    AbstractBackground: Complicated urinary tract infections are a significant cause of morbidity, hospitalization, and elevated hospital costs associated with kidney transplantations. The treatment of complicated urinary tract infections is very challenging, due to varying severities of infection and lower cure rates. The available drug options for treating these infections are limited, each with different mechanisms of action, efficacy, and safety profiles, making drug selection more difficult for healthcare professionals. Objectives: A systematic review was conducted to evaluate the safety and efficacy of drugs approved by the United States Food and Drug Administration for the treatment of complicated urinary tract infections between 2016 and 2023. The primary endpoint for all drugs used in treating complicated urinary tract infections was the cure rate. Results: Among the drugs used for treating complicated urinary tract infections, meropenem had the highest cure rate at 91.4%, followed by plazomicin at 88% and cefiderocol at 73% when used as monotherapy. In combination therapy, meropenem-vaborbactam had the highest cure rate at 98.4%, followed by piperacillin-tazobactam at 94%, and ceftazidime-avibactam at 87.5%. The safety profiles of the drugs indicated that almost all drugs caused gastrointestinal symptoms, with imipenem-relebactam and colistin-imipenem combinations having the most serious adverse events. Cefiderocol had a low magnitude of adverse events, with most side effects being mild gastrointestinal symptoms. Conclusion: The study concludes that appropriate drug selection and treatment adherence are crucial for preventing complicated urinary tract infections and improving health outcomes.
