Management of surface vesical tumours using laser photocoagulation has proven to be a safe and effective method. The technique can be performed under anaesthetic sedation and in the outpatient clinic environment thus allowing a considerable cost saving and the reduction of hospital's waiting lists. Throughout 1990, 47 patients with relapsing vesical tumours were treated in 55 sessions. Most cases were performed on ambulatory patients with a low complications rate and an estimated saving of 18,326,400 pesetas as compared to transurethral resection.
