Laparoscopic partial nephrectomy: hand-assisted technique.

Laparoscopic partial nephrectomy (LPN) is a challenging procedure that has become more popular as techniques have evolved and made the procedure more standardized. We present our hand-assisted technique for LPN. In order to meet the challenges of larger, deeper lesions and to address complications, our technique has evolved from pure hand assistance to hand assistance with hilar clamping and hemostatic adjuncts. We discuss patient selection, preparation and access, renal exposure, preparation of hemostatic agents, resection of the mass, hemostasis, and closure. The results of 76 hand-assisted LPNs (HALPNs) are summarized. While our technique will undoubtedly continue to evolve, HALPN appears to be safe and effective for minimally invasive nephron-sparing surgery.
