Infected Kidney Stones Linked with Increased Risk of Sepsis after Removal

After adjustments, positive stone culture was independently associated with a 6.9 times increased likelihood of postoperative sepsis after stone percutaneous nephrolithotomy in a recent study. Postoperative sepsis occurred in 31% of the 45 patients who had a positive stone culture vs. 5.9% of the 161 patients who had a sterile stone culture. Among the patients with positive cultures, Enterococcus species (29.4%) and Escherichia coli (21.6%) were the most prevalent gram positive and gram negative bacteria, respectively. Quinolone resistance was high in both gram negative and gram positive bacteria, according to the Urolithiasis study.
