BackTable Urology

What do you do when metastatic urothelial cancer responds dramatically to systemic therapy? In this episode of BackTable Urology, Dr. Abhinav Khanna (Mayo Clinic) speaks with host Dr. Daniel Roberson about the growing question of consolidative surgery after enfortumab vedotin plus pembrolizumab. They discuss how EV-pembro has reshaped treatment expectations, why unexpected complete or near-complete responses are prompting tumor board debates about cystectomy, and how careful multidisciplinary decision-making guides which patients may be considered for surgery.

---

SYNPOSIS

The conversation reviews early outcomes showing high rates of pathologic downstaging and the possibility that many patients may avoid additional systemic therapy after surgery, while emphasizing this approach is not yet standard of care. Dr. Khanna highlights coordination with medical oncology, radiology, and pathology, postoperative considerations, and the potential future role of biomarkers such as ctDNA. Ultimately, the episode underscores the need for clinical trials and thoughtful patient selection as clinicians navigate integrating surgery into an evolving systemic therapy landscape.

Is transecting urethroplasty still the default, or is reconstructive urology moving beyond it? In this episode of BackTable Urology, Dr. Ben Breyer (University of California San Francisco) joins host Dr. George Koch (Ohio State University) to discuss evolving approaches in reconstructive urology with an emphasis on complex stricture cases.

---

SYNPOSIS

Throughout the conversation, Dr. Breyer reflects on his path into the subspecialty and breaks down the evolution of reconstructive practice, particularly the shift from anastomotic urethroplasty to non-transecting techniques. Dr. Breyer and Dr. Koch also discuss managing complex urethral strictures, including cases involving prior radiation and inflammatory conditions, while emphasizing thoughtful patient selection and surgical planning. Finally, they explore the current training landscape, challenges in patient access to subspecialty reconstructive care, and why patient-reported outcomes will play a central role in shaping future innovation in urethral reconstruction.

When is active surveillance the right choice for intermediate-risk prostate cancer patients? In this episode of BackTable Urology, Dr. Claire de la Calle, Assistant Professor of Urology at the University of Washington, joins Dr. Ruchika Talwar to unpack how active surveillance has evolved beyond low-risk disease and why select Grade Group 2 patients may be appropriate candidates now with thoughtful patient selection.

---

SYNPOSIS

The conversation explores emerging tools that can refine surveillance decisions, including PSA density, MRI findings, genomic classifiers, and the growing role of AI-assisted pathology. Dr. de la Calle emphasizes the importance of nuanced patient counseling, acknowledging anxiety and long-term risk while reinforcing that time on active surveillance can be a meaningful win when oncologic outcomes remain comparable to upfront treatment.

Is the era of cisplatin over, or are we simply becoming more precise about who benefits from it? As perioperative strategies in bladder cancer continue to evolve, emerging tools like circulating tumor DNA (ctDNA) are playing a bigger role in how clinicians assess recurrence risk and tailor treatment. In this episode of BackTable Tumor Board, host Alan Tan, medical oncologist at Vanderbilt-Ingram Cancer Center, is joined by bladder cancer experts Dr. Amanda Nizam and Dr. Brad McGregor to discuss recent advances in the diagnosis and treatment of urothelial carcinoma.

SYNPOSIS

The doctors examine the evolving management of muscle-invasive bladder cancer (MIBC), including the role of neoadjuvant and adjuvant therapies, the integration of immunotherapy, and the recent approval of enfortumab vedotin plus pembrolizumab. The discussion explores the rapidly changing perioperative landscape, the prognostic utility of ctDNA, and how biomarkers such as HER2 and FGFR are influencing treatment selection across disease states. They also address bladder preservation strategies, management of treatment-related toxicities, and the importance of multidisciplinary coordination. The episode concludes with a forward-looking discussion on emerging therapies and the potential to improve cure rates in bladder cancer.

In reconstructive urology, preventing infection often means prolonged antibiotic exposure, raising important questions about stewardship and long-term harm. In this episode of BackTable Urology, Joshua Sterling of Yale University joins host George Koch to examine how antibiotic stewardship and emerging insights into the urinary microbiome are reshaping infection management in reconstructive practice.

---

SYNPOSIS

The discussion centers on real-world clinical challenges, particularly in high-risk populations such as patients with neurogenic bladder, chronic catheterization, or prior reconstruction - groups in whom antibiotics are frequently used prophylactically or indefinitely. Drs. Sterling and Koch explore how well-intentioned prescribing patterns can contribute to resistance, dysbiosis, and recurrent infection, while often failing to address the underlying drivers of disease.

Rather than framing infection control solely around eradication, the conversation considers a shift toward modulation of the urinary microbiome, drawing on lessons from gastroenterology, infectious disease, and transplant medicine. The episode concludes by outlining how a more nuanced, multidisciplinary approach may better serve reconstructive urology patients in the long term.
