    AbstractLong-term follow-up studies have demonstrated that effective local tumor control and long-term tumor-free progression rates can be achieved by nephron-sparing surgery. However, hemostasis is a major issue and the lack of effective means of hemostasis has limited a wider use of the laparoscopic approach to nephron-sparing surgery. Between January 2001 and August 2002, a total of 36 patients with renal cell carcinomas were treated by partial nephrectomies using a two-component tissue sealant (FloSeal). The median age was 55.2 years (range: 34-71 years). Follow-up time was 1-18 months (median: 5.5 months). The tumor diameter ranged from 2 to 5 cm (median: 2.9 cm). Open retroperitoneal surgery was performed in 17 cases and laparoscopic partial nephrectomy in 19 cases. The two-component tissue sealant (consisting of a gelatin matrix with granular and thrombin components) was applied after resection of the tumor and before perfusion of the kidney. The following parameters were recorded: (1) time until complete hemostasis was achieved, (2) decrease in postoperative hemoglobin level, (3) postoperative bleeding, and (4) presence or absence of a perirenal hematoma 24 h and 10 days postoperatively by ultrasound. After application of the tissue sealant for 1-2 min to the moist resection site, hemostasis was immediate in all cases. During the laparoscopic partial nephrectomies, a laparoscopic applicator was used that avoided wasting the tissue sealant within the dead space of the instrument. When reperfusion of the kidney was established, hemostasis was maintained. The decrease in postoperative hemoglobin level ranged from 0.3 to 1.2 points (median: 0.8 points). None of the patients required blood transfusions. There were no cases of postoperative bleeding. An ultrasound examination 24 h and 10 days postoperatively demonstrated the absence of a significant perirenal hematoma. The two-component tissue sealant FloSeal provided immediate and durable hemostasis in open and laparoscopic partial nephrectomies. The tissue sealant may provide a tool to expand the possibilities of laparoscopic nephron-sparing surgery.
