Abstract
The early intravesical Instillation of mitomycin C (MMC) is accepted as safe adjuvant therapy after TURBT by non-muscle- invasive bladder cancer if there is no perforation. In our case we report a female patient undergoing resection of papillary recurrent tumor on the anterior bladder wall. In the early postoperative period had the patient no complaints regarding to Instillation of MMC. The clinical manifestation of the necrosis of the anterior bladder wall appeared after one week requiring a long extended unsuccessful conservative therapy in order to save the bladder. Finally we performed a radical cystectomy. This complication is reported by some authors in literature.
