A transurethral resection of bladder tumor (TURBT) or a transurethral resection (TUR) is often used to find out if someone has bladder cancer and, if so, whether the cancer has spread into (invaded) the muscle layer of the bladder wall.
TURBT is also the most common treatment for early-stage or superficial (non-muscle invasive) bladder cancers. Most patients have superficial cancer when they’re first diagnosed, so this is usually their first treatment.
Sometimes, a second, more extensive TURBT is done to better ensure that all the cancer has been removed. The goal is to take out the cancer cells and nearby tissues down to the muscle layer of the bladder wall.
