The purpose of this study is to compare the efficacy and safety of the segmental artery clamping and main renal artery clamping during laparoscopic partial nephrectomy
Renal tumor patients,for whom laparoscopic partial nephrectomy is suitable, will be randomly divided into two groups,segmental artery clamping group and main artery clamping group. All procedures were performed by the same laparoscopic surgeon. Blood loss, operation time, warm ischemia time, complications and affected renal function before and after operation will be recorded and compared. The safety and efficiency of laparoscopic partial nephrectomy with segmental renal artery clamping will be evaluated in comparison with the conventional main renal artery clamping technique.

| Segmental artery clamping | Experimental | Patients with Renal tumor are randomized into this group,they will received laparoscopic partial nephrectomy. During operation, the technique of segmental renal artery clamping will performed. |
|
| Main renal artery clamping | Active Comparator | Patients with renal tumor are randomized into this group,they will received laparoscopic partial nephrectomy. During operation, the technique of traditional main renal artery clamping will be performed. |
