How long do false passage take to heal?

From trauma during a cystoscopy I now have a false passage. 

Had a catheter for one week and currently have good flow. Prescribed Cipro for 2 weeks. 

Anyone have experience with a false passage and how long does it take to heal? Is it probable that a stricture would occur?

Wow, sorry for you.  My uro said that false passages come from cathing misses.
