摘要： The treatment of small renal masses has shifted from radical nephrectomy to partial nephrectomy, in particular, laparoscopic partial nephrectomy. Renal artery clamping is often necessary to minimize hemorrhage during resection in cases of partial nephrectomy. However, renal artery clamping may lead to greater incidence of renal malfunction after partial nephrectomy. Therefore, novel techniques which could both avoid renal artery occlusion and achieve adequate hemostasis are urgently required. Selective renal segmental artery clamping was one of several common methods that could achieve “zero ischemia.” At the same time, a number of reports about laser?assisted partial nephrectomy on humans using multiple kinds of outstanding coagulative specialties of lasers were published. Among facilities with clinical use of lasers, diode laser emitting a wavelength of 980 nm has been recently utilized in the human body operations. The purpose of our clinical research was to evaluate the effectiveness and safety of application of diode laser (980 nm wavelength) in laparoscopic partial nephrectomy with highly selective clamping of the segmental renal arterial.
