Abstract
We present a 4-year-old girl who underwent a single incision laparoscopic surgery (SILS) heminephrouretectomy. The procedure was completed without intra-operative complications or conversion. The operative time was 162 min. At 3 month follow up there is no evident scar and the patient is asymptomatic. SILS upper moiety heminephrouretectomy for duplex kidney is safe and technically feasible in children.
