Is it okay to treat simple UTI's with a shorter course of antibiotics?

In some cases, yes.
The standard regimen has traditionally been a 3-day course of trimethoprim-sulfamethoxazole, commonly called TMP-SMX (Bactrim, Cotrim, Septra).
Fluoroquinolone antibiotics, also called quinolones, have usually been a second choice. However, in geographic areas that have a high resistance to TMP-SMX, quinolones are now the first-line treatment for UTIs. Ciprofloxacin (Cipro) is the quinolone antibiotic most commonly prescribed. Quinolones are usually given over a 3-day period.
Nitrofurantoin (Furadantin, Macrodantin) is a third option. This drug must be given for longer than 3 days.
Other antibiotics may also be used, including amoxicillin (with or without clavulanate) doxycycline and cephalosporins. Doses are usually given for 3 to 7 days.

Every antibiotic has a recommended length of time it should be given. This is the length of time it takes for the antibiotic to work. If you take a shorter course of the antibiotic, you can possibly have a regrowth of the bacteria because they weren't all gone.
