Recurrent urinary infections in girls: relation to enuresis.

Maximum bladder capacities (MBC) have been studied in 89 girls receiving treatment for urinary infections at a time when the infection had been controlled. Fifty-six of the girls had been enuretic when first seen, 40 remained enuretic even when the infection had been cured. The MBC's of the enuretic children were significantly smaller than those who were not or had not been enuretic. The enuresis and small bladder capacities were therefore not usually due to the urinary infection. It is concluded that in girls either enuresis predisposes towards the development of urinary infections, or that a common underlying pathology predisposes to both entities.
