Preliminary Evaluation of High Frequency Jet Ventilation in RIRS from a Tertiary Center

PurposeRetrograde intrarenal surgery (RIRS) is an effective and safe therapeutic option in the treatment of renal stonesu carbon dioxide concentration measured at the end of expiration,the normal values of which are 4-6%) before HFJV - 4,81 % (4,1-5,8) and after HFJV 5,22 % (3,9-7,2) respectively. No signs of respiratory impairment were detected. The operative time ranged between 20- 102 min. The renal movement reduction with HFJV was of significantly noticeable by the surgeon. Three patients were readmitted to the hospital; one of them due to a urinary tract infection. No perioperative pulmonary complications were reported. ConclusionHFJV is a safe, feasible method that can be used in RIRS and can significantly enhance the efficacy of the procedure. However, further evaluation of the method is needed.
