Comparison of results of open simple nephrectomy secondary to lithiasis in patients with and without nephrostomy

Abstract

Abstract Background Simple nephrectomy is the procedure of choice in the treatment of excluded kidneys. The purpose of this study was to describe and compare surgical results in open simple retroperitoneal nephrectomies in patients with and without nephrostomy. Methodology 58 patients were analyzed. The demographic parameters of patients with nephrostomy were compared to patients without nephrostomy (age, gender, weight, lithium localization, transoperative variables (surgical time, transoperative bleeding) and postoperative variables (need for intensive care, need for transfusion, surgical wound infection and hospital stay days) Results Statistically significant differences were found for the variables of operative bleeding ( p = 0.0442), surgical time ( p = 0.0093), hospital stay days ( p = 0.0040), and transfusion requirements ( p = 0.0170). There were no differences in the need for intensive care ( p = 0.6314), transoperative complications ( p = 0.7414) and surgical wound infection ( p = 0.2762). Conclusions The presence of a nephrostomy catheter in patients undergoing open simple nephrectomy leads to an increased risk of morbidity, with increased bleeding, surgical time, need for transfusion, and hospital stay days.
