    Abstract:
    A retrospective study on antireflux surgery for primary vesicoureteral reflux at Hokkaido University Hospital was performed. One hundred and seventy-nine patients (299 ureters) underwent antireflux surgery in these 17 years and 7 months. When the period was divided into 3, success rate was 96.5, 93.8 and 100 per cent, respectively. Overall success rate was 96.6 per cent. There was a combined failure or complication in 9 patients. The records of these 9 were reviewed in detail. Three were believed to be a technical error: 2 stricture and one persistent reflux. The remaining 6 were all children except one and had no clear reason for failure: 2 persistent reflux and 4 contralateral appearance of reflux ("missing VUR"). Four of these 6 patients were characterized by voiding dysfunction, namely uninhibited bladder. In 3 patients reflux disappeared spontaneously by administration of anticholinergic agent. In many of these, vesical diverticulum formation was also noted to precede or to coincide with recurrence or appearance of reflux. Thus other 3 patients with diverticulum formation after antireflux surgery were added and re-evaluated. All 3 children had voiding dysfunction with uninhibited bladder. Diverticulum formation was believed to be related to uninhibited bladder in at least one child. It seems that the child with uninhibited bladder and reflux is particularly at risk for failure or complication of antireflux surgery. Patients with symptoms of voiding dysfunction deserve a complete evaluation, including cystoscopy and urodynamics.
