Ureterosigmoidostomy in bladder exstrophy.

Experience with ureterosigmoidostomy (US) using a reflux prevention technique in 38 of 48 cases of bladder exstrophy is reviewed. During a follow-up period of 14 years, the results were excellent as to morphological changes of the upper urinary tract, incontinence, psychological development and social behavior. Within their families the patients are considered healthy. Even in children with benign disease, US with reflux prevention performed during the second year of life is the operation of choice for urinary diversion. In the postoperative follow-up it is recommended that sigmoidoscopy be performed once a year in addition to routine controls of the upper urinary tract and metabolic balance.
