Abstract
Percutaneous cystolithotomy (PCCL) is a minimally-invasive technique for removal of cystoliths. There is currently no information regarding optimum patient positioning during PCCL. The objective of this study was to assess whether patient positioning affected ease of cystolith retrieval via PCCL. PCCL was performed to retrieve artificial “cystoliths” in three canine cadavers weighing between 15 and 35 kg, using a threaded cannula and a rigid 30◦ 2.7 mm cystoscope. “Cystolith” retrieval was performed by retrograde flushing and use of a flexible stone basket, with the dog in 10◦ Trendelenburg, 10◦ reverse Trendelenburg, or neutral position. The location of the “cystoliths”, number retrieved during flushing, and total time for retrieval were recorded and compared between different positions. The mean total time for “cystolith” retrieval was 392 ± 131 s, with 162 ± 20 s for flushing and 221 ± 123 s for basket-retrieval. The mean number of “cystoliths” retrieved during flushing was 3 ± 2. No significant differences were detected when comparing retrieval times between different positions. The predominant location of the “cystoliths” within the bladder varied depending on the position of the dog. In neutral, 93 % were located adjacent to the ureteric openings, whereas in 10◦ reverse Trendelenburg, 100 % were located by the urethral orifice. In 10◦ Trendelenburg, 60 % “cystoliths” were located at the tip of the cannula. Cystolith retrieval during PCCL can be performed in either neutral, Trendelenburg or reverse Trendelenburg position. Changing the dog’s position may be useful in cases where cystolith retrieval is challenging, to move the cystoliths and enable different techniques to be employed using the stone basket.

How this classification was reachedexpand
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.
