ABSTRACT
Objective To evaluate the safety and efifcacy of Laparoscopic partial nephrectomy (LPN) versus 1aparoscopic cryoablation (LCA) for the small renal tumors (SRMs).Methods The databases of PubMed, SCI, Ovid, the Cochrane Library, CNKI, CBM, VIP and Wangfang Data were searched to controlled clinical trial about LPN versus LCA for the treatment of small renal tumor. The retrieval time span was from inception to Apr 2016. The studies were screened according to the inclusion and exclusion criteria, the date were extracted and the quality was evaluated by 2 reviewers independently. And then the Meta-analysis was conducted using RevMan 5.3 software.Results 9 studies were included, and 748 cases were involved. The meta-analysis showed that comparing with LPN, the operation time of LCA was shorter [MD = 42.75, 95 % CI (12.19~73.31),P = 0.006], less intraoperative blood loss [MD = 190.73, 95 % CI (126.67~254.78),P = 0.000], shortening hospital stay [MD = 2.23, 95 % CI (0.17~4.28),P = 0.030], lower transfusion rate [OR
