Objectives: To analyze our series of primary congenital diverticula (PCD) and their association with vesicoureteral reflux. Methods: We have taken care of 23 children with PCD. Eleven of them had big diverticula ( 2 cm) and twelve small. In the first group, 4 children had vesicoureteral reflux and 5 in the second group. In group A, ureteral reimplantation was performed at the time of diverticulum excision. Nor diverticula neither refluxes were operated in group B. Results: We analyze separately results in both groups. Group A: Patients were operated including diverticulum excision. There were not recurrences except in one case with Ehler-Danlos Syndrome. No reimplanted ureter showed postoperative reflux. Nevertheless, one case with multiple bladder diverticula without reflux presented reflux after the excision of several diverticula without reimplantation. Group B: Small diverticula did not undergo surgery. Spontaneous outcome of reflux was similar to that of the general population without diverticula. Conclusions: Bladder diverticula are frequently associated with vesicoureteral reflux. The presence of reflux is not an absolute condition for surgical or endoscopic treatment. When diverticula are big in size (Group A) the indication for surgery comes from recurrent infection or voiding disorders, not from reflux. If they undergo surgery, ureteral reimplantation is performed in the case they had reflux or for technical reasons like bladder wall weakness. When diverticula are small (Group B) the presence of reflux does not condition treatment, being the rate of spontaneous resolution similar to the general population.
