Result of En Bloc Renal Hilar Ligation during Laparoscopic Radical Nephrectomy and Laparoscopic Radical Nephroureterectomy
Keywords:

Background: En bloc renal hilar ligation has historically been associated with very rare complicationof renal arteriovenous fistula (AVF). Most urologists dissect out renal artery and vein separately to avoid this complication but the procedure increases the operative time and risk of vascular injury.
Objective: To study result of En bloc renal hilar ligation during laparoscopic radical nephrectomy (LRN) and laparoscopic radical nephroureterectomy (LRNU).
Material and method: A retrospective review was performed in consecutive 80 patients at 1, 6, 12, 24, 36, 48 and 60 months follow-up. The subjects were patients underwent LRN and LRNU, en bloc renal hilar ligation technique, between June 2007 and June 2012 by one surgeon.
Results: Mean age of the patients was 60.19 years. Indications for surgery were renal cell carcinoma (65%), transitional cell carcinoma (20%) and others (15%). There was no complication related to this technique, particularly AVF, at the mean follow-up of 39.51 months.
Conclusions: This study showed no evidence of AVF. En bloc renal hilar ligation is safe and effective. This technique can be utilized in noninflammatory renal diseases without potential vascular injury.
