Objective To evaluate the value of retroperitoneal laparoscopic adrenalectomy for benign adrenal tumors.Methods From March 2003 to May 2008,78 patients with adrenal tumors received retroperitoneal laparoscopic adrenalectomy in our hospital. During the operation,three trocars were introduced into the lumbar region to establish retroperitoneal space by blunt dissection with the camera. Afterwards,the tumor was removed by using a harmonic scalpel. Results The procedures were successfully completed in all the 78 cases without blood transfusion,the operation time ranged from 45 to 180 min (mean,90 min). Drainage tubes were removed 24 hours after the operation. And the patients were discharged from hospital in 3 to 5 days postoperation. One patient showed regional subcutaneous emphysema after the surgery and was cured spontaneously. The patients were followed up for 3 to 24 months with a mean of 10 months,during which 36 patients achieved normal blood pressure in 3 months,while in the other 7 patients,oral antihypertension drugs were still needed. No patients had recurrent tumor during the follow-up. Conclusions Retroperitoneal laparoscopic can be the first choice for adrenal tumors,as it is safe and effective with minimal invasion,quick recovery,and short postoperative hospital stay.

Objective To compare the estimated CFR (eCFR) values using the new chronic kidney disease epidemiology collaboration (CKD-EPI) equation with those from the abbreviated MDRD equation in a Chinese cohort with chronic kidney disease (CKD) and to analyze the impact of the new CKD-EPI equation on the staging of CKD. Methods A total of 450 Chinese patients (239 female and 211 male) with CKD were enrolled. eCFRs obtained by the CKD-EPI equation and the abbreviated MDRD equation were compared with the Bland and Altaian method. The agreement between two equations in CKD staging was assessed by Kappa test. Results Mean eGFR was 2.4 ml ·(min)-1 ·( 1.73 m2)-1 higher with the CKD-EPI equation as compared to the abbreviated MDRD equation. The percentage of CKD staging concordance between equations for stage 1, 2, 3A, 3B, 4, and 5 was 97.10% (n=67), 80.77% (n=105), 6 0.86% (n= 48), 87.69%(n=57), 90.38% (n=47) and 98.18% (n=54) respectively. Kappa index was 0.913 (95%C/: 0.881-0.945). The CKD-EPI equation reclassified 19.23% (n=25) and 39.24% (n=31) of patients with CKD stage 2 and 3A,upward to a higher eCFR category. Conclusions The new CKD-EPI equation reclassifies a number of patients to higher CKD stages, especially those classified as CKD stage 2 or 3A by the abbreviated MDRD equation.
