[Puerperal infection of the urinary tract]

An urine routine and bacteriological analysis was performed in 100 female patients in third "trimester" of pregnancy and in the second day after delivery. When bacteriuria was detected a next urine bacteriological examination was done in 8-10 and 30-50 days after the delivery. A rate of bacteriuria in female patients before the delivery was 33% and after 56%. The results of routine urine analysis were in normal limits in 31.1% of females with significant bacteriuria. A spontaneous disappearance of bacteriuria between 8 and 50 day after the delivery was observed in 46.6% of patients, but in 53.4% symptoms of urinary tract infection were noticed. Escherichia coli (serotype A and B) was defined in 79.3% of observed urinary tract infections.
