Bladder infections overall rarely require an emergency room visit, but some people are more likely to have complications from the infection, including pregnant women, the elderly, men, diabetics, kidney problems, or poor immune systems. Do I have an infection or another problem? Although urination is usually the main manifestation of a UTI, it can also be a manifestation of other conditions, like mycosis fungoides or certain sexually transmitted diseases (STDs). STDs have chlamydia, gonococcus and trichomonas, and a simple laboratory test can separate STDs. interstitial cystitis has many of the same symptoms as bladder infections, and can occur in both men and women, requiring cystoscopy to identify them.
