Laparoscopic partial nephrectomy with "on-demand" clamping reduces warm ischemia time.

Objectives: To investigate the impact of "on-demand" clamping during laparoscopic partial nephrectomy on warm ischemia time.

Methods: We retrospectively reviewed 39 consecutive patients with renal tumors who had undergone transperitoneal laparoscopic partial nephrectomy from April 2002 to May 2006. Median tumor size was 2.

Laparoscopic live donor right nephrectomy: a new technique to maximize the length of the renal vein using a modified Endo GIA stapler.

Objectives: To report the utilization of a modified Endo GIA vascular stapler to obtain the full length of the renal vein during transperitoneal laparoscopic live donor right nephrectomy.

Methods: We used a modified Endo GIA stapler, in which the triple staggered rows of staples were removed from the kidney donor side to obtain the full length of the right renal vein. This technique has currently been used in nine consecutive transperitoneal laparoscopic right donor nephrectomies.
