Warts in the urethra actually refer to the occurrence of warts in the urethra, which are common epidermal benign growths caused by human papilloma virus infection. Warts in the urethra do not appear in particularly deep areas, but usually at the opening of the urethra. In the early stages of warts in the urethra, the patient may not feel any symptoms, but as the warts grow, you may notice a significant change in the line or direction of the urine flow when you urinate. As the warts continue to grow, there may be significant urinary frequency, urgency and pain. The warts themselves are fragile and may bleed significantly if you are not careful. As the warts continue to grow, there may also be a significant foreign body sensation.
