Preliminary Evaluation of High-Frequency Jet Ventilation in RIRS from a Tertiary Center
Bibliographic record
Abstract
Purpose Retrograde intrarenal surgery (RIRS) is an effective and safe therapeutic option in the treatment of renal stones&upper tract urothelial carcinoma. High frequency jet ventilation (HFJV) is a lung ventilation mode offering a substantial reduction of renal movement. In our pilot study, we evaluated a HFJV ventilatory protocol in endoscopic treatment of renal stones. Materials and methods 15 consecutive cases of the treatment of renal stones larger than 7mm have been included in our study, with exclusion of patients suffering from severe pulmonary disease. Total intravenous anesthesia has been chosen with intraprocedural HFJV. The intraoperative gas exchange parameters, as well as eventual postoperative respiratory adverse events were taken note of. A laser stone disintegration has been performed in all procedures, including a three-month postoperative follow-up. Results Mean duration of HFJV procedure was 56,3 min (35-110), Et CO2(end tidal ; 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. Conclusion HFJV 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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
