Among the three groups, no differences were detected in the rates of medical and surgical complications, transfusion and re-intervention due to bleeding, as in variations between pre and postoperative levels of hemoglobin and glomerular filtration rate, overall and pairwise. Therefore, from these results, it seems that HA cannot exert any significantly protective effect against bleeding with respect to standard suturing. A possible explication is that HA is often used improperly or indiscriminately. This statement is indirectly confirmed by the fact that, in spite of their frequent use, a reduction in the rate of bleeding was not observed in recent with respect to past series of PN. Conclusions No differences in terms of overall and bleeding complications were detected among patients submitted to NSS without using HA, using Floseal® or Tachosil®. There is no clear evidence that the use of HA, in addition to sutures, can improve haemostasis after PN.

Abstract

Aim of the study The aim of this study is to investigate the efficacy of hemostatic agents (HA) in Nephron Sparing Surgery (NSS). A three-matched comparison between patients treated with no HA, with Tachosil® and with Floseal® was performed. Materials and methods Observational multicentre study (RECORd Project) collects the data of 1055 patients who underwent PN between January 2009 and December 2012 at 19 Italian centres. Cases treated with more than one HA or with HA other than Floseal® or Tachosil® were excluded. A tri-match propensity score analysis was applied to create 3 groups - no HA group, Floseal® group, Tachosil® group - balanced for gender, age, surgical indication (elective/relative vs imperative), clinical stage (cT1a vs cT1b), tumour growth pattern, surgical approach (open vs minimally invasive), surgical technique (standard PN vs simple enucleation), preoperative haemoglobin and preoperative creatinine.
