E. coli urinary infections
6. Urgency to urinate and frequent urination

It is the most frequent symptom in patients with urinary infections. In E. coli, this is caused by an irritation of the urinary tract and inflammation of the urinary bladder. In this case, the patient becomes unable to hold his or her urine for very long, and they need to go to the bathroom several times, sometimes waking up in the middle of the night to do so. In males with these symptoms, it is important to differentiate urinary infections with prostatitis, which may also be caused by an E. coli infection. In prostatitis caused by E. coli, patients have a swollen and hot prostate to the touch and may develop a prostatic abscess with fever and chills.
