Retrograde intrarenal surgery (RIRS) is a minimally invasive procedure increasingly used to treat renal stones and other intrarenal pathologies due to its reduced risk of complications, shorter recovery time, and lower postoperative pain compared to more invasive surgical techniques. However, despite its advantages, RIRS is associated with a significant risk of infectious complications, ranging from simple urinary tract infections (UTIs) to severe systemic infections such as urosepsis, which can lead to increased morbidity, prolonged hospitalization, and, in severe cases, mortality. This review aims to summarize the current knowledge on preventing and managing infectious complications associated with RIRS. By exploring the pathophysiology of these infections, identifying patient and procedural risk factors, and evaluating evidence-based strategies for prevention and management, this review provides comprehensive insights into minimizing infection risks in RIRS. A thorough literature review was conducted, examining studies and clinical trials that address the incidence, risk factors, prevention strategies, and management protocols for infections in RIRS. This review also assesses current guidelines from professional organizations and recent infection control technologies and practices advancements. The review identifies multiple risk factors contributing to infections in RIRS, including patient-specific factors such as comorbidities and procedural factors like the duration of surgery and use of instrumentation. Effective prevention strategies include preoperative antibiotic prophylaxis, stringent aseptic techniques during surgery, and careful postoperative monitoring. The review also highlights the importance of a multidisciplinary approach involving urologists, infectious disease specialists, and microbiologists in managing complex cases of infection. Infectious complications remain a significant concern in RIRS, necessitating a comprehensive approach to prevention and management. By adhering to evidence-based guidelines and utilizing a multidisciplinary strategy, healthcare professionals can significantly reduce the incidence of infections, thereby improving patient outcomes and the overall safety of RIRS. Future research should focus on advancing infection control technologies and developing novel prophylactic and therapeutic approaches to further enhance the safety and effectiveness of RIRS.
