RT Journal Article SR Electronic T1 Preventing recurrent cystitis JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 93 OP 94 DO 10.1136/dtb.11.24.93 VO 11 IS 24 YR 1973 UL http://dtb.bmj.com/content/11/24/93.abstract AB We recently reviewed the use of long-term low-dose chemotherapy to prevent recurrent urinary infections1 and briefly mentioned instructions which could be given to patients to supplement the drug treatment. The effectiveness of such measures is not readily tested by conventional trials, but many clinicians consider that they can help patients with bacterial cystitis and are also worth trying in those women with frequent symptoms of cystitis but without bacteriuria. Only about half the women presenting with urinary symptoms in general practice have infected urine. Recurrent urinary symptoms may be due to the urethral syndrome, gynaecological disorders or even psychiatric disturbances.
