OBJECTIVE: To compare the safety, feasibility and efficacy of transperitoneal and retroperitoneal laparoscopic partial nephrectomy (LPN) in the treatment of @entity703 with R. E. N. A. L score more than 7. METHODS: The clinical data were collected from 62 @entity1 undergoing transperitoneal LPN (32 cases) and retroperitoneal LPN (30 cases) for a complex renal mass (R.E.N.A.L. score>= 7) between January 2012 and March 2014. The surgical and early postoperative outcomes and complications were analyzed to evaluate the efficacy of the treatments. The mean operative time, estimated @entity190 , warm @entity63 time, surgical complications, blood transfusion rate, tolerating regular diet time, postoperative hospital stay and surgical margin were compared between the two groups. RESULTS: The operations were completed successfully in all cases except for 1 case in transperitoneal group and 3 in retroperitoneal group that required conversion to open surgery. No significant differences were found in age, body mass index, ASA score, Charlson comorbidity index, @entity5 size or R.E.N.A.L. nephrometry score (P>0.05), nor in estimated @entity190 , warm @entity63 time, @entity3816 , blood transfusion rate or surgical margin between the two groups (P>0.05, respectively). The transperitoneal LPN group had a shorter mean operative time than retroperitoneal LPN group (210.4   59.2 vs 252   58.3 min, P<0.05) but showed longer tolerating regular diet time (47   10 h vs 23   6 h, P<0.05) and postoperative hospital stay time (8.4   1.9 days vs 6.5   1.6 days, P<0.05). CONCLUSION: Both transperitoneal LPN and retroperitoneal LPN are safe, feasible and effective for surgical management of complex localized @entity5 , but the transperitoneal procedure offers larger operative space with better exposure; the retroperitoneal procedure better promotes postoperative recovery of the @entity1 .
