Methods: From August 1 997 to October 2008, 48 cases of small renal cell carcinomas were confirmed by surgery and pathology, and reviewed retrospectively. Of the 48 cases, there was 1 patient with bilateral tumors, 8 with solitary kidney tumors, 1 with unilateral tumor and a damaged contralateral kidney, and 38 with unilateral tumors and a normal contralateral kidney; 9 underwent tumor enucleation and the remaining patients received partial nephrectomy. Results:There were no local tumor recurrences and/or tumor metastasis at a mean followup of 60 months. Conclusion: Confirming conclusions from other centers, we have found that nephron-sparing surgery is an effective treatment for small renal cell carcinomas.展开更多

Methods: This study enrolled 40 patients with a normal contralateral kidney and without a renal function threatening risk factor, who were operated with NSS. The patients were randomized at admission. They were divided into 2 equal groups as warm and cold ischemia. An ice application for 10 minutes was done to cold ischemia group after clamping renal artery. Renal functions were evaluated with Technesium-99m-Dimercaptosuccinic Acid (DMSA) and serum creatinine at the preoperative and postoperative (day 1, day 15, month 6, and month 12) period. Statistical analysis was done with Mann Whitney U test, Wilcoxon Signed Rank test, and Fredman test. A p value below 0.05 was considered statistically significant. Results: There were no significant differences between the groups in terms of age, body mass index, ischemia time, tumor size, amount of hemorrhage, and procedure time. Both groups had a significantly higher DMSA uptake at the preoperative period compared with the postoperative period (postoperative day 1, day 15, month 6, and month 12) (p 0.001). However, both groups had similar DMSA uptake results at the postoperative period. Preoperative and postoperative creatinine levels were not significantly different from each other in both groups. Conclusion: Based on tumor localization, nephron sparing surgery without use of superficial cooling appears as a viable option for small renal masses.展开更多

The two patients underwent different laparoscopic interventions at Ukrb University (Neuruppin, Germany): nephrectomy and Anderson-Hynes-pyeloplasty. All procedures were completed, with no need for conversion or placement of additional ports. No intraoperative complications or technical failure of the instrument was recorded. The mean operative time was 180 min median length of stay was 11.5 d. The instrument could be opened out of the sterile packaging and used at once when it was needed, because it is a single-use instrument. There was real haptical feedback and the costs are minimal compared to robot surgery. The use was straightforward and rapid processes after an intensive training of 4 h in a dry lap. Awaiting future investigations in larger series, this study proves the safety and feasibility of renal surgery with ArtiSential<sup>TM</sup> and provides relevant data that may help early adopters of this surgical instrument.展开更多
