Amaç: Çalışmamızın amacı parsiyel nefrektomi (PN) operasyonu sırasında hemostatik ajan (HA) kullanımının yaygınlığı ve bu kullanılan HA sayısının hastaların tümör boyutu, RENAL nefrometri skoru (NS), iskemi zamanı ve tümör patoloji sonucu ile ilişkisini araştırmaktır. Gereç ve Yöntem: Kliniğimizde renal kitle nedeniyle Ocak 2013-Şubat 2019 tarihleri arasında PN operasyonu geçiren hastaların kayıtları tarandı. PN sırasında HA kullanılan 71 hasta çalışmaya dahil edildi. PN sırasında HA kullanılan hastaların demografik özellikleri, operasyon bilgileri, patolojik sonuçları ve komplikasyonları kaydedildi. Öz Objective: The aim of this study was to investigate the use and types of hemostatic agents (HAs) used during partial nephrectomy (PN) and the relationship of the number of these agents used during surgery with tumor size, RENAL nephrometry score (NS), peroperative ischemia time, and postoperative pathology results. Materials and Methods: Records of patients, who had undergone PN in our clinic due to renal mass between January 2013 and February 2019, were retrospectively reviewed. Our study included 71 patients who were administered one or more HAs during PN. Demographic characteristics, operative data, and pathological results of patients, who were administered one or more HAs during PN, were recorded. Results: Cellulose-based agents and polytetrafluoroethylene pledgets were the most frequently used HAs (78.8% and 38%, respectively). The patients were divided into two groups according to tumor size (0-4 cm and larger than 4 cm tumors), RENAL NS (low and intermediate-high score), ischemia time (0-20 min and longer than 20 min), and tumor pathology result (benign and malignant tumor), and the number of HAs used in each group was compared. When the groups were compared separately in terms of number of HAs used, no statistically significant difference was found between the groups (p=0.323, p=0.183, p=0.618, and p=0.131, respectively). Conclusion: HAs are frequently used in our clinic to achieve hemostasis. There was no statistically significant difference in the number of HAs used between the groups.
