A preliminary assessment of bladder distension in the treatment of enuretic children.

Urodynamic studies were performed in 22 enuretic children. Each child had previously been investigated to exclude gross psychological disturbance and organic disease and had been treated unsuccessfully in the past by conventional means. 16 of the 22 children showed evidence of bladder instability and were subjected to bladder distension. At follow-up, 4 children were in complete remission of symptoms, 6 had improved and 6 showed no change; the girls responded better than the boys. The interpretation of urodynamic studies, the significance of the results of bladder distension and the possible role of detrusor instability in the aetiology of enuresis are discussed.
