Laser-assisted partial nephrectomy in children.

The authors present three case reports showing the efficacy of laser surgery in performing partial nephrectomies in children who had bilateral Wilms' tumors and duplicated systems with obstructed nonfunctioning upper pole moieties. Using both the KTP laser (for cutting) and the YAG laser (for coagulation of large vessels) allows for fast removal of kidney tissue, with minimal blood loss and minimal loss of renal parenchyma.
