The First Tissue Engineered Neo-Urinary Conduit (NUC) Clinical Trial for Complete Organ Replacement: Successes, Pitfalls, Challenges – Summary:
Trinity J. Bivalacqua, MD, PhD, Director of Urologic Oncology at Johns Hopkins Medicine, discusses the first tissue-engineered neo-urinary conduit (NUC) clinical trial for complete organ replacement in patients with bladder cancer. He explains that the standard methods of using the genitourinary (GI) tract for cystectomy in patients with bladder cancer often cause sustained and significant complications associated with exposing the GI tissue to urine, and therefore the development of a urinary diversion using autologous cell sources for a tissue-engineered urinary conduit is warranted. Dr. Bivalacqua then details the process by which his team attempted to do this: isolating smooth muscle cells, seeding them on a biodegradable PLGA scaffold, and then implanting the construct after cystectomy, first in porcine subjects and then in human patients during the phase I trial. He notes that while all the NUCs had to be explanted due to stomal stenosis or NUC stricture, his team did successfully regenerate urinary tissue using smooth muscle cells, and he hopes researchers will progress toward the development of a clinically functional urinary conduit in an ongoing multicenter phase I/II trial.
About The 40th Annual Ralph E. Hopkins Urology Seminar:
The Ralph E. Hopkins Urology Seminar is a multi-day meeting focused on training urologists in the latest in assessing, diagnosing, and treating urologic conditions in the clinical setting. Updates are provided on urologic cancers, stone disease, urologic reconstruction, female urology, infertility, emerging surgical techniques, and general urology. Dr. Bivalacqua presented this lecture during the 40th iteration of the meeting on February 5th, 2020 in Jackson Hole, Wyoming.
