My son had to have surgery at age 1 by a urologist from Children's named Max Maizels. The surgery was successful and uneventful. I can't say much about Dr. Max except that he did the job well, and then didn't charge me for a follow-up visit. I was a little irked by his condescending attitude toward one of my questions, but then again, I see that with a lot of doctors when talking to "moms." I haven't had any experience with Dr. Cheng, but I'm sure he's on the same floor/department with Dr. Max. I would tend to believe that all the doctors at Children's are highly qualified. But, you could always do research on him and switch to another urologist if you don't like his style.
