Bladder cancer treatment is entering a new era. From gene therapy and bladder preservation to AI-assisted diagnostics and the challenge of detecting “hidden” CIS, Dr. Ravi Chauhan, MD, FACS breaks down the technologies and clinical decisions reshaping urology in 2026.
Dr. Ravi Chauhan, MD, FACS ( https://conradpearson.com/our-specialists/ravi-d-chauhan-m-d-facs/ ) is a board-certified urologist, fellowship-trained uro-oncology specialist, and one of the leading voices in advanced kidney and bladder cancer care in the Mid-South.
Born and raised in Memphis, Tennessee, Dr. Chauhan graduated Cum Laude from Rhodes College with a degree in molecular biology before earning his M.D. and completing both his general surgery internship and urologic surgery residency at The University of Tennessee Health Science Center. He joined the Conrad Pearson Clinic in 2005 and has since become a recognized leader in the treatment of advanced bladder and kidney cancers, with numerous publications and presentations to his name.
Dr. Chauhan’s path into medicine was deeply personal. Inspired by watching his father practice medicine and witnessing the profound impact physicians can have on patients and families, he developed a philosophy centered on treating every patient with the same compassion, respect, and attention he would want for his own family.
In addition to his expertise in surgical urology and uro-oncology, Dr. Chauhan has become increasingly focused on one of the biggest challenges in modern bladder cancer management: identifying and treating high-risk non–muscle invasive bladder cancer - or NMIBC, particularly carcinoma in situ - or CIS , which can often be difficult to detect in routine clinical practice.
Today, we’ll discuss the evolving diagnostic landscape for CIS, why missed or under-recognized disease can significantly impact treatment decisions, and the growing importance of collaboration between urologists and pathologists. We’ll also explore how community urologists are navigating these rapidly evolving standards of care, the future of precision bladder cancer management, and what it means for patients facing this disease.
We’ll also discuss bladder-sparing approaches, including Adstiladrin® (nadofaragene firadenovec-vncg), an intravesical gene therapy for adults with high-risk Bacillus Calmette-Guerin (BCG)-unresponsive NMIBC with CIS, with or without papillary ( https://www.adstiladrin.com/ ).
ADSTILADRIN should not be used in patients with hypersensitivity to interferon alfa or its components, and individuals who are immunosuppressed or immune-deficient should not handle or receive the therapy. Delaying cystectomy in patients with BCG-unresponsive CIS could lead to development of muscle invasive or metastatic bladder cancer, which can be lethal. If patients with CIS do not have a complete response to treatment after 3 months or if CIS recurs, consider cystectomy.
The most common adverse reactions include urinary discharge, fatigue, bladder spasm, urgency to urinate, and blood in urine. Patients should consult their healthcare provider regarding all medications and report any side effects.
