated, we suggest patients to go to the hospital to cooperate with doctors to do further examination, according to the results of the examination can diagnose the cause and do the treatment.
