Why Open Surgery Should not be done for Bladder Tumors?

Bladder tumors are very common. Most of them can be cured easily if identified early. Usually the superficial tumors of the bladder are treated with transurethral resection. They are not resected opening the bladder trans-abdominally. It is because there is a very high risk of tumor deposition along the tract if surgery is done trans-abdomonally.
