As a doctor, you should first take a careful medical history: whether the patient has diabetes or neurological pathology, because these pathologies can cause changes in bladder function, resulting in symptoms of dyspareunia. If the patient has a history of urinary tract injury, urethral stricture can also cause these symptoms. In a word, the possibility that these clinical symptoms are caused by other diseases should first be ruled out. The next step is to examine the size and texture of the prostate to further determine if these symptoms are caused by prostate enlargement. The actual size of the prostate can be measured by two methods: one is anal diagnosis; the anal diagnosis can initially feel the size and texture of the prostate, and whether there are nodules. If the texture is hard and the nodularity is more obvious, the possibility of prostate cancer is higher and prostate cancer needs to be further ruled out. The other method is the ultrasound examination, by measuring and calculating the size of the prostate. After a thorough medical history, physical examination and ancillary tests to determine the diagnosis a thorough evaluation of the patient is required to lay the foundation for the next treatment plan.
