Purpose Of Review: Transurethral resection of bladder tumor (TURBT) remains the basis of bladder tumor diagnosis and an effective means of treating nonmuscle invasive bladder cancer (NMIBC). There are several limitations to this procedure: TURBT may cause free floating of malignant cells in the bladder and as a result re-implantation and early recurrence. Also, it does not allow the pathologist to define the correct spatial orientation of the specimen. The development of en bloc resection of bladder tumor (ERBT) has helped overcome the abovementioned key disadvantages of TURBT. However, many urologists doubt whether this approach is feasible for treating larger tumors.
Recent Findings: In this review, it is shown that ERBT of large bladder tumor (>3 cm) is in fact a feasible and well tolerated method. Although there is a lack of comparative data proving its advantages over TURBT, en bloc in large tumor seems to result in better local cancer control (due to higher prevalence of detrusor specimen, lower need for re-TURBT), lower rate of relapse outside the resection area (due to lower risk of tumor cells circulation), and higher quality of pathology specimen.
Summary: Despite the skepticism of some surgeons, potential difficulties caused by larger tumor size may be overcome easily, and most agree that tumor size should not limit the implementation of the method in their daily practice.

Gemcitabine (GEM) is a first line chemotherapy drug for bladder cancer (BCa). GEM's lack of specificity has led to disadvantages, resulting in low efficiency, especially when combined with the targeted treatment of BCa stem cells (CSCs), which is considered the cause of BCa recurrence and progression. To enhance the anti-cancer effect and reduce the side effects of GEM targeting of BCa cells/CSCs, an aptamer drug conjugate (ApDC) targeted delivery system was used to improve the efficiency of GEM in BCa therapy using EpCAM aptamer-GEM conjugates based on the epithelial cell adhesion molecule (EpCAM), which is highly expressed on the cell membrane of BCa cells/CSCs.

Objectives: To evaluate the role of neoadjuvant chemotherapy in the final treatment plan and its impact on survival in bladder cancer patients who were diagnosed with variant histology in the radical cystectomy specimen and whose diagnostic accuracy was achieved with the previous transurethral resection of the bladder specimen.
Methods: In this retrospective multicenter study, data from 221 patients across 9 centers were analyzed between January 2012 and January 2022. The primary endpoint was overall, cancer-specific, recurrence-free, and metastasis-free survival rates among patients with and without neoadjuvant chemotherapy, and the secondary endpoint was to identify independent predictors of survival.

Objectives: To explore the experience of tumor control technique in robot-assisted laparoscopic bladder diverticulectomy (RALBD) in the treatment of bladder diverticulum tumor, intraoperative tumor control and postoperative comprehensive treatment.
Patients And Methods: We treated three male patients with bladder diverticulum tumors. Case 1 involved a 63-year-old with a 3.

Background: Bladder cancer (BC) is a malignant tumor. Methyltransferase-like 7B (MEETL7B) is a methyltransferase and its role in BC has not yet been revealed.
Method: Stable METTL7B knockdown or overexpression were achieved by lentiviral transduction in SW780 and TCCSUP cell lines.
