Analysis of Endourological Treatment Techniques of Urinary Bladder Tumors

Abstract

Transurethral resection is very important not only for diagnosis and treatment of NMIBC, but also for its management. The application field of transurethral resection includes establishing histological diagnosis, determination of prognostic factors including the tumor stage, complete resection of all detected tumors of urinary bladder. Transurethral resection of bladder tumor (TURBT) is the standard technique for the diagnosis and treatment of non-muscle invasive bladder cancer. This method has also some limitations. One of the limitations is the insufficient assessment of the resection depth. It leads to the necessity of intravesical tumor fragmentation, but its disadvantage is that it limits the histopathological evaluation. In order to improve the treatment outcome for patients with non-muscular invasive bladder tumors, several new techniques such as En-bloc resection were proposed.
