Urethroplasty is a surgical procedure that is performed to reconstruct or repair the urethra, the tube that carries urine from the bladder to the outside of the body. Urethroplasty may be necessary if the urethra has become narrowed or obstructed due to injury, infection, or previous surgery.
Urethroplasty is typically performed under general anesthesia, and the exact procedure will depend on the location and severity of the urethral obstruction. In some cases, the surgeon may need to use tissue from another part of the body, such as the cheek or the lining of the mouth, to reconstruct the urethra. This is known as a graft. In other cases, the surgeon may be able to simply widen the urethra using a technique called dilation.
