Calcification of the prostate alone usually does not cause abdominal distension, but if it is accompanied by severe prostatic hyperplasia or prostatitis, it may lead to abdominal distension. Calcification of the prostate is the deposition of calcium salts in the prostate tissue, which may be formed naturally during the physiological process, or it may be related to chronic prostatitis. Usually, there are no obvious clinical signs and symptoms when there is only calcification of the prostate. If it is accompanied by prostatitis, there may be soreness and pain near the perineum, abnormal urination and other manifestations. If people with prostate calcification also have prostate hyperplasia, there will be no obvious symptoms in the early stage, when the size of the prostate gland gradually increase can lead to serious difficulty in urination, resulting in urinary retention, at this time, there will be abdominal distension and pain and other manifestations. Therefore, if people with prostate calcification experience abdominal distension, difficulty urinating, urinary urgency and frequency, they need to consult a doctor and undergo relevant examinations to determine whether there is prostatitis or prostate hyperplasia.
