In medicine, cystitis is a form of urinary tract infection characterized by "inflammation of the urinary bladder, either from bacterial or non-bacterial causes. Cystitis is usually associated with painful urination (dysuria), increased frequency, urgency, and suprapubic pain."[1]

Staphylococcus aureus is an usual cause that is increasingly occurring.[2] Staphylococcus aureus may be associated with the use of urinary catheterization.[3]

Diagnosis

A clinical prediction rule suggests that if a patient has at least two of 1) dysuria, 2) the presence of more than trace leukocytes, 3) or the presence of nitrites, the diagnosis is sufficiently likely to consider empirical treatment.[4]

Treatment

Consider treatment if:[5]

  • "48-hour delayed antibiotic prescription to be used at the patient`s discretion"
  • or
  • "target antibiotic treatment by dipsticks (positive nitrite or positive leucocytes and blood) with the offer of a delayed prescription if dipstick results are negative"

For uncomplicated cystitis, nitrofurantoin 100 mg by mouth twice a day for 5 days may be used.[6]

Prevention

Systematic reviews by the Cochrane Collaboration regarding the prevention of urinary tract infection
Intervention Number of trials Relative risk ratio
Antibiotics[7]
(Continuous or postcoital)		 10 0.21
Intravaginal estrogen[8] 2 0.25 to 0.64
Cranberry[9] 10 0.65

The following are measures that studies suggest may reduce the incidence of urinary tract infections. These may be appropriate for people, especially women, with recurrent infections:

Selected randomized controlled trials of intravaginal estrogen for the prevention of urinary tract infection
Author, year Duration of study change in pH in treatment group Rates of recurrence Relative risk ratio
Raz, 1993[14] 8 months 5.5 to 3.6 Intravaginal estrogen cream:
16%
 Placebo:
63%
 0.25
Eriksen, 1999[15] 9 months 6.7 to 5.3 Intravaginal estrogen via vaginal ring:
55%
 No treatment:
80%
 0.64
Raz, 2003[16] 9 months 5.6 to 5.3 Intravaginal estrogen via pessary:
67%
 Nitrofurantoin:
52%
  
  • For post-menopausal women, a randomized controlled trial[14] and a meta-analysis[8] by the Cochrane Collaboration has shown that intravaginal estrogen cream can prevent recurrent cystitis. The relative risk of recurrence was 0.25[14] to 0.64[15] in the two trials included in the review. In the original trial in 1993, patients in the experimental group applied 0.5 mg of estriol vaginal cream nightly for two weeks followed by twice-weekly applications for eight months[14].
    • Higher dose of intravaginal estrogen cream (1 mg estriol daily for two weeks then twice a week for two additional weeks) may help premenopausal women for 11 months.[17] However, this study was uncontrolled.
    • Intravaginal estrogen via estriol pessary may not be effective.[16]
    • Intravaginal estrogen may be more effective than continuous oral antibiotics[18]. However, this is not true of the estrogen pessary due to inability to restore normal lactobacilli and lower vaginal pH.[16]
