Holmium Laser En-Bloc Resection Versus Conventional Transurethral Resection of Bladder Tumors for Treatment of Non-muscle- Invasive Bladder Cancer

This study is a prospective randomized controlled trial comparing holmium laser en-bloc resection of bladder tumor (HoLERBT) with conventional transurethral resection of bladder tumor (cTURBT) in patients with suspected non-muscle-invasive bladder cancer (NMIBC). A total of 100 patients will be randomly assigned in a 1:1 ratio to undergo either HoLERBT or cTURBT. The primary outcome is the quality of the pathological specimen, assessed by the presence of detrusor muscle. Secondary outcomes include perioperative complications, operative time, obturator nerve reflex, bladder perforation, positive surgical margins, persistent disease at second-look TURBT, and recurrence rates at 3 and 12 months, as well as recurrence-free survival. This study aims to evaluate whether HoLERBT provides superior resection quality and improved clinical outcomes compared to conventional TURBT.

The Effect of Video Calls With Family Members During Operating Room Waiting on Stress, Anxiety, and Surgical Fear in Patients Undergoing Transurethral Resection of Bladder Tumor

This study aims to investigate the effect of video calls with family members during the preoperative waiting period in the operating room on stress, anxiety, and surgical fear in patients undergoing transurethral resection of bladder tumor (TURBT). Bladder cancer is a common urological malignancy, and psychological problems are frequently observed in the preoperative period. The absence of family support in the operating room may increase anxiety and fear, triggering physiological stress responses and raising the risk of complications. This multicenter randomized controlled trial will be conducted between September 2025 and March 2027 at Bitlis State Hospital and Tatvan State Hospital. The study sample will include 128 eligible patients, randomly assigned to intervention and control groups. Patients in the intervention group will have a video call with a designated family member in the operating room, while control group patients will receive routine care. Data will be collected using the Descriptive Information Form, the Surgical Fear Questionnaire, and the Visual Analogue Scale; stress levels will be assessed through serum cortisol and glucose values. Measurements will be taken at three time points: preoperatively (T0), immediately before anesthesia (T1), and on the first postoperative day (T2). The study is expected to demonstrate that maintaining family support through video calls in the preoperative period reduces anxiety, fear, and stress, thereby improving surgical outcomes and contributing to the development of family-centered care practices.
