Management of unilateral reflux by ipsilateral ureteroneocystostomy--is it sufficient?

The records of 105 patients who had undergone unilateral reimplantation for ipsilateral reflux were reviewed. Patient age, grade of preoperative reflux, completely duplicated collecting systems, preoperative findings of contralateral dilatation of the lower ureter or radiographic evidence of pyelonephritis had no predictive value in regard to the appearance of postoperative contralateral reflux. Of the 105 patients 16 had postoperative contralateral reflux: neurogenic problems were found later in 3, reflux resolved spontaneously within 18 months postoperatively in 9, 1 remains in followup and 3 have undergone repeat operations, for a rectified rate of treatment failure of 3 of 102 (2.9 per cent).
