Has anyone had side effects from sertraline on the bladder?

Hi, Lou!
This is from the literature which says urinary side effects are possible:
"Common (1% to 10% of users): Urinary incontinence, urinary retention
Uncommon (0.1% to 1% of users): Micturition disorder, nocturia, pollakiuria, polyuria"
If you're having problems like these you should let your doctor know.
Best regards and I hope this helps.
