Hemopatch as a Hemostatic Agent is Safe in Partial Nephrectomy: A Large, Single-Surgeon Retrospective Evaluation.

INTRODUCTION

Partial nephrectomy (PN) has evolved into the surgical standard of care for localized renal lesions. Hemostatic agents (HA) support the surgeon in achieving local hemostasis during PN. We previously reported initial results with the HA Hemopatch in PN. We now report our experiences with Hemopatch in a larger and more challenging single-surgeon PN cohort.

METHODS

Our study included 45 patients who underwent PN due to suspicious renal lesions between December 2013 and March 2018. All surgeries were performed by a single surgeon using the HA Hemopatch. Preoperative, intraoperative, and postoperative parameters were assessed.

RESULTS

Preoperative median tumor diameter was 27 mm. Median PADUA and RENAL nephrometry scores were 7 and 6, respectively. In 13.3% of the cases an additional HA was applied. Intraoperative and postoperative bleeding occurred in 2.2% and 8.9%, respectively. Median total blood loss was 200 ml. Urgent pedicle clamping due to bleeding was necessary in 2 (4.4%) patients. The transfusion rate was 8.9%. There were no conversions.

CONCLUSION

We confirmed our initial results demonstrating feasibility and reliability of Hemopatch during PN. Notably, the cohort consists of selected patients. Prospective randomized studies are needed for comparison of different types of HA with regard to perioperative outcome.
