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

Area of Science:

• Urology
• Oncology
• Surgical Innovation

Background:

• Transurethral resection of bladder tumors (TURB) has remained largely unchanged for nearly a century.
• En bloc resection (ERBT) preserves tumor integrity, contrasting with traditional fragmented removal.
• ERBT is associated with potential benefits like enhanced histopathological assessment and increased detrusor muscle yield.

Purpose of the Study:

• To provide an updated overview of en bloc resection techniques for bladder tumors.
• To review recent advancements in local diagnostic methods for urinary bladder tumors.

Main Methods:

• Review of current literature on en bloc resection (ERBT) and transurethral resection (TURB) for bladder tumors.
• Discussion of emerging diagnostic technologies, including multiparametric MRI and artificial intelligence.

Main Results:

• ERBT may lead to superior histopathological evaluation and a higher rate of adequate detrusor muscle in specimens.
• Preliminary data suggests ERBT might reduce in-field recurrence rates and complications.
• Innovations in local tumor diagnostics, such as multiparametric MRI, aim to improve staging accuracy.

Conclusions:

• En bloc resection (ERBT) presents a promising alternative to TURB for bladder tumors, with potential oncological and pathological advantages.
• While promising, robust randomized controlled trials are necessary to validate the benefits of ERBT.
• Advancements in imaging and AI are enhancing the diagnostic capabilities for bladder cancer.
