The role of bladder biofeedback in the treatment of children with refractory nocturnal enuresis associated with idiopathic detrusor instability and small bladder capacity.

Abstract

PURPOSE:

Not all children with primary nocturnal enuresis, an unstable detrusor and small bladder capacity can be treated successfully with anticholinergics and bladder drill. We report our use of bladder biofeedback in patients who did not respond to 3 months of such treatment.

MATERIALS AND METHODS:

A total of 24 patients (median age 10.4 years) were studied. For bladder biofeedback a transurethral catheter was placed and connected with a 3-way connector. The bladder was slowly filled through this catheter and the intravesical pressure could be seen on a vertical tube, which was also connected to the transurethral catheter. The perineal bulbar detrusor inhibiting reflex was used in cases of involuntary bladder contraction. During the day patients retained urine as long as possible and completed a micturition chart.

RESULTS:

Of the 24 patients bed-wetting stopped completely in 17 and decreased in 6, and treatment failed in 1. All patients were followed for at least 6 months after treatment. There were 2 cases of recurrence in the group that was cured.

CONCLUSIONS:

Intravesical biofeedback can successfully treat patients with refractory primary enuresis associated with unstable detrusor and small bladder capacity.
