title: [Retroperitoneoscopic dismembered pyeloplasty in children].
abstract: OBJECTIVE
  To evaluate the technique and the clinical efficacy of Retroperitoneoscopic dismembered pyeloplasty in children.
  
  
  METHODS
  Retroperitoneoscopic dismembered pyeloplasty was performed on 17 patients of pediatric ureteropelvic junction (UPJ) obstruction, age ranging from 3 - 10 years. All patients had radiographic evidence of obstruction with signs, symptoms or deterioration of renal function.
  
  
  RESULTS
  All of the 17 operations were performed successfully, and no serious complications occurred during and after the operations. Average operating time was 4.3 hours, which decreased with surgeon experience. Average blood loss was 38 ml, mean postoperative stay was 4.6 d. Only one case had postoperative urine leakage. With a mean follow-up of 14 months, all patients were free of obstruction on follow-up radiographic imaging.
  
  
  CONCLUSIONS
  Retroperitoneoscopic dismembered pyeloplasty is a safe, effective and minimally invasive procedure for treatment of UPJ obstruction in children, and it can be used as an alternative to open surgery.
