摘要Cystometry is increasingly being used in infants to diagnose bladder dysfunction. However, infantile urodynamic patterns have not been fully established. In this study we investigated the urodynamic patterns in young infants with renal dilation or a history of urinary tract infection, but with no apparent lower urinary tract symptoms. We use video cystometry with simultaneous perineal EMG recording. Thirty-five infants (27 male and 8 female) with congenital renal dilatation or a history of urinary tract infection at age 2 days to 24 months old were involved. We found that detrusor instability occurred in 8.6% of these subjects. Bladder capacity increased with age but less than would nomally be expected. An intermittent voiding pattern was observed in 57% (20/35) of subjects and was characterize by a single or recurring increase in sphincter activity with a simultaneous rise in the voiding detrusor pressure curve. The maximum voiding detrusor pressure wit pelvic floor overactivity was significantly higher than that with no pelvic floor overactivity (105 +/- 44 cmH(2)O vs 69 +/- 22 cmH(2)O, P<0.001). The median post-voiding residual volume was 2 (range 0 to 65) ml. We conclude that in infants with no apparent lower urinary tract symptoms, bladder instability is uncommon, and the capacity is lower than the normally expected range; an intermittent voiding pattern is common and the residual urine volume showed great variation. This probably represents an immature detrusor-sphincter function.
