title: The pseudo-obstructed bladder in enuretic children.
abstract: In a minority of enuretic children with severe day symptoms, and especially when there is urinary infection, there a bladder diverticula and trabeculation and possbily also harmful vesicoureteric reflux which suggest the presence of an infravesical obstruction. However, in 11 children with this syndrome who underwent urodynamic studies, no anatomical or functional obstruction was demonstrable. It is contended that the obstructive signs are the result of uninhibited detrusor contractions being voluntarily resisted by contraction of the external urethral sphincter so that abnormallay high intravesical pressures result. Management involves the use of detrusor-inhibitory drugs. Ureteric reimplantation may be needed for reflux. In the majority of cases symptoms improve with time but the bladder diverticula persist.
