title: [Chylous leakage after retroperitoneoscopic upper-pole heminephrectomy for duplex kidney].
abstract: OBJECTIVE
  To discuss management of chylous leakage after retroperitoneoscopic upper-pole heminephrectomy for duplex kidney.
  
  
  METHODS
  Between November 2004 and Februar y 2011, 39 patients underwent retroperitoneoscopic upper-pole heminephrectomy for duplex kidney, of these 5 patients had chylous leakage. The ages of the patients ranged from 32 to 60 years (mean 42). All the patients were treated conservatively, and the therapeutic effects were observed.
  
  
  RESULTS
  Delayed chylous leakage in 5 patients occurred 5-31 days after surgery, and leakage occurred in 4 of the same 5 patients during the first 2 post-operative years. Chylous leakage after retroperitoneoscopic upper-pole heminephrectomy for duplex kidney preferentially occurred at the left side of duplex kidney. All the patients healed under conservative treatment.
  
  
  CONCLUSIONS
  Chylous leakage typically occurs after left retroperitoneoscopic upper-pole heminephrectomy for duplex kidney, and can be prevented by improving surgical technique; it can be completely relieved by conservative management with satisfactory results.
