One of #radonc oldest dogmas: No full bladder, no treatment. Countless patients have spent years anxiously drinking water, waiting, and hoping they got it "just right." We asked a simple question: Do we really need a full bladder for prostate SBRT?

So we tested it. In the Phase II EMPTY-RT trial, 118 patients underwent prostate SBRT using an empty bladder protocol. doi.org/10.1016/j.ijrobp.202… 28.1% acute grade ≥2 GU AEs <1% grade 3 GU AEs Very similar to the full bladder PRIME trial SBRT presented @ESTRO_RT

Why this matter? Full bladder protocols add anxiety, delays, repeat imaging, and workflow inefficiencies. If an empty bladder is just as safe, simpler may actually be better. @TylerSbrt @piet_ost @alison_tree @HimanshuNagarMD @aleberlin2 @PaulSargos @ASTRO_org

What is next? No more laxatives? Leave the rectum as is?

C’mon, this is the birth of POOP-RT; can’t run away from it that easily. 🤪
