[Potential for improvement by new resection and imaging techniques in TUR-B]

Transurethral resection of bladder tumors (TURB) is the cornerstone in urological care of bladder cancer patients. Since the introduction of resectoscopes almost 100 years ago, little has changed in the basic resection technique. The further dissemination of the en-bloc resection (ERBT), which in contrast to fragmented removal preserves the tumor's integrity, might re-adjust the surgical landscape. Benefits attributed to ERBT are better histopathological judgment and higher detrusor muscle rate. In addition, trends for a lower rate of so-called "in-field" recurrences as well as a reduced complication rate have been described. However, randomised, controlled studies with appropriate case numbers and methodology are pending. Few innovations in improved endoscopic tumor diagnostics have been added in recent years. Worth mentioning is the multiparametric magnetic resonance imaging of the bladder, which is intended to improve the accuracy of local tumor propagation compared to conventional imaging alone, as well as techniques in the field of artificial intelligence. The intention of this article is to provide an up-to-date status on EBRT as well as the local diagnostics for urinary bladder tumors.
