Abstract

The water-jet system (WJS) can be used for selective dissection of kidney parenchyma without renal artery clamping in laparoscopic partial nephrectomy (LPN). We report our experiences regarding LPN with a WJS. The first case was a 59 year old male with a 1.8 cm solid mass in the Rt. mid-lateral area (R.E.N.A.L score: 5a). The second case was a 24 year old female with a 2.3cm solid mass in the Lt. mid-lateral area (R.E.N.A.L score: 7x). We successfully finished non-clamping LPN using a WJS without perioperative complications. Surgical margins were negative (7mm and 1mm for cases 1 and 2, respectively). Post-operative renal function was not decreased significantly. LPN using a WJS is a feasible and safe technique which can be performed for small renal masses without ischemic damage.
