Laser photoablation of renal pelvic tumours
Bibliographic record
Abstract
We evaluated the clinical effects of the Zeiss OPMILAS (Oberkochen, Germany) multi-yttrium-aluminum-garnet (YAG) laser in the treatment of renal pelvic tumours as an alternative to nephroureterectomy. Four patients with evidence of transitional cell carcinoma (TCC) in the renal pelvis and a previous history of TCC of the bladder or opposite renal pelvis were treated with the Zeiss OPMILAS multi-YAG laser. Three patients underwent a retrograde ureteroscopic approach and 1 patient required percutaneous resection. Two wavelengths were used: 1060 nm continuous coagulative mode and 1440 nm pulsed ablative mode. The patients were followed for 12, 24, 76 and 84 months, respectively. Two patients showed no evidence of recurrence as determined by cystoscopy, retrograde pyelography and selective pelvic urine cytology. One patient experienced a recurrence of TCC requiring subsequent treatment. The ureteroscopic approach was associated with fewer complications and a more rapid recovery, compared with the percutaneous approach. All patients with solitary kidneys avoided dialysis.

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.
