ABSTRACT

OBJECTIVES: We designed the study to compare the oncologic and renal function outcomes of off-clamp, laparoscopic partial nephrectomy (OCLPN) and conventional laparoscopic partial nephrectomy (HCLPN) for renal tumors. METHODS: Between March 2008 and July 2015, 114 patients who underwent laparoscopic partial nephrectomy (LPN) of a renal neoplasm were studied. We performed LPN without hilar clamp on 40 patients (OCLPN, Group 1), and conventional LPN with hilar control and renorrhaphy on another 40 patients (HCLPN, Group 2). We retrospectively reviewed the medical records of each patient's age, sex, R.E.N.A.L. nephrometry score (RNS), operation time, complications, hospitalization period, tumor size, positive resection margin, histologic classification of tumor, pathologic stage, Fuhrman grade, estimated blood loss (EBL), warm ischemic time (WIT), and estimated glomerular filtration rate (eGFR) before and one year after surgery. RESULTS: There were no significant differences in age, sex, preoperative eGFR, EBL, surgical (anesthesia) time, and tumor size between the two groups. The mean eGFR was not significantly different between the OCLPN and HCLPN groups 1 month (95 and 86.2 mL/min/1.73 m², respectively; P = 0.106), 6 months (92.9 and 83.6 mL/min/1.73 m², respectively; P = 0.151) and 12 months (93.8 and 84.7 mL/min/1.73 m², respectively; P = 0.077) postoperatively. The change in eGFR after one year was 3.9% in the OCLPN group and −7.9% in the HCLPN group. CONCLUSIONS: OCLPN was superior to HCLPN in preserving renal function one year after surgery, and there was no statistically significant difference in tumor treatment results.

ABSTRACT

Objective To evaluate the efficacy of using dual laser system in off clamp nephronsparing surgery.Methods We used dual laser system in the patients who underwent off-clamp NSS between Jan 2016 and Apr 2016 in our institution.There were 16 males and 8 females with average age of 49 years.Mean tumor size was 1.9 cm (range 0.8-3.2 cm).The mean R.E.N.A.L.score was 3.8 (range 3-6).The mean Zhongshan score was 3.5(range 3-5).The mean ZⅡ(zero ischemia index)was 1.6(range 1-4).The Evolve Dual (980 nm/1 470 nm) laser system set at 60 W in continuous mode was used.Results Offclamp NSS was successfully performed in 22 patients except for renal artery occlusion in 2 case.Mean operative time was 74 min(range 50-100 min);The average estimated blood loss was 52.9 ml(range 10-200 ml);Mean postoperative drainage was 65.4 ml(range 20-150ml);Mean postoperative hospital stay was 5.2 days (range:4-7days).No severe post-operative complication was found.The mean pre-and postoperative serum creatinine levels were 76.2 μmol/L(range:48-112μ mol/L) and 81.5μ mol/L(range:54-122 μ mol/L) with no significant difference(P >0.05).The postoperative pathology indicated that 20 cases of clear cell carcinomas,3 cases of chromophobe renal cell carcinomas,one case of papillary carcinoma.Conclusions Dual laser system can be used in off clamp nephron-sparing surgery safely and effectively.
