Attaining a high-quality TURBT is not always guaranteed due to various factors. En-bloc resection of bladder tumors (ERBT) holds promise to be a primary technique for removing bladder tumors in most non-muscle invasive bladder cancers. However, so far, no conclusive evidence indicates the superiority of any specific energy source used for ERBT. While laser energy can prevent the activation of obturator nerve reflex during ERBT, it poses challenges such as thermal injury and imprecise controllability. Needle-shaped electrodes offer high-level precision and controllability, without causing tissue deterioration or vaporization. The primary limitation of ERBT at present is the extraction/harvesting of large en-bloc specimens. Effective tools have been developed to overcome this limitation. Enhanced cystoscopy improves the detection of flat and small bladder tumors, allowing for better removal of cancerous tissues and significantly reducing recurrence rates. Advances in medical technology have brought forth a multitude of strategies to address the shortcomings of traditional TURBT. Appliances with large operating channel provide a platform for conducting laparoscopic procedures within the context of pneumocystoscopy, facilitating the execution of super TURBT and conferring comparable advantages to en-bloc resection. Moreover, the utilization of pneumocystoscopy enables the safe and effective performance of transurethral partial cystectomy for localized muscle-invasive bladder cancer. Novel techniques significantly improve the precision of the transurethral surgery and lower the risk of complications.  \nKeywords: transurethral resection of bladder tumor, bladder cancer, super TURBT, partial cystectomy  \nBladder cancer represents one of the most prevalent cancers across the globe. Approximately, 75% of the cases fall into the category of non-muscle-invasive bladder cancer (NMIBC), which encompasses Ta, T1, and Tis (tumor in situ) [1] . The standard treatment for NMIBC is transurethral resection of bladder tumors (TURBT) plus adjuvant intravesical chemotherapy [2] .  \nTURBT, which employs a wire loop, is regarded as the cornerstone and gold standard for staging and treating NMIBC since the 1910s [3]. Nevertheless, the piecemeal resection, the potential scattering of tumor cells, and the absence of detrusor muscle in the resected specimen are believed to be drawbacks of the conventional TURBT [4,5]. This resection technique isnot inline with the fundamental principles of oncological surgery, i.e., efficient diagnosis and treatment of bladder cancer. In recent years, advances in medical technologies, including surgical techniques  \nand instruments, micro or small tumor imaging, hav","cbCaigXSzGPenp8l","https://ap.wps.com/l/cbCaigXSzGPenp8l","pdf",834762,"English","# Abstract\n# Introduction\n## Background on NMIBC and TURBT\n# En-bloc Resection\n## ERBT provides high-quality specimen","[{\"question\":\"What are TURBT and ERBT used for in bladder cancer management?\",\"answer\":\"TURBT is used for both diagnostic staging and therapeutic resection.
