Simplified treatment of ectopic ureterocele in 35 children.

From 1970 to 1977, 35 patients with ectopic ureterocele underwent a simplified treatment which consisted of the removal of the upper part of the kidney and its dilated ureter, but with no attention to the intravesical swelling. The procedure is straightforward and can be performed on very young children in poor physical condition. It can be used in all cases of ectopic ureterocele whether the contralateral upper urinary tract is normally refluxing or dilated. Of 33 cases with a reasonably long follow-up the results were good in 26 cases. In 19 cases the infection disappeared immediately and the ureterocele collapsed. If the lower ureter was dilated there was an improvement of its diameter in 13 of 14 cases. If the ureter was refluxing, the reflux disappeared in most patients. In only 7 patients did the reflux persist, necessitating a reoperation to reimplant the ureter and remove the ureterocele. In seven cases the results were not satisfactory: one case of dilatation in the superior contralateral urinary tract, two cases of persistence of reflux in the lower ureter and 4 cases in which the urinary infection persisted.
