OBJECTIVES: As experience with laparoscopic partial nephrectomy (LPN) expands, inevitably @entity703 with @entity8 will be subjected to LPN. We evaluated LPN in kidneys with multiple arteries and compared those outcomes with the LPN outcomes in @entity1 with conventional renal arterial anatomy. METHODS: Since September 1999, we have performed LPN for @entity5 in 333 @entity1 . From this prospectively maintained database, we identified 60 @entity1 with @entity8 and 273 @entity1 with a single renal artery to the operated kidney. All @entity1 underwent three-dimensional computed tomography preoperatively for accurate delineation of the @entity5 and renal vascular anatomy. The clinical and operative data were reviewed to assess critical outcomes. RESULTS: The baseline parameters, including @entity5 size (P = 0.87), were similar in the two groups. Intraoperatively, the method of vascular control, @entity5 parenchymal extension depth (P = 0.40), number requiring pelvicaliceal repair (P = 0.62), and specimen weight (P = 0.49) were similar between the two groups. Similarly, the warm @entity63 time (P = 0.60), operative time (P = 0.15), @entity190 (P = 0.37), and intraoperative (P = 0.52), postoperative (P = 0.48), and late complication (P = 0.64) rates were similar between the two groups. CONCLUSIONS: LPN can be efficaciously performed in the presence of multiple renal vessels. Preoperative evaluation with three-dimensional computed tomography is recommended to have preoperative knowledge of the renal vasculature and thereby minimize @entity130 .
