abstract: OBJECTIVE
  To study the safety and effectiveness of heminephroureterectomy by horizontal lumbar posterior approach for duplicated systems in infants.
  
  
  METHODS
  Thirty-three heminephroureterectomies by lumbar posterior approach were performed in 31 infants at a mean age of 6.7 +/- 5.5 months (range: 1 to 26 months) from January 1994 to December 2005.
  
  
  RESULTS
  The mean operative time was 121 +/- 35 minutes (range: 60 to 190 minutes). No intra-operative complication was observed. Blood loss was minimal (< 20 ml) in all cases. The mean hospital stay was 4.6 days (range: 2 to 7 days). No postoperative complication (urinoma, infection or haemotoma) occurred. No atrophy or major functional loss of the remaining moiety was observed. The mean follow-up was 52.6 +/- 40 months (range: 1 to 151 months).
  
  
  CONCLUSIONS
  The lumbar posterior approach is safe and reproducible and provides an obvious cosmetic benefit in comparison to the standard anterolateral lumbotomy. It represents a procedure of choice for open heminephroureterectomy in infants.
