UTIs occur in all individuals, but age, sex, pregnancy, diabetes, urinary catheter, and vaginal intercourse increase the risk of development. UTIs are divided into cystitis (lower tract and bladder) and pyelonephritis (upper tract and kidneys). Cystitis symptoms include dysuria, increased frequency, urgency, and occasionally suprapubic tenderness. Pyelonephritis is characterized as cystitis symptoms plus fever, flank pain, nausea, and/or vomiting. Elderly patients frequently do not experience specific urinary symptoms, but may present with altered mental status, change in eating habits, or gastrointestinal symptoms. In addition, patients with indwelling catheters or neurologic disorders commonly will not have lower tract symptoms. Instead, they may present with flank pain and fever.
