SUMMARY After they were first identified in the mid-1980s, vancomycin-resistant enterococci (VRE) spread rapidly and became a major problem in many institutions both in Europe and the United States. Since VRE have intrinsic resistance to most of the commonly used antibiotics and the ability to acquire resistance to most of the current available antibiotics, either by mutation or by receipt of foreign genetic material, they have a selective advantage over other microorganisms in the intestinal flora and pose a major therapeutic challenge. The possibility of transfer of vancomycin resistance genes to other gram-positive organisms raises significant concerns about the emergence of vancomycin-resistant Staphylococcus aureus. We review VRE, including their history, mechanisms of resistance, epidemiology, control measures, and treatment.

In patients whose preoperative urine cultures are sterile, short-term prophylaxis has no advantage over single-dose prophylaxis as a means of preventing infection. The duration of surgery and the amount of irrigation fluid are significant risk factors for postoperative fever.

Fever and bacteriemia after PCNL are common, through progression to sepsis is rare. Recovery is possible with a high degree of suspicion, early intervention and intensive treatment. The results of cultures taken preoperatively, peroperatively and during the febrile period have great importance for decision of required changes during the treatment.
