Background
Bladder cancer is currently one of the most common clinical tumors in urology. The stage of bladder cancer refers to the depth of tumor infiltration and metastasis, and is one of the most important indicators for determining bladder tumor prognosis.
Transurethral cystectomy (TURBT) is the primary surgical treatment for non-muscle invasive bladder cancer. TURBT serves two purposes: firstly, all macroscopic tumors are excised, and secondly, tissues are excised for pathological grading and staging. Transurethral cystotomy (TURBT) is also one of the most common procedures in urology. TURBT of conventional bladder tumors typically minced the tumor and flushed through the working channel with a syringe or Ellik extractor. It clearly violates the rationale of oncology, with tumor fragmentation leading to two major drawbacks: first, pathological examination of the specimen is severely compromised and the tumor margins cannot be assessed correctly, resulting in infiltration of connective or muscle tissue under the urothelium that may be underestimated or even missed. Second, the implantation of urothelial cancer cells occurs readily after tumor resection and fragmentation, which may lead to recurrence. Thus, holistic enucleation techniques for bladder cancer are gaining favor to more clinicians.
