Thanks for the query.
If there was any pressure on the bladder or urethra
during the laparoscopic procedure that can lead to sloughing of the tissue and formation of fistula.
By doing all procedures your doctors might have came to one conclusion regarding the presence and type of the fistula.
Now depending on the site and size of the fistula you can go for corrective surgery.
After surgery possibly you may not further complications.
