[Superficial bladder cancer: Transurethral resection and instillation therapy].

Bladder cancer is the fifth most common tumor in men with the incidence of bladder tumors continuing to rise in industrialized and developed countries. Because 80% of all bladder tumors grow on the surface, endoscopic transurethral resection (TUR-B) can be used for complete removal. Due to continuous technical developments and improvements of endoscopic equipment, video imaging and bipolar resection (TUR-IS) offers a high level of safety. Despite optimal equipment, intra- and postoperative complications in transurethral electrosurgery of bladder tumors may occur.
