ABSTRACT
Objective – to study the character of possible postoperative complications and to define the reason and frequency of postoperative hemorrhage as a complication of partial nephrectomy. From January 2008 to December 2019 were performed 175 partial nephrectomy (PN) by a single surgeon in a high volume center. 41 operations were laparoscopic partial nephrectomy (LPN), 134 – open partial nephrectomy (OPN). In 152 cases kidney cancer was detected. Physical status, tumor volume, R.E.N.A.L. score, operative access, warm ischemia time (WIT), postoperative bleeding and its severity and treatment options were assessed in both groups of patients. Based on our study, R.E.N.A.L score may be a good tool in prognosis of a delay postoperative bleeding after nephron sparing surgery and this is statistically significant. On the other hand, single R.E.N.A.L score characteristics can’t be reliable predictors of a delay bleeding. It is possible that a lack of cases with a significant postoperative bleeding in current study (6 of 175 cases) have some statistical restrictions. From our point of view, for better prognosis of delay bleeding, aside from hephrometric system it is important to take into account a proximity of a segmental arteries to a resection border, presens of any type of a coagulopathy and a preoperative antithrombotic therapy, obesity. High R.E.N.A.L score index is connected with a risk of significant postoperative bleeding, but this type of bleeding is rare after any nephron sparing surgery. Postoperative selective angioembolization is a method of choice and, in most cases, effective to stop kidney bleeding and nephron preservation.
