Urethral syndrome?: Some UTIs are limited to the urethra, i.e. not involving the bladder, called urethral syndrome. Urinalysis often is normal, with few or no white blood cells; and urine culture also negative, with fewer bacteria than most UTIs. Other things also could do this, e.g. irritation from vaginal perfumes, spermicide, yeast infection, condom (latex) allergy, and more. Discuss with your doctor. Good luck!
