Because men and women are different, the anatomical organs underneath the male and female urethra are different. The male urethral opening is located in the middle of the head of the penis in the form of a slit. Below the urethral opening is the prepuce tie, when the patient performs circumcision, there can be edema of the prepuce tie, but don’t be nervous, about 1-2 weeks after the edema of the prepuce tie will mostly be relieved or disappeared, below the urethral opening of the female is the vagina. When the patient presents with urethral caruncle, the swelling is visible at the urethral opening, usually without pain, but it should also be distinguished from urethral acromegaly. If the patient appears urethral swelling need to go to a specialist hospital, except warts or urethral tumors.
