By measuring intrarenal pressure in renal time, we were able to determine if the pressure may become elevated and contribute to potential postoperative complications. METHODS: The LithoVue Elite Ureteroscope was used clinically and the first in human cases have occurred in Canada. A pressure bag set at 150 mmHg was used for pressurized irrigation. A ureteral access sheath was used at the discretion of the surgeon. Pressure readings were delivered 4 times a second. Readings of the intrarenal pressure are displayed on the video interface where the endoscopic image is viewed in real time (Figure 1). RESULTS: Two cases are discussed here. One case shows that the intrarenal pressure with a ureteral access sheath ranges between 25-30 mmHg. In the exact same patient on the other kidney, no ureteral access sheath was used and the pressure is seen to be approximately 100 mmHg. Another case shows a patient under spinal anesthesia. When the pressure goes >115 mmHg, the patient describes pain and insertion of a UAS lowers the pressure to 15 mmHg and her pain subsides. CONCLUSIONS: The LithoVue Elite ureteroscope was able to monitor intrarenal pressure in real time. Ureteral access sheath use in these 2 cases showed a decrease in intrarenal pressure and where the patient was awake under spinal anesthetic, a UAS decreased her pain from high intrarenal pressure. The use of a new ureteroscope that can monitor intrarenal pressure in real time will help further investigation of the effects of intrarenal pressure during and after ureteroscopy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
