The common diseases that cause pelvic pain in adult men are prostatitis and prostate cancer.
Acute and chronic bacterial prostatitis are often caused by bacterial infections. Acute prostatitis has a rapid onset and is characterized by chills, fever, suprapubic pain and abnormal urination; chronic bacterial prostatitis is characterized by pain and abnormal urination.
Prostate cancer is highly prevalent in elderly men, and there is no obvious clinical symptom in the early stage of the disease, but as the tumor invades the surrounding tissues such as seminal vesicles, vas deferens and ureter, it will show back pain, testicular pain, ejaculation pain and difficulty in urination. If the tumor metastasizes to bone, bone pain will appear, and metastasis to lymph nodes will cause swelling of lymph nodes.
In addition, pelvic pain in men caused by trauma to pelvic fracture and bladder lesion is easier to distinguish. Pelvic fracture has obvious history of trauma, and bladder lesion is often accompanied by symptoms such as urinary frequency, urinary urgency, urinary pain and hematuria.
