TURBT Training Revolution: A New Model for Bladder Tumor Resection
"Discover how a novel porcine training model is transforming the way urologists learn transurethral resection of bladder tumor, improving skills and patient outcomes."
Transurethral resection of bladder tumor (TURBT) is a cornerstone procedure in urology, essential for diagnosing and treating bladder cancer. It requires precision and skill to ensure complete tumor removal while preserving healthy tissue. Traditional training often relies on real-patient scenarios, which can be challenging for novice surgeons. The need for effective and accessible training models has never been greater.
A recent study published in the World Journal of Urology introduces a promising solution: a newly developed porcine bladder training model for TURBT. This innovative model aims to bridge the gap between theoretical knowledge and practical application, offering a safe and controlled environment for urologists to hone their skills in both piecemeal and en bloc resection techniques.
This article explores the development, validation, and potential impact of this novel training model. We'll delve into how it's constructed, the methods used to assess its effectiveness, and why it could revolutionize TURBT training, ultimately leading to improved patient outcomes and a higher standard of care.
TURBT’s Clinical Role
TURBT is the initial therapeutic intervention for bladder cancer and one of the most frequently performed endoscopic urological procedures. A 2023 systematic review likewise describes it as one of the most common everyday urological procedures, requiring skills developed through training and experience. The SEER Training module provides foundational information on bladder cancer, including statistics, risk factors, staging, and general treatment, but the supplied description does not give specific incidence figures.
A Demanding Core Procedure
TURBT is a fundamental procedure for diagnosing and treating bladder cancer, and it remains a common operation for residents and early-career urologists. The supplied systematic-review description notes that the procedure demands skills acquired through training and experience. A 2021 review emphasizes the importance and challenges of TURBT, advocating awareness of new resection techniques, a conceptual-systematic approach, and expanded training opportunities. Standardizing TURBT is presented as important for optimizing outcomes and reproducing results, with technologies such as blue-light cystoscopy and MRI among approaches discussed.
A Century-Old Foundation
TURBT has been a cornerstone of non-muscle-invasive bladder cancer management since the mid-20th century, according to a 2026 historical overview. A separate 2019 source reports that the first resectoscope was introduced more than a century ago and identifies TURBT as the gold standard for diagnosing and treating NMIBC. A 2017 history chapter traces TURBT’s evolution as one of urology’s early minimally invasive procedures and describes it as a focal, targeted operation performed through the urethra that is repeatable.
The Porcine Model: A Hands-On Approach to TURBT Training
The Asian Urological Surgery Training & Education Group (AUSTEG) recognized the critical need for improved TURBT training and developed a low-cost, easy-to-build model using ex vivo porcine bladders. This model provides a realistic simulation of the surgical environment, allowing trainees to practice and refine their skills without the risks associated with live surgery.
- Creating the 'Tumors': Bladder mucosa is tied with sutures to mimic bladder tumors of varying sizes and locations.
- Setting Up the Surgical Field: An anterior cystostomy is created in the porcine bladder, which is then everted to allow for the creation of the artificial 'tumors'. The bladder is reverted and placed in a training box.
- Simulating Resection: Resectoscope inserted via the urethra allows trainees to perform piecemeal and en bloc resections.
- Visual Feedback: The bladder is wrapped in a colored cloth to provide visual cues when the bladder wall becomes thin during resection.
Porcine Models and ERBT Practice
A systematic review reports that the Asian Urological Surgery Training and Education Group developed a porcine model for TURBT. A comprehensive review also identifies that group’s porcine training model as developed and validated. In a prospective learning-curve analysis using an ex vivo porcine model for en-bloc resection of bladder tumor (ERBT), the authors recommend at least 16 practice procedures for urologists with fewer than 100 TURBTs of experience and at least 13 for those with 100 or more, before progressing to live-animal training or supervised clinical practice.
Training Gains and Persistent Barriers
A national simulator-training study assessed recorded TURBT procedures before and after training using two blinded video raters and the Objective Structured Assessment for Transurethral Resection of Bladder Tumours Skills (OSATURBS) tool; the final procedure was performed within 30 days of simulator training. Its report describes improved operating-theatre performance by novice surgeons after proficiency-based virtual-reality training, while noting no significant effect on performance in another assessed area. Separately, a 2020 quality-performance report says high-quality TURBT remains elusive because of bladder shape, instrument limitations, perforation concerns, and a lack of specific, continued training.
The Future of TURBT Training
The porcine TURBT training model represents a significant step forward in surgical education, offering a cost-effective, accessible, and validated tool for urologists to enhance their skills. By providing a realistic simulation environment, this model empowers trainees to master TURBT techniques, potentially leading to improved patient outcomes and a higher standard of care in bladder cancer treatment.
Imaging and Robotic Directions
White-light cystoscopy (WLC) is used during TURBT for diagnosis, tumor removal, and local staging of non-muscle-invasive bladder cancer, but the supplied image-guidance source says WLC has significant shortcomings in tumor detection that affect recurrence and progression. A 2026 AUA/SUO guideline update adds 40 statements on risk stratification for NMIBC; its source reports that NMIBC accounts for approximately 80% of an estimated 84,530 new U.S. bladder cancer cases in 2026. At AUA 2026, a presentation on robotic-assisted transurethral surgery challenged the traditional resection paradigm and proposed it as a potential next step in en-bloc TURBT and minimally invasive bladder cancer surgery. A separate article describes a new porcine training model as a potential way to improve TURBT training and surgeon skill.
Expanding Training Opportunities
TURBT remains a central procedure for bladder cancer diagnosis and treatment, but urologists need to understand its importance as well as its challenges. A review calls for adoption of new resection techniques and a conceptual-systematic approach. It also argues that training opportunities should be expanded to improve patient outcomes.
Simulator Training in Practice
In a national implementation study, novices’ TURBT performance in the operating theatre improved after they completed a proficiency-based training programme on a virtual-reality simulator. The study’s source snippet also reports that simulator training had no significant effect on performance in an assessed area, indicating that the reported benefits were not uniform across all outcomes. Separately, a real-world cohort study examined whether MRI performed after TURBT could predict residual tumor and muscle-invasive bladder cancer in patients who subsequently underwent repeat TURBT or cystectomy.
While this model shows great promise, the researchers emphasize the importance of future studies to evaluate its predictive validity and assess the long-term impact on surgical performance. AUSTEG remains dedicated to surgical education and plans to continue providing high-quality training opportunities for urologists in Asia and beyond.
As TURBT techniques continue to evolve, the integration of innovative training models like the porcine bladder will be crucial in ensuring that urologists are well-equipped to provide the best possible care for their patients. Ultimately, this commitment to education will translate into improved outcomes and a better quality of life for individuals affected by bladder cancer.
