In brief: Depends
It will depend upon the organism producing the UTI and its sensitivities to antibiotics, and the nature of the UTI (upper v.
Lower tract infection, simple v. Complicated, etc.) most of the antibiotics in general use today are safe, and even if they enhance renal insufficiency this is often reversible. Would, however, stay away from aminoglycosides (gentamicin, tobramycin, etc.).

In brief: Amoxicillin,
Macrodantin or Cipro (ciprofloxacin) are all safe.

With macrodantin it depends upon the duration of therapy. This agent, structurally related to dilantin, may create side-effect problems if used long-term.
