Cystitis
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]
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.[2]
Treatment
For uncomplicated cystitis, nitrofurantoin 100 mg by mouth twice a day for 5 days may be used.[3]
Prevention
| Intervention | Duration of study | Rates of recurrence | |
|---|---|---|---|
| 8 months | Estrogen: 25% |
Placebo: 65% | |
| Raz, 2003[5] | 9 months | Estrogen: 67% |
Nitrofurantion: 52% |
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:
- Cleaning the urethral meatus (the opening of the urethra) after intercourse has been shown to be of some benefit; however, whether this is done with an antiseptic or a placebo ointment (an ointment containing no active ingredient) does not appear to matter.[6]
- Cranberry juice may decrease the incidence of cystitis according to a systematic review of randomized controlled trials by the Cochrane Collaboration. The Cochrane concluded 'some evidence from trials to show cranberries (juice and capsules) can prevent recurrent infections in women. Many people in the trials stopped drinking the juice, suggesting it may not be a popular intervention'.[7]
- Continuous antibiotic prophylaxis may be beneficial according to randomized controlled trials.[5]
- For post-menopausal women, a randomized controlled trial has shown that intravaginal application of topical estrogen cream can prevent recurrent cystitis.[8] In this study, 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. This may be less effective than 100 mg daily of oral nitrofurantion.[5]
