Bladder capacity, urethral sensation and lumbosacral anomalies in children with enuresis.

Thirty-two children with day and/or night enuresis were examined with urography and micturition urethrocystography. They were compared with 139 normal children examined 6 weeks or more after a urinary tract infection. Statistically highly significant differences in urinary bladder capacity, urethral sensation and frequency of lumbosacral anomalies were observed. Only one of 32 patients with enuresis was normal in all 3 aspects while 6 exhibited the complete triad.
