Irrigation. Cancer cells can spill during surgery and this can cause cancer to return ("recur"). Some surgeons believe that "irrigating" could help stop spilling of cancer cells. "Irrigating" means washing the surgical area with sterile water and sucking the water back up through a tube. As a result, surgeons vary as to how they irrigate. In this study, we will examine irrigation of the urethra. This is the part of the body that carries urine from the bladder to the penis.
