So Felix, would you like to add something to that? Any tips and tricks from your side?

Yeah, we already mentioned that we are in some cases not that lucky to have really good or really well-trained radiologists in order to perform this.

So we better learn how to do the exploration ourselves.

And it's really important to really expose the entire length of the urethra, particularly in the valve segment we are covering today in our talk.

And for this, it's really important just to have the patient, you will have the patient flat in the in the x-ray table we need to rotate the c x-ray arc in order around 30 degrees something with 30 degrees is fine and by that way we're going to expose completely the the valve bar segment when we're filling it with contrast and in some cases we have the pelvic arch over the vulva area, it could be nice also to slightly tilt the C-arc towards the head or towards the legs of the patients in order to move the pelvic arch out of the way and completely see the vulva when we are filling it with contact.

These are our tips to perform.

What's the definition of success you use? Do you use anatomical, functional, and how would you reflect on long-term follow-up?

I think we already briefly mentioned that when we were speaking about the outcomes of the drug-coated balloon, that the outcomes for the endoscopic treatments are mostly related with the absence of retreatment that is considered the classical functional approach, that is a pragmatical approach, the patient.
