I don’t how your search has gone, but FWIW I met with Dr. Lee C Zhao (part of TURNS organization) in NYC yesterday, and had a great initial experience. He works at NYCU Langone. I flew in from Western NY, and had a consultation with him & his staff.
He advised he does apprx 120 surgeries regarding urethral strictures per year, and made me feel at ease as I could tell this was a regular day in the office for him. He also noted that he has many clients from overseas & people who travel to see him (including myself).
I did a cystoscopy on site as well as a flow test, which were a breeze compared to my first set of tests at a local hospital. The plan is to eventually conduct surgery, and they will have to use some skin from the inside cheek as well. Him and his staff were very friendly and informative, I actually showed up to my apt 2 hrs early and they took me right away. The total visit was about 2 hours or so. I highly recommend looking into if your insurance would accept him and if it would be feasible. For me, paying $200 USD for a round-trip plane ticket a few times is worth it, if I can fix this mess….
