It wasn't. The catheter was (which was done in Mexico, long before he even had contact with U.S. authorities).
It's that simple.
Answered below. Summary: surgery IS required to fix the injury. And the injury was life-threatening. I never said surgery was required to save his life, nor is that in any way germaine to my purpose for providing the doctor’s testimony, which was to disabuse others of the notion that his injury was minor.
The catheter does not fix his problem, it treats a symptom. If you had this problem, and received a catheter, you would not consider yourself “fixed”, you would get the surgery to repair the problem.
More detail is above this post in another reply to your post.
