If a mass is found in the urethra, the first thing to consider is a wart, a tumor or a scar caused by an injury to the urethra. In this case, it is best to be able to do a cystoscopy and take a biopsy for pathological examination to clarify the diagnosis. If it is a tumor or warts of the urethra, it needs to be removed surgically as soon as possible. If it is a scar inside the urethra, this condition often patients have a clear history of trauma and it can also cause symptoms such as urethral stricture, thinning of urine flow and dripping urine. For this condition, urethral dilatation surgery or urethral scar removal is recommended.
