Abstract
INTRODUCTION: Nephron-sparing surgery is currently the treatment of choice for renal cell carcinoma stage T1a. During the past years, several hemostatic agents (HA) have been developed in order to reduce surgical complications. We present the results of our series and the impact of the use of HA in the prevention of surgical complications in laparoscopic partial nephrectomies (LPNs). MATERIAL AND METHODS: We retrospectively analyzed all LPN performed in our center from 2005 to 2012. A total of 77 patients were included for analysis. Patients were divided into two groups: Group A (no use of HA) and Group B (use of HA). HA used included gelatin matrix thrombin (FloSeal) and oxidized regenerated cellulose (Surgicel). Demographics, perioperative variables, and complications were analyzed with a special interest in postoperative bleeding and urinary leakage. RESULTS: Median age was 57.17 years old (±12.1), 72.7% were male, most common comorbidities were hypertension (33.8%) and diabetes mellitus (18.2%). All patients had one solitary tumor, and 87% had a tumor ≤4 cm. Renal cell carcinoma was found in 79.2% of cases, and 78.7% were stage pT1a. and were used in 36 cases (46.8%). No differences were found in demographics, perioperative variables, and complications between groups. No conversions to open surgery or perioperative mortality were reported. CONCLUSIONS: We conclude that in our series the use of a hemostatic agent did not offer benefit in reducing the complication rate over sutures over a bolster.
