Recurrent urinary infections in general practice.

Repeated episodes of acute, symptomatic urinary tract infections in domiciliary patients have been shown to be due to reinfection in 71% of instances and to recrudescence of the original infection in 29%. Fresh episodes occurring at intervals of less than eight weeks from the original infection were due to reinfection or to recrudescence of infection in roughly equal numbers but those at intervals of eight weeks or more were due to reinfection.
