It was great connecting with colleagues, attending meaningful educational sessions and celebrating the work of urologic oncology at the SUO 2025 Annual Meeting in Phoenix. Thank you to everyone who joined us and helped make it such an excellent event.

This is really impressive @jteoh_hk especially also the presence of detrusor muscle in all specimens could indicate that we may be able to get consistent and reliable resection quality with VES #BladderCancer @EurUrolOncol @Oncodaily #ERBT

As a patient— why wouldn’t I want my surgeon to have best possible access, manipulation, and ability to remove all my tumor

VES is a novel robotic surgical system that allows transurethral ERBT. The concentric tube design of the instrument arms allows controllable manipulation at a small diameter of ~1mm. This is extremely crucial to allow a two-handed surgery w/o obscuring the endoscopic view. (2/n)

ERBT is only the beginning! Having a transurethral robotic system with different instruments (e.g.needle holder) allows us to explore new surgical approaches that can never be achieved b4. As a urologist, we should gear up for another exciting robotic journey in the future! (4/n)

We did 6 cases of robotic ERBT in 2 days. 100% detrusor muscle presence, 100% successful ERBT/ modified ERBT, 91% evaluable margins and clear resection margins, no grade 2 or above complications. Small number for sure but the results are indeed very promising. (3/n)

https://t.co/F33X7MplDG TMT for MIBC is a crucial treatment option for our patients. 💵However, its current costs are unsustainable, especially with the growing interest in expanding its use.

BCG > gem for LG IR-NMIBC (better RFS); RARC = ORC (RAZOR: no diff in major comps/readmits —>frailty is the key); bilateral > unilateral primary RPLND for stage II seminoma (cuts RP relapse, ~15% crossover). Good stuff in @JUrology this month:
