Histological and Urodynamic Study of the Bladder in Enuretic Children

In a study of the bladders of 12 enuretic children by cystoscopy, light microscopy and urodynamics, cystoscopic trabeculation was found in 10 cases. Histologically, the trabeculation resembled adult trabeculation of obstructive aetiology, collagen infiltration being the characteristic hallmark. Using urodynamic measurements, the bladders behaved like those of adult enuretics; 10 out of 12 were unstable and voiding occurred at relatively high pressures. There was no correlation between symptoms and either cystoscopic or histological trabeculation.
