Abstract
Children (51) had unilateral ureteric reimplants for primary vesicoureteric reflux over an 11 yr period. Reflux was abolished in 50 patients but in 8 (15.7%) it developed or became worse on the contralateral side. An isotope renal scan (99mTc-DMSA) was carried out in 15 of the 18 patients who had grossly scarred or dysplastic kidneys. Thirteen of these had < 22% of total function coming from the affected kidney and 7 had < 10% of their total GFR [glomerular filtration rate] coming from the kidney whose ureter had previously been reimplanted. Five of these children underwent nephrectomy; this would have been a better initial procedure. No patient was hypertensive at the conclusion of the study.
